Phonak Wins Three Red Dot Product Design Awards
Phonak hearing aids are available at the Henley Hearing Clinic.
Phonak, a global provider of hearing aids and wireless communication solutions, has been honored with three international Red Dot Awards for excellence in product design, the company announced. The product award winners include: Virto B-Titanium, said to be “the world’s first” mainstream titanium custom hearing aid; Audéo B-Direct, a Bluetooth®* hearing aid that is designed to directly connect to both a cell phone** and TV; and EasyView Otoblock, a product for hearing care professionals that is designed to allow for deeper ear impressions. The winners were celebrated at the Red Dot Gala earlier this month in Essen, Germany.
“Three Red Dot Award winners in one year is proof of what happens when you combine Phonak’s dedication to superior product design with a neverending quest to push the limits of innovation,” said Thomas Lang, senior vice president at Phonak. “Receiving honors for the Virto B-Titanium and EasyView Otoblock is a tribute to the amount of research and development Phonak devotes to producing the most cosmetically appealing and highest quality custom products on the market. Meanwhile, the awards for the revolutionary Audéo B-Direct keep on adding up!”
According to Phonak, the Virto B-Titanium is “the world’s first mainstream” custom hearing aid made of premium medical-grade titanium. It was designed to combine the benefits of titanium including superior strength and an extra light weight with the latest in 3D printing technology.
With the Audéo B-Direct, hearing aid wearers can answer or reject a phone call and talk completely hands-free by pressing the push button on their hearing aid. Meanwhile, the optional TV Connector uses proprietary AirStream™ technology to help connect wearers to their favorite TV programming for an immersive audio experience.
The EasyView Otoblock is designed to give hearing care professionals the ability to take deeper ear impressions by allowing “full visualization” of the eardrum, according to the company. Made from the seal of a Phonak Lyric™, the EasyView Otoblock attaches to existing otoscopes and speculas and is designed to provide better vision and light during Otoblock placement. It’s compatible with standard impression-making materials and stays on the impression during the scanning process, according to the company’s announcement. This may result in an average of 6mm more canal length information.
“I want to congratulate the award winners sincerely on their wonderful success in the Red Dot Award: Product Design 2018,” said Professor Dr Peter Zec, founder and CEO of the Red Dot Award. “Success in the competition is proof of the good design quality of the products and once again shows that companies are on the right path. When I speak about good design, I am referring to more than just an attractive product. All of the products are characterized by outstanding functionality. This demonstrates that the designers have understood their clients and their needs.”

Samsung Announces Hearing Loss Detection App and New Initiative
According to the World Health Organization (WHO), over 5% of the world’s population—or 466 million people—have disabling hearing loss. In Argentina, hearing impairment constitutes 18% of the existing disabilities according to Info LEG—86.6% of which experience hearing difficulties; 13.4% are deaf.
While those diagnosed with hearing loss can take necessary actions for their individual cases—taking preventive measures to avoid total deafness, getting hearing aids, learning sign language, etc—those who do not know what’s happening to them are subject to a more frustrating experience. This is especially true for children who may lose the chance to develop their cognitive skills and pursue higher education.
Using Technology to Bridge the Gap
uSound for Samsung is an initiative designed to bring technology to people with hearing loss—to help detect the risk of hearing loss and thus improve their quality of life in such essential aspects as communication and education, the South Korea-based company announced.
uSound Test is a free application that is designed to allow users to detect their hearing loss risk. According to the company’s press release, the app reproduces pre-calibrated sounds that users give feedback to. It then compares these results with its database, with the app reportedly detecting specific frequencies the user may have difficulty hearing. uSound Test is designed to analyze the auditory curve that results from the whole test to help determine the degree of hearing loss risk.
uSound for Samsung reportedly issues a report with the results, designed as “a risk indicator,” according to Samsung. Since the test is not designed to be a medical diagnosis, the app recommends users contact hearing health specialists when necessary.
