Researchers Identify Gene Associated with Age-related Hearing Loss
An international group of researchers, led by Ronna Hertzano, MD, PhD, associate professor, Department of Otorhinolaryngology-Head & Neck Surgery, at the University of Maryland School of Medicine (UMSOM), and Michael Bowl, PhD, program leader track scientist, Mammalian Genetics Unit, MRC Harwell Institute, UK, have identified the gene that acts as a key regulator for special cells needed in hearing.
The discovery of this gene (Ikzf2) will help researchers better understand this unique type of cell that is needed for hearing and potentially develop treatments for common age-related hearing loss, UMSOM announced.
Bucks hearing aids
“Outer hair cells are the first inner ear cells lost as we age,” said Hertzano, whose research will be published in the journal Nature. “Age-related hearing loss happens to everyone. Even a 30-year-old has lost some of the outer hair cells that sense higher pitch sounds. Simple exposure to sound, especially loud ones, eventually causes damage to these cells.”
The inner ear has two kinds of sensory hair cells required for hearing. The inner hair cells convert sounds to neural signals that travel to the brain. This compares to outer hair cells, which function by amplifying and tuning sounds. Without outer hair cells, sound is severely muted and inner hair cells don’t signal the brain. Loss of outer hair cells is said to be the major cause of age-related loss of hearing.
About the Research
Hertzano’s group, in collaboration with Ran Elkon, PhD, senior lecturer, Department of Human Molecular Genetics and Biochemistry, Sackler Faculty of Medicine in Tel Aviv, Israel, took a bioinformatics and functional genomics approach to discover a gene critical for the regulation of genes involved in outer hair cell development. Bowl’s group studied mice from the Harwell Aging Screen to identify mice with hearing loss. Bowl identified mice with an early-onset hearing loss caused by an outer hair cell deficit. When the two groups realized that they were studying the same gene, they began to collaborate to discover its biological function and role in outer hair cell development. The gene is Ikzf2 gene, which encodes helios. Helios is a transcription factor, a protein that controls the expression of other genes. The mutation in the mice changes one amino acid in a critical part of the protein, which impaired the transcriptional regulatory activity of helios in the mice.
Micro-suction wax removal Bucks
To test if helios could drive the differentiation of outer hair cells, the researchers introduced a virus engineered to overexpress helios into the inner ear hair cells of newborn mice. As a result, some of the mature inner hair cells became more like outer hair cells. In particular, the inner hair cells with an excess of helios started making the protein prestin and exhibited electromotility, a property limited to outer hair cells. Thus, helios can drive inner hair cells to adopt critical outer hair cell characteristics.
Funding for the research was provided by Action on Hearing Loss UK, the National Institute on Deafness and Other Communication Disorders (NIDCD) at the National Institutes of Health, and the Department of Defense (DOD).
As Professor Steve Brown, PhD, director, MRC Harwell Institute, said, “The development of therapies for age-related hearing loss represents one of the big challenges facing medicine and biomedical science. Understanding the genetic programs that are responsible for the development and maturation of sound-transducing hair cells within the inner ear will be critical to exploring avenues for the regeneration of these cells that are lost in abundance during age-related hearing loss. The teams from the University of Maryland and the MRC Harwell Research Institute have given us the first insights into that program. They have identified a master regulator, Ikzf2/helios, that controls the program for maturation of outer hair cells. Now, we have a target that we can potentially use to induce the production of outer hair cells within damaged inner ears, and we are one step closer to offering treatments for this disabling condition.”

New type of hearing aid for Buckinghamshire
We are always on the look out for new hearing tech at the Chalfont hearing centre. Today we are posting a review on the newly available Sivantos hearing aids that buck the trend of how hearing aids should look like.
Chalfont hearing news:
Sivantos Launches New Form Factor with Signia Styletto SLIM RIC
Why should a hearing aid looklike a hearing aid? That’s the question Sivantos engineers asked themselves when designing the new Signia Styletto receiver-in-the-canal (RIC) hearing aid which is being launched today. Styletto is a rechargeable SLIM RIC that features a contemporary design and breaks the mold of traditional behind-the-ear (BTE) hearing aids by taking advantage of how its lithium-ion battery technology doesn’t need to conform to the traditional size and shape of a button cell. The new RIC, which uses the Signia Nx platform with Own Voice Processing (OVP), also comes with an extremely small charger which offers fast charging solutions as well as three full charges on the go.
Bucks hearing tests
“There are people who look at a hearing aid and really don’t see it matching their style,” says Eric Branda, AuD, director of product management at Sivantos Inc, Piscataway, NJ. “We see all these people wearing large Bluetooth headsets flashing on their ears—huge devices on their ears—and yet [the hearing industry has] struggled to get them to adopt hearing aids, and I think it really comes down to the fact that we keep asking them to wear what looks like a hearing aid.”
