Rupert Brown, an Isle of Wight musician, mixes nature sounds with music to create a soundscape that helps distract his brain from the tinnitus.
“The island is my orchestra,” says Brown in a BBC video, about his efforts to record waves crashing, birds twittering, and wind in the trees, which he then mixes in the studio with non-classical music and the sounds of what he believes are others’ type of tinnitus to form the soundscape.

By Laura Winther Balling, PhD, Oliver Townend, BSc, and Dana Helmink, AuD
Sound quality plays a key feature for overall hearing aid satisfaction as well as in everyday moments of real-life hearing. A large international survey of hearing aid users confirms the importance of sound quality, showing higher satisfaction with the WIDEX MOMENT™ hearing aids for overall sound quality, for specific situations of real-life use and for hearing aid users’ ability to participate in daily life.
As one of the major global hearing aid manufacturers, Widex has a long history of focusing on sound quality, designing all signal processing with the aim of achieving the best and most natural sound quality possible. For example, True Input Technology, with a linear transfer function up to 113 dB SPL and a linear input dynamic range of 108 dB SPL, was groundbreaking when launched,1 as was Variable Speed Compression, which offers the benefits of both slow and fast-acting compression.2
Most recently, WIDEX MOMENT™ launched with the focus on sound quality expressed in two main features:
TruAcoustics™ is an intelligent algorithm by which the acoustics in the individual ear canal is integrated in the parameter settings of the hearing aid, so the output at the eardrum is exactly right for the individual ear canal with the specific earware choice.3
Widex PureSound™ drastically reduces hearing aid delay and eliminates the delay-based distortions which are characteristic of other digital hearing aids.4
Innovations like these improve the sound quality in clearly audible ways and result in sound quality preferences in studies, such as the one reported by Balling et al.4 However, it is also an important assumption of the Widex design philosophy that good sound is not an isolated quality but a means to achieving higher hearing aid satisfaction across many situations in real life. With this broader view of sound quality, it is arguably the most important parameter for hearing aid satisfaction, along with speech understanding (especially in noise).
For these reasons, the survey reported below focused on satisfaction with sound quality in itself, as well as the experience in diverse situations of real-life hearing with Widex MOMENT hearing aid.
Survey Method
Our survey included 101 experienced hearing aid users recruited at local hearing clinics in 7 countries (US, Canada, China, Germany, France, Portugal, UK). They all wore the MOMENT mRIC R D rechargeable hearing aids and rated their satisfaction with them in comparison to their own existing hearing aids, which were from all major brands. Respondents were 60% male with a median age of 66 years (range 18-88). Close to half (45%) were work active, and they had a median of 6 years’ hearing aid experience (range 1-59 years).
Respondents fell into two groups: 39 of them had mild-to-moderate hearing losses going from 40 dBHL at low frequencies to 70 dBHL at high and had as their primary program PureSound™, which is particularly suitable for open fits and milder losses. The other 62 respondents had hearing losses up to 80 dB HL across frequencies (the mRIC M-receiver fitting range) and were fitted with the Universal program as their primary program. The MOMENT hearing aids were fitted with the ear tip recommended in the Compass GPS fitting software.
The survey used a cross-over design where respondents started a 7-week survey period by rating their satisfaction with their own existing hearing aids before being fitted with the MOMENT hearing aids and wearing them for 3 weeks. After 3 weeks, they rated their satisfaction with the MOMENT devices, before switching back to their own hearing aids, wearing those for 2 weeks and rating them at Week 6. For the final 2 weeks of the survey, respondents wore MOMENT and filled in a final set of questions about those at Week 7. This resulted in two ratings for own hearing aids (at Weeks 0 and 5) and two for MOMENT (at Weeks 3 and 7).
The questionnaires were filled in online using SMART-TRIAL software, using a format inspired by the MarkeTrak surveys,5 where respondents rate their satisfaction with their hearing aids on a 7-point scale ranging from “Very dissatisfied” (a rating of 1) to ‘Very satisfied’ (a rating of 7). Following the MarkeTrak approach, respondents who gave ratings in the top-3 satisfaction categories may be classified together as being “satisfied.” We asked questions about satisfaction both in general and in specific real-life situations.
The responses show that people are reasonably satisfied with their own hearing aids at the beginning of the survey period, but once they try the MOMENT hearing aids, their ratings of their own hearing aids in many cases become significantly lower. This in itself is evidence in favor of the MOMENT devices. However, the more interesting direct comparison is between the ratings of own hearing aids in Week 5 and MOMENT in Week 7, where respondents have had the most time to form an opinion about the new hearing aids.
We also estimated the age of the respondents’ own hearing aids based on the launch date of the device. Interestingly, we found no significant effects of this variable, indicating that the MOMENT advantages that we observe throughout are not simply explained by the contrast between older own hearing aids and new MOMENT devices, but by a genuine preference for the MOMENT sound.
Unless otherwise indicated, statistical testing of results was done using mixed-effects models that take into account the crucial fact that we have multiple responses per person. The significance levels for the relevant contrasts between own and MOMENT hearing aids are all below 0.0001, which means that potential concerns about repeated testing are unfounded.