Cynthia Giolito, senior manager, corporate citizenship, Samsung Electronics Argentina, said: “uSound for Samsung reinforces our mission to offer technology with a purpose that improves quality of life. We are very proud to embark on this path and we hope to have solid results that will promote hearing accessibility in more places.”
Through uSound for Samsung, the company hopes to use its technology and resources to:
- Raise awareness about hearing loss and improve public policies;
- Avoid irreversible damage to hearing organs;
- Encourage learning and cognitive development for children;
- Develop speech and facilitate social inclusion;
- Contribute to a more egalitarian society.
Working with the Community
The Government of Jujuy will provide resources and workspaces for the hearing loss-detection campaign, according to Samsung. uSound will continue to help improve hearing experiences with its products, including the aforementioned test and an app that turns the cell phone into an auditory assistant**, according to the company’s announcement. Samsung Electronics will provide the necessary technology to carry out a first pilot test of uSound Test in health centers across Jujuy and will financially support the project.
Governor Gerardo Rubén Morales, Jujuy Province, said: “It is a pleasure to accompany uSound, a company from Jujuy, take on its challenges. With the support of Samsung, this project will impact thousands of people with hearing problems. It is great that this project started in Jujuy. We hope it can be replicated throughout Argentina and in other countries—technological innovation knows no boundaries.”
As a team, the Government of Jujuy, uSound, and Samsung Electronics Argentina will help give a larger part of the Argentine community access to tools to potentially change lives through the use of technology.
Ezequiel Escobar, CEO and co-founder of uSound, said: “We witnessed a truly historic opportunity for our company and for Jujuy. This plan, using our technologies, will benefit many people from Jujuy and has the potential to expand to help many more people around the world. We are talking about a huge impact that grows even more with the support from Samsung and the Ministry of Health of Jujuy.”
Samsung has been preparing for entry into the hearing care market for several years; Hearing Review reported that the company filed an April 2013 patent for a “small hearing aid.” In 2015, Samsung placed a $13.9 million order for hearing aid amplifiers driven, according to a BusinessKorea article, by Vice Chairman Lee Jae-yong’s interest in what it called “mobile health care.” More recently, SamMobile reported in 2016 that Samsung applied for trademark registration of the term Earcle in South Korea, and that its application referenced hearing aids. Additionally, a Samsung device described as a “Samsung Bluetooth Hearing Aid” with the model number SM-R790, reportedly surfaced at the Bluetooth Special Interest Group’s (SIG) database.

Newsreader Lewis Vaughan Jones makes debut wearing hearing aid.
A newsreader who suddenly lost the hearing in his left ear, has received messages of support after his first appearance on air with a hearing aid.
Lewis Vaughan Jones, 37, feared his career presenting the news on the BBC and ITN was over after doctors told him the hearing loss was permanent.
“That was the darkest moment,” he told BBC Radio 5 live.
He also spoke of his embarrassment in social situations and the difficulties of coming to terms with a hearing aid.
Vaughan Jones had good hearing all his life until he got a cold several months ago and couldn’t hear in one ear.
Doctors found his left eardrum was no longer working and the nerve which takes sound to the brain had given up, he told BBC Breakfast.
When they told him the sudden hearing loss and the tinnitus were permanent, he walked out of hospital “completely bamboozled”, he added.
The charity Action on Hearing Loss says about 11m people in the UK have some form of hearing loss, and 2m use hearing aids. It estimates that there are about 6.7m people who could benefit from hearing aids.
Before being fitted with a hearing aid, Vaughan Jones said his situation had left him frustrated and embarrassed.
“There’s only so many times you can interrupt. You feel embarrassed so you withdraw,” he said.
He also described how he would smile and nod along when spending time with friends and family, feeling unable to engage and as though he was missing out.
His hearing aid, he said, has been a massive help, allowing him to return to work.