Stylistic freedom by thinking outside the button cell. In terms of the history of hearing aids, Branda points out that, going all the back to the original body-worn devices and moving into today’s CIC and RIC devices, hearing aid sizes and styles have been dictated by the size and shape of button cell batteries. Although lithium-ion rechargeable batteries have also been built in this coin design, they’re not restricted to it—as demonstrated by the new Styletto SLIM RIC. Instead, it departs from the traditional coin cell look by using a slim pin design to create a new form factor.
“With today’s battery technology, we can take a new approach,” says Branda. “Rather than being discreet by being invisible, we can be discreet and drive acceptance withvisibility, which is a novel approach for people with hearing loss.”
Differentiating a hearing aid practice by appealing to different wearers. With its slim, elegant design that harkens to other high-tech product categories, Styletto provides a new option for those who might be put off by the traditional look of a hearing aid. In a US study of 500 mostly new users (92%) with moderate hearing loss, Sivantos found that when participants were given a choice between traditional BTE (Motion) or RIC (Pure) designs, or given the option of no hearing aid at all, more than half (57%) opted for the RIC, 19% selected the BTE, while almost one-quarter (24%) chose to go without a hearing aid. However, when the new Styletto was inserted into the study as an option, 90% of the participants selected a hearing aid: 65% of the study participants selected the SLIM RIC design, while about equal percentages opted for either the BTE and RIC (13% and 12% respectively), and only 10% chose no hearing aid at all.
Buckinghamshire ear wax removal
Similarly, when consumers looked at a simulated practice storefront window with a standard portfolio, only about 16% of the participants chose an offering without Styletto, while 84% of people chose an offering with the new aid.
Branda says that this indicates Styletto provides dispensing professionals with a new product that aligns more closely with patients’ style and view of themselves. “It may come down to the fact that people know what a hearing aid looks like,” he says. “But, when they see Styletto, they think ‘I can see myself wearing that and it doesn’t make me look like a hearing aid wearer.’”
Portable rechargeability for the wearer. The Styletto’s recharging case is very small, and reportedly offers 19 hours of full-day use with a 3-hour charge. If the wearer forgets to charge the device, they can drop it into the charger for 30 minutes and be able to use the device for 5 hours, says the company. The charger also carries three additional full charges. Thus, if the user starts out in the morning with a full charge and the charger is fully charged, they actually have four days of portable battery capacity available to them, according to Sivantos. The charger also contains an LED indicator to view the status of the charging, as well as an automatic on/off feature which means that the charger can serve as the primary carrying case.
Nx technology. The Styletto hearing aid uses Signia Nxsignal processing which is designed to emphasize a natural experience using Sivantos’ Own Voice Processing (OVP) technology. Signia’s ear-to-ear wireless (Ultra HD e2e®) is used in OVP as well as the hearing aid’s Narrow Directionality for a more natural sound quality and better speech intelligibility in noise. The wireless technology also enables the device’s Twin Phone capabilities, which allows the wearer to place the phone up to the ear, obtain the acoustic signal, and then the hearing aid wirelessly sends the signal to the opposite ear for binaural advantage during the phone call.
The sleek instrument does not have push-buttons or a volume control. For those who want more control, the touchControl®App is a downloadable cell phone application that allows for the changing of volume, programs, and directionality. Similarly, miniPocket™, which resembles a keychain type remote control, allows for volume and program changes.
Styletto is available in all three of the Nx performance levels (7/5/3) and uses a Size M (60/119) receiver in lengths 2 and 3. The device is applicable for people with mild to moderately severe losses (60 dB gain).

Widex Announces New Insights into EVOKE Hearing Aid’s AI Function
Widex announced the first data gathered from the WIDEX EVOKE™ hearing aid, which is said to achieve “a new level of Artificial Intelligence (AI)” through machine learning, and is helping to bring new insights into how users are taking control of their sound environment to improve their hearing experience, according to the company.
Denmark-based Widex launched the WIDEX EVOKE hearing aid in April. The hearing aid is reportedly the first to give users the ability to employ real-time machine learning that can solve the tricky hearing problems that users face in their daily lives.
“We launched WIDEX EVOKE with SoundSense technology to put users back in control of the most difficult hearing situations,” said Jens Brehm Nielsen, data science & machine learning architect at Widex. “And we can see that EVOKE users have taken the opportunity to do that and, in the process, are helping us understand more about them. That information will help us to make the EVOKE and future hearing aids even better.”
Hearing aids in Bucks
SoundSense Learn is an AI system, because AI is said to refer to systems that solve tasks humans are inherently good at—such as driving a car, doing the dishes, etc. SoundSense Learn expands into entirely new applications by helping end users adjust their hearing aids in the moment, reportedly something that no humans can replicate to the same degree of accuracy, according to Widex.