Sound Quality Across Situations
As we would expect given the Widex design focus, the responses show a solid sound quality advantage for the MOMENT hearing aids, with significantly higher satisfaction for MOMENT than for own hearing aids (p < 0.0001). Looking at the average ratings plotted in the left panel of Figure 1, there is a 1-point advantage for MOMENT, with the average rating “Satisfied” for MOMENT and “Somewhat satisfied” for own hearing aids. Examining the distribution of answers in the right panel of Figure 1, we see many more “Very satisfied” and “Satisfied” MOMENT users. In total, considering the top-3 satisfaction categories, 91% of respondents are satisfied with the MOMENT sound quality.
Figure 1. Ratings of satisfaction with sound quality. The left panel shows mean ratings of satisfaction with sound quality as filled circles, with the whiskers representing ±1 standard deviation (SD) around the mean. The right plot shows ratings of own hearing aids in Week 5 and of MOMENT hearing aids in Week 7 of the survey.
An intriguing question is which aspects of sound and hearing aid use influence these high-satisfaction sound quality ratings. This is a complex issue that this survey cannot fully address, but it is informative to look at which other questions are correlated with sound quality satisfaction. In Table 1, such correlations are listed for the ratings of MOMENT at the end of the survey period. They are all strong correlations ranging between 0.522 to 0.698, and although there is some variation between individual situations, the correlations are all highly significant and of similar size. These correlations do not, of course, indicate causation but do suggest that sound quality plays a similar role across different situations.
Table 1. Spearman Rho correlations between sound quality satisfaction and satisfaction in specific situations for WIDEX MOMENT. (Notations: *** indicates significance at the p<0.001 level; a) Speech-in-noise situations; b) Outdoor situations; c) Listening through devices.
Another way of assessing the impact of sound quality on everyday satisfaction with hearing aids is analyzing the average satisfaction across the specific situations listed in Table 1 (excepting satisfaction with soft and loud sounds, which are not specific situations). A regression model shows that satisfaction with sound quality is a highly significant predictor of mean satisfaction across situations, accounting for more than 50% of the variance in satisfaction across situations (R2 = 0.51).
Sound Quality and Naturalness
In addition to the different listening situations, Table 1 also lists respondents’ agreement with the statement “I find that the sound is natural with the MOMENT hearing aids” on a 7-point scale. This shows one of the highest correlations with sound quality satisfaction, which means that those hearing aid wearers who are highly satisfied with the sound quality also perceive the sound as more natural.
In addition, naturalness ratings show a very similar pattern across weeks to sound quality satisfaction, as illustrated in Figure 2. Again, we see approximately a 1-point difference between the ratings of own and MOMENT hearing aids, and many more who “Agree” or “Strongly agree” that the sound of MOMENT is natural.
Figure 2. Ratings of naturalness of sound, with the left panel showing mean ratings per week and the right panel showing ratings for own hearing aids in Week 5 and for MOMENT in Week 7.
Satisfaction in Everyday Situations
As seen in Table 1, the survey included questions on a wide range of everyday situations. In Figure 3, these are grouped into four different more general categories, showing the distribution of ratings in Week 5 (own hearing aids) and Week 7 (MOMENT hearing aids).
Figure 3. Histograms showing distribution of ratings in Weeks 5 (own hearing aids) and 7 (MOMENT hearing aids).
The top-left panel shows the satisfaction with conversations in quiet, assessed by a single question. Level of satisfaction is generally high, as we would expect for this relatively easy listening environment. However, although the baseline is already high, the MOMENT ratings are still higher, with the most frequent response being “Very satisfied” and the difference to own hearing aids being highly significant (p < 0.0001).
Speech-in-noise ratings are shown in the top-right panel, based on a mean across questions on satisfaction in restaurants and with conversations in noise and during transport. These tend to be difficult situations for hearing aid users, which is also clear if we compare the general level of satisfaction with speech in quiet. This makes the significant advantage for MOMENT (p < 0.0001) all the more noteworthy: the most frequent mean rating for these questions is clearly in the “Satisfied” category for MOMENT, whereas ratings for own hearing aids are more spread out, with “Somewhat dissatisfied” as the most frequent. If we compare the own-vs-MOMENT hearing aid ratings per respondent, five times as many respondents are more satisfied with the MOMENT hearing aids compared with their own: 74% of respondents are more satisfied with MOMENT, 12% more satisfied with their own, and the remaining 14% give the same ratings to both.
The bottom left panel illustrates mean ratings in outdoor situations, again with a markedly differently distribution of ratings for own and MOMENT hearing aids (p < 0.0001). Part of the explanation for the MOMENT advantage could be that respondents experience the sound of MOMENT as more natural, something that is likely to play a larger role outdoors.
The final panel of Figure 3 represents the frequent listening situations where sound comes from a device, with TV likely being the most frequent for most people, but also telephone and music. As for conversations in quiet, the general level of satisfaction is higher here than for more difficult listening situations, but the MOMENT advantage remains, with a significant difference to own hearing aids (p < 0.0001). Collectively, the four types of situations illustrated in Figure 3 give a comprehensive view of the everyday lives of hearing aid users, and across all these situations MOMENT shows a solid advantage.