His return to screen, however, was a noisy one as he can hear the director and correspondents through an earpiece in his right ear and an amplified, distorted version of his own voice through the hearing aid in his left.
The brain should learn to quieten down that distortion, he said.
Getting used to wearing a hearing aid has not come easy.
“I was self-conscious about it. My hair is slightly longer so that’s a reflection that I might have been trying to hide it,” he adds.
Now back on air, he wants to show everyone he is wearing one.
“There’s no logical reason why I shouldn’t wear my hearing aid on air and feel good about it,” he said.
Some took to Twitter to agree.
Robbie M said he started wearing two hearing aids five years ago after finding he was unable to hear in meetings. He advised Vaughan Jones to “wear them with pride,” adding: “Quality of life over people’s thoughts every time.”
Nikki Magrath said: “Great to hear you talk about SSHL [Sudden Sensorineural Hearing Loss] today. I know just how it feels. Has happened twice – once with full recovery.”
Heading a Football May Be Linked to Increase in Balance Problems
Soccer players who head the ball more often may be more likely to have balance problems than players who do not head the ball as often, according to a preliminary study released today that will be presented at the American Academy of Neurology’s (AAN) Sports’ Concussion Conference in Indianapolis July 20 to 22, 2018, the AAN announced on its website.
“Soccer headers are repetitive subconcussive head impacts that may be associated with problems with thinking and memory skills and structural changes in the white matter of the brain,” said study author John Jeka, PhD, of the University of Delaware in Newark, Del. “But the effect of headers on balance control has not been studied.”
For the study, 20 soccer players recruited from the community in Newark took a balance test where they walked along a foam walkway with their eyes closed under two conditions: with galvanic vestibular stimulation (GVS) and without GVS. For GVS, electrodes placed behind each ear stimulate the nerves that send messages from the balance system in the inner ear to the brain. So the stimulator can make you feel like you are moving when you are not. In this case, it made participants feel like they were falling sideways.
The soccer players, who had an average age of 22, also completed questionnaires about how many times they had headed the ball during the past year. The number of headers over a year for each participant ranged from 16 to 2,100, with an average of 451 headers. Those numbers were calculated by asking participants for the average number of headers during a practice and game, the average number of practices and games per week, and the average number of months per year that the player participated.
The study found that the players with the largest number of headers had the largest balance responses to GVS in both foot placement and hip adduction during the walking test, which indicated that they had vestibular processing and balance recovery problems. Researchers found for every 500 headers, foot placement response increased about 9 millimeters and hip adduction response increased about 0.2 degrees.
“Soccer players must have good balance to play the game well, yet our research suggests that headers may be undermining balance, which is key to all movement, and yet another problem now linked to headers,” said study author Fernando V. Santos, PT, of the University of Delaware. “It is important that additional research be done to look more closely at this possible link with balance and to confirm our findings in larger groups of people.”
A limitation of the study was that participants relied on memory when reporting how many times they headed the ball. The study was supported by the National Institutes of Health (NIH).

Tinnitus Relief app makes living with tinnitus easier
Henley Hearing Clinic, News:
An international study from 2012 found that 15% of the global population experience permanent tinnitus but many more are affected by temporary tinnitus. A Danish study, also from 2012, with 14,000 participants found that 27% of those in the study experienced either temporary or permanent tinnitus. In other words, more than one quarter of the Danish population are affected tinnitus.
But despite a lot of research on the topic, there is still a lot to learn about tinnitus. According to Chief Physician Ture Andersen at Odense University Hospital in Denmark, tinnitus is often a symptom of damage to the inner ear. Tinnitus is not a disease, but can be a symptom of a disease or an impaired auditory system. It is defined as the perception of noise or ringing in the ears when no external sound is actually present. The sounds are most commonly described as ringing, whistling, wheezing, buzzing or humming, but can be described in many other ways. A large Swedish study showed that excessive noise at work and in other environments results in fatigue, headaches and ultimately impaired hearing or tinnitus. Another study, from France, shows that only one in 123 people with tinnitus do not have a hearing impairment.