The SoundSense Learn smartphone app is connected to the EVOKE hearing aids and uses machine learning to guide users in optimizing the settings to their exact needs. The app gathers a variety of anonymous data such as how often they turn the volume up or down, which sound presets they use, and how many custom settings they create—including those made with SoundSense Learn.
Ear wax removal Amersham
Tagging of custom settings has proved to be one of the interesting pieces of data generated by EVOKE.
“We found that many people have created a setting and tagged it with, for instance, ‘work’ which suggests that it is something that our end users need and want,” said Nielsen. “And from SoundSense Learn we already have an idea of how they like the settings.”
Some hearing aids give users the ability to customize their sound experience by adjusting frequency bands to boost or cut bass, middle or high tones. Adjusting frequencies works well in many situations once the initial settings have been set by a skilled audiologist. However, some situations are so complex that hitting the right combination of adjustments can be difficult.
“Widex hearing aids are well known for the quality of their sound,” said Nielsen. “But SoundSense Learn has added an extra layer of quality sound on top of that by using a machine learning algorithm together with reinforcement learning—the two key ingredients in state-of-the art AI algorithm, that enables the algorithm to learn in the moment.
“The algorithm learns an optimal setting every time a user finds the sound to be a little below expectations in a given sound environment. It learns these settings by simply asking the user to compare two settings that are carefully picked by the algorithm. This allows it to learn an optimal setting in a new environment very fast.”
By collating and analyzing the anonymous data WIDEX EVOKE will continue to become even smarter as time passes.

Original story by the Hearing review
Chalfont hearing Blog:
How long should the hearing aid battery last after a full charge, and how does Bluetooth affect this
Q: How long should the battery last after a full charge? How much does Bluetooth activity affect this?
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?
The Chalfont Hearing Centre for ear wax removal in Bucks
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.
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.
Q: What would happen if my patient accidentally places their hearing aids in the charger while they have zinc air batteries in them?
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.
Ear wax removal Chalfont,Bucks
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.

Swedish University Researchers Develop New Test for Balance Disorders
Many individuals over age 65 suffer from dizziness and problems with balance; however, tests to identify the causes of such problems are often painful and can risk hearing damage. Now, researchers from Chalmers University of Technology have developed a new testing device using bone conduction technology that is said to offer “significant advantages” over current tests, the Sweden-based university announced.
A Vestibular Evoked Myogenic Potentials (VEMP) test uses loud sounds to evoke a muscle reflex contraction in the neck and eye muscles, triggered by the vestibular system—the system responsible for our balance. The Chalmers researchers have now used bone-conducted sounds to achieve what they say are better results.
“We have developed a new type of vibrating device that is placed behind the ear of the patient during the test,” said Bo Håkansson, a professor in the research group ‘Biomedical signals and systems’ at Chalmers.
The vibrating device is small and compact in size, and optimized to provide an adequate sound level for triggering the reflex at frequencies as low as 250 Hz. Previously, no vibrating device has been available that was directly adapted for this type of test of the balance system.
In bone-conduction transmission, sound waves are transformed into vibrations through the skull, stimulating the cochlea within the ear, in the same way as sound waves go through the ear canal, the eardrum, and the middle ear. Håkansson has over 40 years of experience in this field and has previously developed hearing aids using this technology.
The cause of dizziness can be difficult to diagnose for several reasons. In 50% of cases, dizziness is due to problems in the vestibular system. But today’s VEMP methods have major shortcomings, and can cause hearing loss and discomfort for patients.
For example, the VEMP test uses very high sound levels, and may, in fact, cause permanent hearing damage itself, according to the university’s press release. And, if the patient already suffers from certain types of hearing loss, it may be impossible to draw any conclusions from the test. The Chalmers researchers’ new method offers significant advantages.
“Thanks to this bone conduction technology, the sound levels which patients are exposed to can be minimized,” said postdoctoral researcher Karl-Johan Fredén Jansson, who made all the measurements in the project. “The previous test was like a machine gun going off next to the ear—with this method it will be much more comfortable. The new vibrating device provides a maximum sound level of 75 decibels. The test can be performed at 40 decibels lower than today’s method using air-conducted sounds through headphones. This eliminates any risk that the test itself could cause hearing damage.”
The benefits also include safer testing for children as well as patients with impaired hearing function due to chronic ear infections or congenital malformations in the ear canal and middle ear.
The vibrating device is compatible with standardized equipment for balance diagnostics in healthcare and the cost of the new technology is estimated to be lower than the corresponding equipment used today.
A pilot study has been conducted and recently published. The next step is to conduct a larger patient study in collaboration with Sahlgrenska University Hospital in Gothenburg, where 30 participants with normal hearing will also be included.