Participation in Daily Life
A common problem for people with hearing loss, reported both scientifically6,7 and by hearing aid users and their relatives to HCPs all over the world, is the difficulty of participating in everyday life. Therefore, the survey included a question inspired by the International Outcome Inventory for Hearing Aids (IOI-HA)8: “How satisfied are you with your ability to participate effortlessly in everyday life with [your own hearing aids/the WIDEX MOMENT hearing aids]?” The ratings for this question are shown in Figure 4, where both plots illustrate a similar 1-point MOMENT advantage that was also seen previously (p < 0.0001). An interesting statistic is how many people are satisfied (in the top-3 categories) with their ability to participate in everyday life; this number is 69% for own hearing aids but 90% for MOMENT. Conversely, only 6% of respondents indicate dissatisfaction with participation when wearing MOMENT, while the corresponding number is 20% for own hearing aids, in spite of the fact that the MOMENT devices are new to the respondents and they cannot be expected to be completely habituated to them yet.
Figure 4. Ratings of ability to participate in everyday life, with the left panel showing mean ratings per week and the right panel showing ratings for own hearing aids in Week 5 and for MOMENT in Week 7.
Overall Satisfaction
Finally, a question about overall satisfaction examines how all these different elements of real-life hearing come together in the respondents’ entire experience of wearing the MOMENT hearing aids, compared with their own. The responses to this question were tested in the same way as previous results, showing significantly higher ratings (p < 0.0001) for MOMENT than own hearing aids. The left panel in Figure 5 is a particularly clear example that respondents’ ratings of their own hearing aids change when they have tried MOMENT, as evidenced by the lower ratings in Week 5 compared to Week 0. More generally, Figure 5 confirms the MOMENT advantage that has also been clear in the more detailed questions, with the most frequent overall response to the MOMENT hearing aids being “Very satisfied.”
Figure 5. Ratings of overall satisfaction, with the left panel showing mean ratings per week and the right panel showing ratings for own hearing aids in Week 5 and for MOMENT in Week 7.
The Importance of Sound Quality in Real Life Hearing Aid Use
The results reported in this article show the importance of sound quality in many different moments of real life, confirming the Widex design philosophy that sound quality should be central. We see solid advantages for the MOMENT devices for sound quality satisfaction in general, as well as for ratings of a representative selection of real-life situations, and for the key factor of participation in daily life.
The results also show that sound quality should not be seen as a quality for experts only. The respondents in this survey were not selected to have a specific focus on sound quality; they represent a broad group of hearing aid users, with different lives and different (hearing) needs and wishes. Nonetheless, the results support the importance of sound quality, both as an overall phenomenon and as a continually relevant factor in many different situations of real-life hearing for many different people. So, although Widex does aim to fulfill the needs of musicians and other sound experts with great-sounding hearing aids, the target group is not limited to connoisseurs: the great sound quality of WIDEX MOMENT™ benefits everyone.

Neurophysiologists at the University of Connecticut (UConn) have discovered a new drug that may prevent tinnitus and treat epilepsy by selectively affecting potassium channels in the brain. According to an article in the June 10, 2015 edition of The Journal of Neuroscience, Anastasios V. Tzingounis, PhD, and colleagues say that both tinnitus and epilepsy are caused by overly excitable cells that flood the brain with an overload of signals that can lead to seizures (epilepsy) or phantom ringing in the ears (tinnitus).
The authors report that roughly 65 million people worldwide are affected by epilepsy. While exact statistics on tinnitus are not easy to determine, the American Tinnutus Association estimates that two million people in the US suffer from disabling tinnitus.
Anastasios V. Tzingounis, PhD, University of Connecticut
According to Tzingounis and co-authors, the existing drugs available to treat epilepsy don’t always work and can have serious side effects. One of the more effective drugs, retigabine, helps open KCNQ potassium channels, which serve as the “brakes” that shut down the signaling of overly excited nerves. Retigabine, however, has terrible side effects and is usually only given to adults who don’t get relief from other epilepsy drugs. The side effects of retigabine include sleepiness, dizziness, problems with hearing and urination, and a disturbing tendency to turn patients’ skin and eyes blue.
In 2013, Tzingounis began collaborating with Thanos Tzounopoulos, PhD, a tinnitus expert at the University of Pittsburgh, to create a new drug candidate. The new drug, SF0034, was chemically identical to retigabine, but included an extra fluorine atom. Originally developed by SciFluor, the company wanted to know whether the compound had promise for treating epilepsy and tinnitus.
Thanos Tzounopoulos, PhD, University of Pittsburgh
Tzingounis and Tzounopoulos thought the drug had the potential to be much better than retigabine in treating both conditions. They first had to determine if SF0034 worked on KCNQ potassium channels the same way retigabine does, and if so, if it would be better or worse.
The co-authors explain in their article that KCNQ potassium channels are found in the initial segment of axons, long nerve fibers that reach out and almost touch other cells. The gap between the axon and the other cell is called a synapse. When the cell wants to signal to the axon, it floods the synapse with sodium ions to create an electrical potential. When that electrical potential goes on too long, or gets overactive, the KCNQ potassium channel kicks in. The result is that it opens, potassium ions flood out, and the sodium-induced electrical potential shuts down.