Eva Jensen, who lives in Greve, Denmark, fits in well to these statistics. With a moderate to severe hearing loss, Eva can’t hear much without her hearing aids and she experiences tinnitus.
“What does your tinnitus sound like?” I asked Eva. She explained that it is a constant buzzing sound, which lies somewhere in the middle of the pitch spectrum. “I think it developed at my work where there was a lot of noise,” says Eva. In 2006 she stopped working as an Educational Assistant in a nursery because of a back injury and since then she has suffered from constant back pain.
“It was only when I stopped working that I started thinking about my tinnitus. My husband was still working so I was at home alone where it was completely quiet and I became more aware of the ringing in my ears.” She experiences it all day, especially when she takes off her hearing aids in the evening. “Since my injury I have the TV on constantly – it helps me think of something other than my back pain,” says Eva.
Eva’s experience with Relief app
“It’s really great to be able to use the app when my tinnitus is driving me crazy. If you are strongly affected by tinnitus, I would definitely recommend this app. There are so many possibilities with creating your own soundscapes, you can always find a sound that’s comfortable. There is no doubt that I’m going to keep it on my phone, so I can get help when my tinnitus it really bothering me,” says Eva with a smile.
The idea of helping people focus on something other than the pain, or in this case tinnitus, is the basic concept of a new app made by the hearing aid manufacturer GN Hearing. The free app is called ReSound Relief and offers a combination of audio therapy and relaxation exercises. My editorial team and I tested the app, which offers some new and unique features compared to other apps we have tried. One very smart feature of the app is that it allows you to create your own soundscapes.
Relief allows you to combine a variety of familiar sounds such as birdsong or bubbling water with music and other therapeutic nature sounds. The ability to combine sounds, offers an almost endless amount of possibilities. This sound mixing feature allows you to mix five different sounds and you can individually adjust the volume of each sound.
After downloading the app, you can listen to music on your smartphone as usual, and if you use wireless hearing aids or headphones, you can stream directly through them. The ReSound Relief app also contains a feature called MyRelief that keeps a record of how you use the app and which sounds you have used the most. It creates a personalized plan and allows you to track your progress, much like an exercise app. “When we were developing the concept of this app, we analyzed the market for other tinnitus apps and found that mostof them just use sounds as a distraction. Very few actually guide the user through the tinnitus management process. Tinnitus management for many is more than just playing a sound.
The idea of MyRelief is that you can use it as part of the treatment provided by a Hearing Care Professional. Because MyRelief keeps a record of your use, it provides useful information that a Hearing Care professional can use as part of tinnitus counseling” says Michael Piskosz, Senior Audiologist at GN Hearing.
The app gives you some great tools to help you with your tinnitus.
Avoid a vicious spiral
Worldwide, around 700 million people experience tinnitus. Around two thirds of them have mild to moderate tinnitus. People in the last third with more severe tinnitus can even experience feelings of desperation and hopelessness. International studies show that only about 3-5% of people seek help, so many people just try to live with tinnitus without any support. “In the United States, 70-80% of the population have a smartphone, and because we know that many people are desperately searching for help, we made this app. In most cases, the app will be beneficial. In addition to the distracting sounds there is also therapeutic support,” says Michael Piskosz. “ReSound Relief includes relaxation exercises and techniques for dealing with the tension and stress that tinnitus can cause. If you are extremely affected by tinnitus, the app alone will not be enough but it is a very useful tool and a great first step for people seeking help with tinnitus.”