In some types of epilepsy, the KCNQ potassium channels have trouble opening and shutting down runaway electrical potentials in the nerve synapse. Retigabine helps them open. According to the authors, there are five different kinds of KCNQ potassium channels in the body, but only two are important in epilepsy and tinnitus: KCNQ2 and KCNQ3. The problem with retigabine is that it acts on other KCNQ potassium channels as well. That’s why it has so many unwanted side effects.
When testing SF0034 in neurons, the researchers found that it was more selective than retigabine. It appeared to open only KCNQ2 and KCNQ3 potassium channels, and to not affect the KCNQ 4 or 5 potassium channels. The research showed that SF0034 was more effective than retigabine at preventing seizures in animals, and it was also less toxic.
The results are promising, and SciFluor plans to start FDA trials with SF0034 to test its safety and efficacy in people. Treating epilepsy is the primary goal, but treating or preventing tinnitus is a secondary goal.

Whisper may have a quiet name, but it could reverberate loudly in the hearing healthcare industry. The company launched its first new hearing aid on October 15—a product that really is significantly different from all others dispensed by audiologists and hearing aid specialists. And, yes, that’s right: the Whisper Hearing System is designed for dispensing by hearing care professionals. As such, Whisper represents the first new major hearing aid manufacturer with a product specifically designed for dispensing since the InSound Medical XT was approved by the FDA in 2003 (later purchased in 2010 by Sonova and renamed Lyric).
The Whisper RIC hearing aids and brain.
And a bit like Lyric, Whisper will use a subscription payment model for consumers. The leasing concept is gaining ground in hearing healthcare, in part due to the fact that technology moves so fast, hearing aids can be expensive, and frequent product upgrades are now a given in the industry. Whisper will be available via a comprehensive monthly plan that includes ongoing care from a local hearing care professional, a lease of the Whisper Hearing System, regular software upgrades, and a 3-year warranty that not only covers the system itself but also loss and damage. The company is offering a special introductory rate of $139/month (regularly $179/month) for a 3-year term.
The New Whisper Hearing System
The Whisper Hearing System essentially has three components:
A hearing aid processor that resembles an advanced receiver-in-the-canal (RIC) hearing aid;
The Whisper Brain is a small device that runs an AI-driven Sound Separation Engine to optimize sound in real time. It also enables connectivity to iPhones, and
A phone app that provides an interface for the consumer.
The Whisper team, which is largely composed of executives from the AI field, created the Whisper brain as a dedicated, powerful sound processing system that also allows for updates and other capabilities—instead of relying on the wearer’s smartphone for many of these functions. “We developed the Whisper Brain to run the core technology we’ve developed for hearing,” said company Co-founder and President Andrew Song in an interview with Hearing Review. “Think about your smartphone and all the processing inside it. We’re using the Whisper Brain to apply this type of processing to hearing without having to compete with smartphone games or applications. The Whisper Brain is a dedicated processor designed to provide the best hearing.”
However, the Whisper Brain isn’t required to use the hearing aid, as there may be situations where the wearer wants to step away from it or not take it with them. In those situations, the hearing aid uses the “onboard” hearing aid algorithms in the RIC (similar to other advanced hearing aids when unpaired to the user’s cell phone).
Wireless connectivity with iPhones is also provided through the Whisper Brain via Bluetooth, and the company says it may support other phones and has plans to expand on this in the future. The RICs use a size 675 battery with an expected use of 4-5 days with typical use including streaming, and the WhisperBrain has a USB port for recharging.
Not Your Grandfather’s Hearing Aid
Andrew Song
According to Song, Whisper started about 3 years ago in San Francisco when he began discussions with another Whisper co-founder, Dwight Crow, the company’s CEO. Song is the former head of products for an online instant-messaging (IM) system most of us are familiar with: Facebook Messenger Core. A mathematics and computer science graduate of the University of Waterloo, he is an expert in artificial intelligence and a member of Sequoia Capital’s Scout Program which was formed to discover and develop promising companies. Crow is the founder of Carsabi, a machine-learning based car sales aggregator acquired by Facebook in 2012, and he helped build the e-commerce segment at Facebook which yields over $1 billion per quarter in revenue. A third co-founder, Shlomo Zippel, was the applications team leader at PrimeSense which built the 3D sensor technology behind Microsoft Kinect.
Jim Kothe
The company then added as head of sales Jim Kothe, an audiologist and hearing industry veteran who has a wealth of experience within both the dispensing community and manufacturing, in addition to an extremely impressive team of executives with experience and leadership roles at companies like Facebook, Nest, Google, Invisalign, Johnson & Johnson, Solta Medical, and Cutera. Together they are collaborating on a product that blends artificial intelligence, hearing care, hardware, and software for helping solve the challenge of providing better hearing.
“I think for me, and probably for everyone at the company, it’s a very personal mission,” says Song. “Personally, the starting point is really my grandfather. He has hearing loss and is not an uncommon story when you work in this business: I’d say that he’s a hearing aid owner, but not a hearing aid wearer.”
This set into motion Song’s investigation into what hearing aid technology was doing, what experiences people were having with it, and why his grandfather had the complaints he did. “That really opened my world to all the exciting things that could be done, but also the opportunity we have for how we can really build a product to help [people like him],” says Song. “Since then we’ve been putting the product together and bringing the expertise that comes from hearing folks like Jim and the others on our team—and blending it with the kind of product and technology ideas we almost take for granted here in Silicon Valley. Products are becoming more consumer friendly, more consumer oriented, and we’re building some of those ideas into a new type of hearing aid product. So, while Whisper is a hearing aid regulated by the FDA, all of these things influenced our approach, our mentality, and our vision towards this space, and we think our approach is a little different [from those of other hearing aid manufacturers].”
The larger capacity for processing power is extremely exciting for Song and his colleagues, and he likens this advancement to the leap from analog to digital hearing technology.
The larger capacity for processing power is extremely exciting for Song and his colleagues, and he likens this advancement to the leap from analog to digital hearing technology. He says some great hearing aid algorithms have been, and will continue to be, created that will result in substantially improved hearing. However, there’s little point in having these algorithms if they can’t be fully employed in a wearable device.
He also says the problem in hearing aids is much more complex than, for example, those solutions found in noise-cancelling headphones. “Over time, [we’ve had] very ambitious people with a lot of ideas on what we should do with this powerful processing. What’s really exciting is not just having this technology, but also having a learning platform to be able to develop it. I think one of the most interesting parts of development is that the goal, at the end of the day, really isn’t about perfect noise removal. You need noise in your life. We have demos we can run that more or less perfectly remove noise…and it just creates sort of a weird environment. So, I think in many cases, the unique aspect of what we’re doing revolves around how do we use [the research] and how do we invent some truly novel ideas? Obviously, it’s not only about noise removal, but how we can use the powerful processing specifically in these hearing aids to make hearing aids really good for the purpose of listening. That subtlety is where we feel like we can really differentiate ourselves and truly make a difference in people’s lives.”
A System that Relies on Professional Care
Song says there has been a patient-centric approach at every turn in the design, development, marketing, and especially distribution of the Whisper Hearing System. And it starts with the hearing care professional’s expertise.
“I think there’s several very important things along that path; the first of which was to work with hearing care professionals who are the ‘artists’ in delivering great care,” Song told HR via a Zoom interview. “If I look at my grandfather’s experience, it was pretty obvious to me that having the right professionals made a huge difference. And so you can talk about using Zoom or you can talk about going direct to consumer, but it’s very, very obvious—even as a Silicon Valley engineer—that the audiologist is extremely important in the process. That’s why we made a decision very early on that we’d be working with professionals. And if you remember, when the company started in 2017, that’s when the OTC laws were getting passed. That’s where all the ‘cool stuff’ was supposed to be. Everyone was saying, ‘Get rid of these professionals!’ …But there’s a care-oriented mindset in hearing healthcare. You can see that there’s a personal aspect [needed] to evaluate what would be good for my grandfather. And when you talk to patients and you talk to audiologists, this becomes very clear. So, I think that was a very early decision that’s not necessarily about the product, per se, but about our business and how we best deliver the hearing system.”
One of the things Whisper also wants to address is the post-purchase feeling of regret that can accompany a high-end, high-technology purchase. As with any car, computer, or consumer electronics device, when a consumer purchases an expensive top-of-the-line hearing aid, there is doubtlessly a more advanced model with new processing capabilities and features that will be launched 6 months later. But, with hearing loss, Song believes that sense of regret can be magnified because hearing is such a personal, important 24/7 activity.
The Whisper Hearing Aid Brain
That led to the idea of a subscription-based system using a machine-learning platform that can be upgraded on regular intervals without continually replacing the actual hearing aid or brain itself. “The nature of our product is that it gets better over time. You don’t need to pay for [the upgrades]; the hearing aid learns on its own, and we’ll also deliver you a software upgrade every few months. [It’s] similar to how you might think of a cell phone plan…Fundamentally, that’s really what we’re trying to offer.”
It’s also important that professionals have the margins and revenues to be able to cover their expenses in order to provide exceptional hearing care, says Song. Whisper plans to provide upfront fees and work with professionals, while offering patients a better way to pay for the product, support, and systems that the company has developed. Currently, a select number of hearing care professionals are using the Whisper Hearing System, and the company is now expanding from this base of dispensing offices.
When asked how he thinks Whisper will change the hearing aid market, Song quickly replied, “I really hope that everybody around the world gets an upgradable hearing aid in the next 5 years. And, of course, I hope it’s ours. We have a lot to offer. But if the market moves toward Whisper in 5 years, then we’re competing with everybody to make the best upgrades. Frankly, I think that’s a big win for the industry. And it’s also a big win for my grandfather, right? I think, as part of that vision, we have to be really mindful about how much we bite off in any of our product development. So this first product represents a first step, especially on the device with this kind of learning capability and working with professionals on this payment model—all of the new things that we’ve already talked about. But there are other aspects around this kind of patient-centric, consumer-centric model with the professional and I think there’s a lot of interactivity that we can build on. There’s a lot of new ideas we have about how to better integrate everything together. And so, more and more, we’ll be able to build that out and address those issues because we’ll have an excellent learning hearing aid on the market.”