This strategy is supported by a study by Professor Ture Andersen from Odense University Hospital. “Unfortunately, the more emotionally you react to your tinnitus, the more the tinnitus signals will pass through the hearing center in your brain. If you respond by getting irritated or with stress or anxiety, it can actually make you more aware of the tinnitus sounds. You may end up getting into a “vicious cycle” where your tinnitus ends up controlling you. It’s important to learn how to avoid this. One way is by training yourself not to respond to the tinnitus sounds. This way, the brain will filter out the noise signals to a large extent before reaching the hearing center. Then you’ll only hear a weak sound in the background, a light soundscape that makes it less distracting.” The study also shows that music can help. The volume of the music should not be particularly high – it’s not about covering up the sound of tinnitus with a louder sound – but about focusing your attention on the music and away the tinnitus.
“In some cases, when you use audio therapy to get relief from your tinnitus, the focus on it can increase,” explains Michael Piskosz. “Many people believe that this is due to the introduction of the technology to help with the tinnitus. Often times, people monitor their tinnitus more, to see if the technology is helping. It’s similar to when someone gets a new pair of shoes. At first, they are very aware of the shoes, and getting used to the fit. But, with time, they adjust and acclimate. Typically, users will find that the focus on tinnitus will be reduced over-time by using an app like ReSound Relief.”

Researchers Identify New Type of Vertigo, According to Study Published in ‘Neurology’
With vertigo, people have episodes of dizziness that can last from minutes to days. Vertigo can be caused by serious conditions, such as tumors, or conditions that are fairly benign, such the inner ear disorder Meniere’s disease. But for some people, no cause can be found.
In this new study, neurologists have identified a new type of vertigo where treatment may be effective.
“These conditions can be difficult to diagnose and quite debilitating for people, so it’s exciting to be able to discover this new diagnosis of a condition that may respond to treatment,” said study author Ji-Soo Kim, MD, PhD, of Seoul National University in Seongnam, South Korea.
To diagnose this new condition, the person sits in a dark room and the examiner moves the patient’s head forward and then the head is shaken horizontally for about 15 seconds. Then the patient opens his or her eyes and a video recording is taken of eye movements. The neurologists discovered that after the test, people with this new condition had eye movements called nystagmus that lasted longer than for other people. The new condition is called recurrent spontaneous vertigo with head-shaking nystagmus.
Among 338 people with vertigo with no known cause, 35 had this new condition and were included in the study. The participants had attacks of vertigo ranging from two or three times a week to once a year. They also experienced nausea or vomiting, headaches, and intolerance of head motions during the attacks.
The participants were compared to 35 people with other conditions that can cause vertigo, such Meniere’s disease, vestibular migraine, and vestibular neuritis. The test measured the time constant, or the time that represents the speed with which the reflexive eye movements can respond to change. For those with the new condition, the time constant during the primary phase of the nystagmus was 12 seconds, while it was six seconds for those with Meniere’s disease and five seconds for those with vestibular neuritis and vestibular migraine.
The neurologists also found that people with the new type of vertigo were more likely to have severe motion sickness than those with other types of vertigo.
A total of 20 of the 35 people with the new type of vertigo who had frequent attacks and severe symptoms were given preventive medication. About one-third of those had partial or complete recovery with the new medication. During the long-term follow-up of an average of 12 years after the first symptoms for 31 participants, five reported no more attacks, 14 said their symptoms had improved, and only one said symptoms had gotten worse.
Kim said that people with this condition may have a hyperactive mechanism in their vestibular system that helps the brain respond to movement of the body and in the environment.
“It’s possible that the vertigo occurs when this unstable mechanism is disrupted by factors either within the person’s body or in their environment,” Kim said.
The study was supported by the National Research Foundation of Korea.

Brainwave Abnormality Could Be Common to Parkinson’s Disease, Tinnitus, Depression
Vanneste and his colleagues—Dr Jae-Jin Song of South Korea’s Seoul National University and Dr Dirk De Ridder of New Zealand’s University of Otago—analyzed electroencephalograph (EEG) and functional brain mapping data from more than 500 people to create what Vanneste believes is the largest experimental evaluation of TCD, which was first proposed in a paper published in 1996.