Funding for Whisper
The initial investment to establish the company came from Sequoia Capital and First Round Capital, and on Thursday (October 15) Whisper announced the close of a $35 million Series B funding round led by Quiet Capital for total funding of $53 million. Advisors for the company include Mike Vernal of Sequoia and former VP of engineering at Facebook; audiologist Robert Sweetow who is the former UCSF Director of Audiology; Lee Linden of Quiet Capital and founder of TapJoy and Karma; Rob Hayes of First Round which also invested in Uber and Square, and Stewart Bowers, former VP of engineering at Tesla who was responsible for AutoPilot.
“Software-defined hearing technology is the future,” said Vernal in a press statement. “By building the Whisper Hearing System around software, the Whisper team will be able to improve patient care with a device that adapts, upgrades, and improves continuously for the wearer’s benefit. This is the start of a new paradigm for delivering hearing technology, and we’re thrilled to partner with Whisper on this journey.”
“What I look for in a company is the team,” said Hayes. “The Whisper team combines incredible expertise in cutting edge artificial intelligence, software, and hardware with a genuine passion for helping people. I’m excited to work with them to transform the hearing space.”
University of Auckland to Study Chatbot Technology for Potential Tinnitus Therapy
Chatbot technology that offers therapy for tinnitus sufferers via a mobile device such as a smartphone will be trialed at the University of Auckland, according to an announcement on the school’s website.
Researchers are recruiting participants for the “Tinnibot” study which is aimed at helping those who suffer from a hearing disorder that affects around one in ten New Zealanders and more than 700 million people worldwide.
Tinnitus is usually experienced as a ringing in the ears but sufferers report a range of noises including buzzing, clicking, and even the sound of cicadas. Severity varies: sounds can be continuous or intermittent but the condition is linked to serious mental health effects including depression, anxiety, and insomnia. Currently there is no cure.
But as online technologies and devices such as smartphones change the way health care is delivered, Dr Fabrice Bardy from the University of Auckland’s School of Psychology says it has created new opportunities to treat tinnitus and to study which treatments work best.
Dr Fabrice Bardy
Tinnibot is a chatbot program which uses Cognitive Behavioural Therapy (CBT), proven to be effective in the treatment of tinnitus but usually only available through one-on-one sessions which can be expensive and involve long wait times.
The chatbot’s software interface delivers CBT designed for an individual’s needs directly to their mobile, conducting an automated and interactive text conversation designed to help people regulate their thoughts by focusing on positive thoughts and challenging negative ones.
The interface incorporates a sound therapy library which has proved to be effective tinnitus therapy, particularly for those who have trouble sleeping. It works by using noise at just the right volume to drown out the sounds tinnitus can produce.
Keynsham hearing centre
Dr Bardy describes Tinnibot to be like having a tinnitus expert in your pocket.
“This chatbot interface is the first one designed specifically for the treatment of tinnitus, a tool that offers direct therapy and support which is convenient and affordable,” he said. “It will help people better understand their condition and to manage symptoms, give them a sense of being in control, and a confidence boost because that’s an important part of successful treatment.”
Participants in the research will be split into two cohorts with one using Tinnibot only and the other using Tinnibot as well as video counseling with a psychologist. The aim is to see which treatment is more effective.
If you have been bothered with tinnitus for over three months and if you are interested in participating in the study, contact Dr Bardy for more information.
Signia announces the launch of the Styletto X. This new device, said to be “the world’s first SLIM-RIC form factor” pioneered by Signia, is now available on the Signia Xperience platform.
Styletto X reportedly offers “the most complete hearing experience, combining one-of-a-kind style that patients desire with the uncompromised technology that hearing care professionals demand,” according to the company’s announcement. Signia says that this “highly sophisticated hearwear helps to improves listening in any situation—even when moving—and delivers better-than- normal-hearing in difficult noise.” Features of the Styletto X include exchangeable receivers, portable rechargeability, Bluetooth connectivity, and self-service patient support via Signia Assistant.
In addition to Styletto X, Signia has introduced additional products on the Signia Xperience platform, helping to empower hearing care professionals to address more patient needs and preferences. These new offerings include:
The Silk X, a “discreet alternative to customs,” helping to allow hearing care professionals to operate more efficiently with a same-day-fit.
An expanded Essentials line to offer Signia’s advanced technology to more patients, regardless of budget.
Three new CROS solutions (CROS Pure Charge&Go X, CROS Pure 312 X, and CROS Silk X) for a choice of styles and fittings for patients with single-sided deafness.
“With its slim, rounded form and striking color combinations, Styletto X was developed to attract individuals who wouldn’t otherwise consider wearing hearing aids, while providing new options to existing wearers looking to upgrade to a sleek and modern device,” said Dr Tish Ramirez, AuD, Signia’s Vice President, Clinical Education & Professional Relations.