“We fed all the data into the computer model, which picked up the brain signals that TCD says would predict if someone has a particular disorder,” Vanneste said. “Not only did the program provide the results TCD predicted, we also added a spatial feature to it. Depending on the disease, different areas of the brain become involved.”
“The strength of our paper is that we have a large enough data sample to show that TCD could be an explanation for several neurological diseases.”
Brainwaves are the rapid-fire rhythmic fluctuations of electric voltage between parts of the brain. The defining characteristics of TCD begin with a drop in brainwave frequency—from alpha waves to theta waves when the subject is at rest—in the thalamus, one of two regions of the brain that relays sensory impulses to the cerebral cortex, which then processes those impulses as touch, pain, or temperature.
A key property of alpha waves is to induce thalamic lateral inhibition, which means that specific neurons can quiet the activity of adjacent neurons. Slower theta waves lack this muting effect, leaving neighboring cells able to be more active. This activity level creates the characteristic abnormal rhythm of TCD.
“Because you have less input, the area surrounding these neurons becomes a halo of gamma hyperactivity that projects to the cortex, which is what we pick up in the brain mapping,” Vanneste said.
While the signature alpha reduction to theta is present in each disorder examined in the study—Parkinson’s, pain, tinnitus, and depression—the location of the anomaly indicates which disorder is occurring.
“If it’s in the auditory cortex, it’s going to be tinnitus; if it’s in the somatosensory cortex, it will be pain,” Vanneste explained. “If it’s in the motor cortex, it could be Parkinson’s; if it’s in deeper layers, it could be depression. In each case, the data show the exact same wavelength variation—that’s what these pathologies have in common. You always see the same pattern.”
EEG data from 541 subjects was used. About half were healthy control subjects, while the remainder were patients with tinnitus, chronic pain, Parkinson’s disease, or major depression. The scale and diversity of this study’s data set are what set it apart from prior research efforts.
“Over the past 20 years, there have been pain researchers observing a pattern for pain, or tinnitus researchers doing the same for tinnitus,” Vanneste said. “But no one combined the different disorders to say, ‘What’s the difference between these diseases in terms of brainwaves, and what do they have in common?’ The strength of our paper is that we have a large enough data sample to show that TCD could be an explanation for several neurological diseases.”
With these results in hand, the next step could be a treatment study based on vagus nerve stimulation—a therapy being pioneered by Vanneste and his colleagues at the Texas Biomedical Device Center at UT Dallas. A different follow-up study will examine a new range of psychiatric diseases to see if they could also be tied to TCD.
For now, Vanneste is glad to see this decades-old idea coming into focus.
“More and more people agree that something like thalamocortical dysrhythmia exists,” he said. “From here, we hope to stimulate specific brain areas involved in these diseases at alpha frequencies to normalize the brainwaves again. We have a rationale that we believe will make this type of therapy work.”

Q & As: This Week’s Top Selections
Q: How long should the battery last after a full charge? How much does Bluetooth activity affect this? —Brent Spehar
A: This is a great and very important question. Battery life is dependent on several factors including the amount of capacity of the battery, how fast the hearing aid drains the current, and the wear behaviors and habits of the user.
I like to use the example of an automobile. How many gallons of gas does the fuel tank hold or, for hearing aid batteries, how many mAh capacity is in the battery? How many miles per gallon does the car use or how many mA does the battery drain both when streaming and not streaming? And, finally, is the car driven on the highway or in the city and is the air conditioner on or off? Or, for hearing aids, how many hours per day does the hearing aid stream? Does the hearing aid use 2.4 GHz streaming or does it is use NFMI with an intermediate device that has its own battery? And, what features are turned on or off on the hearing aid?

Once you answer these questions, you can figure out “how long the battery will last after a full charge.” I gave some example calculations in the HRarticle: The Changing Landscape of Hearing Aid Batteries (Hearing Review, October 31, 2017).