As evidence of its appeal, the eye-catching Styletto form factor—preferred by 8 out of 10 consumers—was found to significantly increase in-store-conversion of people with hearing loss into satisfied hearing aid wearers.2
Signia is the “first hearing aid brand” to incorporate Qi wireless charging technology, helping to enable wearers to place the Styletto X pocket-sized charging case on a charging pad for greater usability.
“Styletto X features several enhancements to this already well-received design, based on feedback from our hearing care professional partners,” Ramirez added. “In particular, Styletto X now comes with exchangeable receivers to treat a wider range of hearing loss and enable more patients to benefit from this one-of-a-kind device.”
A New Era of Wearability and Autonomy
Signia is “the first hearing aid brand” to incorporate Qi wireless charging technology into a hearing aid charging case. With this technology, wearers can simply place the Styletto X pocket-sized charging case on a charging pad in cafés, restaurants, or cars, instead of having to plug it into the charging port. Styletto X can be fully charged in only four hours to provide a full day’s wearing, including five hours of streaming.3
The Signia Assistant can help hearing care professionals by leveraging artificial intelligence to help support patients, 24/7, with text-based dialogue, instant sound adjustments, and how-to-videos to answer handling questions.
Remote Fitting and Service Options
With Signia’s new Remote Care solution, hearing care professionals and hearing aid wearers can benefit from flexible fitting and service options via TeleCare, “the first full, live remote fine-tuning solution in the industry,” according to the company.
This hearing solution is available now in performance levels 7, 5, 3, 2, 1 and sDemo and in the contemporary color combinations Snow White/Rose Gold, Black/Silver, Cosmic Blue/Rose Gold, and in new White or Black.

Starkey Updates Fall Alert Feature in ‘Basic Mode’ for IOS and Android
Starkey hearing aids at the Keynsham hearing centre
Starkey announced that its Thrive Hearing Control app has been updated to enable the Fall Alert feature in the “basic mode” for both iOS and Android versions. This feature was previously only available in “advanced mode.” Using their built-in 3D sensors, Starkey’s Livio Edge AI hearing aids can detect when the wearer falls and send alert messages to selected contacts. This update will “allow hearing healthcare professionals to give even more patients the opportunity to maintain their independence and caregivers peace of mind—which, due to current social distancing practices, is more crucial now than ever before.”
“We find it increasingly important for hearing aid wearers to feel secure in their day-to-day lives,” said Starkey Chief Innovation Officer Dave Fabry, PhD. “Because some Livio Edge AI wearers prefer the easy layout of basic mode, the simplified version of our Thrive Hearing Control app, enabling the Fall Alert feature for them was a vital task for us.”
Unlike other fall-detection devices, which are worn around the neck or on the wrist, Livio Edge AI is reportedly “the world’s first ear-worn, fall-detection device and alert system.” To learn more about Starkey and Livio Edge AI, please click here.

Apple Takes Another Step Toward Hearing Aid Functionality
On Monday, June 22, Apple introduced its latest operating system, iOS14, which includes —among many new features—a substantial move towards its AirPod Pros becoming a hearing-aid-like device. Almost buried as an afterthought at the bottom of Apple’s IOS New Features Preview are identical entries in the “Airpods” and “Accessibility” sections that say:
Headphone Accommodations
This new accessibility feature is designed to amplify soft sounds and adjust certain frequencies for an individual’s hearing, to help music, movies, phone calls, and podcasts sound more crisp and clear.Headphone Accommodations also supports Transparency mode on AirPods Pro, making quiet voices more audible and tuning the sounds of your environment to your hearing needs.
Hmmm…sounds a lot like a basic description of wide dynamic frequency compression (WDRC) or AGC, doesn’t it? Abram Bailey of Hearing Tracker, who broke the news yesterday, stated “This is the extremely exciting part, as it indicates that AirPods can now essentially be used to provide typical hearing aid functionality; applying personalised amplification to make it easier to hear those around you.” Bailey went on to show how the headphone accommodations use a custom audio setup with a listening test that generates an “audiogram” from the Apple Health app that “seems to indicate that the AirPods Pro will be capable of providing a very fine-tuned custom amplification experience, based on the audiogram (pitch-by-pitch hearing abilities) unique to the user.”
It should be acknowledged that Apple has for many years been developing hearing-aid-related features, including Live Listen for hearing aids and cochlear implants in 2014 (and later for AirPods and the Earpods), in addition to speech audiometry and speech-in-noise packages for developers, noise warning apps for its WatchOS, and more. The company sold more than 60 million Airpods in 2019, compared to about 15 million hearing aids worldwide for the entire hearing industry (4.2 million units in the US). Apple’s Wearables, Home and Accessories division had the most significant year-on-year growth for the company last year, with its sales increasing 41% thanks to the Airpod and Apple Watch, and the tech-giant owns an enviable 36.5% of the wearables market, according to CompareCamp. Mind you, this includes the “hearables” market that Nick Hunn predicted earlier this year will reach $80 billion a year by 2025.
As Paul Dybala, PhD, AuD, of AudiologyDesign points out in a recent LinkedIn post about Apple and its threat to the hearing industry, “If none of this impresses you, buy a pair of AirPod Pros and turn on the Active Noise Cancelling feature. Then change them over to Transparency Mode and listen further. Once you wipe your jaw off the floor, continue reading. Take your time, I’ll wait…” However, he then goes on to point out that hearing loss is widely viewed as a healthcare problem that should be addressed by a hearing healthcare professional, as shown in a 2017 survey by a study he did with colleague Brande Plotnick at Healthy Hearing.
**************
As a side-note, I’ve personally tried several of the products and hearing tests available in some of the better PSAPs. As one example, Alango Technology’s BeHear app did an impressive job of replicating an audiogram of my own mild sloping hearing loss and tailoring the sound to suit my preferences. The idea of an app doing this also reminded me of a September 2018 Hearing Reviewarticle by James Jerger, PhD, who—after describing three basic forms of automated audiometry—wrote:
“The most important issue is to catch up with the rest of the automated world…In spite of the many examples of successful automated systems summarised above, I suspect that there will be little further progress in the actual clinical use of automated audiometry of any variety until clinicians become part of the solution. It goes back to their initial educational experience. If the only procedure they learn as students is the manual Hughson-Westlake method on a conventional audiometer, it is unlikely that they will be easily diverted from that familiar path, sophisticated technology notwithstanding. PhD and AuD students—in addition to practicing clinicians—need to understand that automated audiometry can be carried out by less credentialed personnel, resulting in time and cost savings in a clinical setting. It is apparent this testing is moving into the digital/consumer realm [with the link going to Apple’s WDDC 2018 video that includes a demonstration of speech audiometry].
The point is professional hearing healthcare is so much more than automated tests and apps. As Dr Dybala notes in his article, it’s about assessing an often-complex medical problem and applying all of the tools available to tailor an individual solution that works for the patient in all kinds of listening situations, including (and especially) noise. However, as shown by Apple and others, the world of hearables with their automated testing and applied amplification should help millions of consumers make their first moves toward professional hearing care.

CEVA, Inc (NASDAQ: CEVA), a licensor of wireless connectivity and smart sensing technologies, and Bragi GmbH, a technology company based in Munich, Germany, announced a strategic collaboration to drive a new class of hearable devices where the user experience is “customizable via the industry’s first hearable app store.” Target devices include headsets, hearing aids, True Wireless Stereo (TWS) earbuds, and a host of other smart audio devices for the consumer and the smart home.
According to the companies’ announcement, the partnership takes advantage of the low power, CEVA-BX DSP architecture, along with its LLVM compiler and Eclipse based development tool chain, and Bragi 4, a newly defined operating system (OS) specialized for hearables. In conjunction with Bragi 4 OS, Bragi’s patented commercial app store will “help enable technology partners and experts to offer software apps and services such as voice activation, voice biometric, audio post processing, and music services.” These software packages can be licensed and downloaded directly to devices based on this architecture, allowing individuals to personalize their hearables user experience. CEVA will also offer a range of its value-added software via the Bragi app store, including ClearVox for noise reduction, WhisPro for speech recognition, MotionEngine for sensor fusion, and the SenslinQ framework for contextual awareness.
“Imagine buying headphones that adapt according to the needs of the user. Purchase noise-canceling software just before boarding a plane,” said Nikolaj Hviid, Founder and CEO of Bragi. “Encrypt communication data for sensitive business conversations. Discover that you hear better with voice amplification through try-to-buy offers. On business travel, use your headphones to translate from Chinese into English. Add a feature that alerts someone if your headphones detect you’ve fallen over. The possibilities are endless.”
Through this collaboration, “hearables and other smart audio devices will transform in the same way as the mobile phone industry in the ’00s, by replacing single-purpose feature products with flexible products capable of adapting their functionalities to the users through post-purchase apps and services.”
“Our collaboration with Bragi brings a game-changing approach to the design of hearables and other audio devices, where the user experience can be adapted, instantaneously,” said Moshe Sheier, Vice President of Marketing at CEVA. “Our CEVA-BX audio DSPs, voice processing and motion sensing software, and SenslinQ context-aware framework perfectly complement Bragi’s OS and unique capabilities in providing a direct channel for OEMs and ODMs to offer a customizable user experience to consumers through enhanced software and services.”

New report in deafness therapy has been reported by a new scientific paper. Here at the Keynsham hearing centre are keen to keep up with the latest information to keep our patients informed.
High-pressure Oxygen Therapy May Help Treat Sudden Deafness, Says ‘JAMA’ Study
BottomLine: The addition of hyperbaric oxygen therapy (where patients receive pure oxygen in a pressurised chamber) to standard medical treatment was associated with an improved likelihood that patients who experience sudden deafness might recover all or some of their lost hearing, JAMA Network announced on its website. Sudden deafness, also known as sudden sensorineural hearing loss (SSNHL), is hearing loss that happens within a few days and often has no identifiable cause. This study combined the results of 19 studies, including three randomised clinical trials, and suggests a greater benefit of adding the hyperbaric oxygen therapy may be associated with those patients who have severe to profound hearing loss and who failed to recover after standard medical treatment. A limitation of this study is that because a substantial number of patients with SSNHL will spontaneously recover, the benefits of treatment may not have been accurately evaluated.