Please note a factor we have learned in our electronics’ lab. Not all hearing aids are the same. Some 2.4 GHz products have current drains averaging 4.8-5.0 mA when streaming while other 2.4 GHz products using lower power Bluetooth will drain the battery at 3.0-3.4 mA while streaming. Some 2.4 GHz products when not streaming may have battery drains of 1.8-2.0 mA, while some of the newer products with bilateral beam-forming may drain the battery at 2.3-2.5 mA when not streaming.
The key is to know your products and know your patient’s listening habits. This is critical to good counseling.
Q: Is the life of the hearing aid circuit reduced as a result of using the rechargeable system? It did happen when [a previous model of hearing aid] were rechargeable. —Anjan Muhury
A: The ZPower Rechargeable System has been thoroughly evaluated by the hearing aid manufacturers and there is no indication that the system will have a negative effect on the life of the hearing aid circuit. The ZPower silver-zinc battery is designed to mimic the performance of traditional zinc-air batteries and is transparent to the DSP of the hearing aids. Extensive studies of hearing aids using the ZPower System also show the system including the ZPower silver-zinc batteries have no impact on the electrophysiologic performance of the hearing aids. Therefore, the ZPower System will not have a negative impact on the hearing aid circuitry or performance.
Previous Q & A’s
Q: What’s a realistic time frame for a rechargeable hearing aid battery to last?
A: Rechargeable silver-zinc batteries last about a year. They are removeable and therefore easily replaced. It is recommended that rechargeable silver-zinc batteries are replaced once a year by a hearing care professional.
Li-ion batteries are sealed within the hearing aid, and are usually removable only by the hearing aid manufacturer. They last approximately 4 to 5 years.
A: When the hearing aids are put on the charger, the charger will check to see what type of battery is in the hearing aid. If the charger detects a disposable zinc air battery, the lights on the charger will turn red. If the charger detects a silver-zinc battery, the lights on the charger will start blinking green; once the battery is fully charged, the lights will turn solid green.
Q: Can my patients overcharge a ZPower battery if they leave it in the charger for too long?
A: The batteries will not overcharge if left in the charger. It is a best practice to put the hearing aids back on the charger when the hearing aids are not being worn during the day. This will keep the hearing aids turned off and the batteries charged. For long-term storage, if batteries will not be used for over 2 weeks, the rechargeable batteries should be removed from the hearing aids and stored in a location where they will not touch each other or other metal objects.
Q: What happens when the silver-zinc rechargeable battery is getting low on power?
A: The hearing aid wearer will hear the low battery warning. Once the low-battery warning occurs or once a hearing aid shuts off due to a low battery condition, the battery door should not be opened and closed to reboot the hearing aid. Rebooting after the low battery warning can override the smart circuitry in the battery door into believing it has a traditional disposable battery installed and, although the hearing aid will continue to work for a short period, it may over-discharge the battery. If a low-battery warning from the hearing aids is received, the hearing aids should be placed in the charging base for charging or the batteries should be replaced with non-rechargeable batteries. The rechargeable batteries should not be stored with metal objects such as keys or coins.
Q: How often should the batteries be charged?
A: The batteries should be fully charged every night. Once the hearing aids are finished charging, the indicator lights turn from blinking green to solid green. A full charge may take up to 7 hours—the charge time varies based on how much the battery was depleted during the day. Do not try to extend battery life by charging every other day, as this increases the chances of depleting the battery. A fully depleted battery will take longer to charge and may not fully charge in time for next use.
Q: What happens if the hearing aid wearer forgets to charge the battery at night?
A: They can use a disposable zinc-air battery until it is convenient to re-charge the batteries—ideally the rechargeable batteries should be charged the next night. The rechargeable silver-zinc batteries are a gold color, so they will not be mixed up with zinc-air disposable batteries. The rechargeable batteries should be stored in a safe place and should not be stored with metal objects such as keys or coins.
