 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? —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.

Much like a car's mileage range depends on its gas tank and the owner's driving habits, the battery life of a hearing aid depends on the capacity of the battery, and the listening enviroments and use of the various hearing aid functions.

Hearing aid batteries last how long?

Much like how a car’s mileage range depends on its gas tank, the driving conditions, and the owner’s driving habits, a hearing aid’s battery life depends on the capacity of the battery, the wearer’s listening environments, and use of the various hearing aid functions, including audio streaming.

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?

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.

ZPower Rechargeable Hearing SystemQ: 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.

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

Original story by The Hearing Review

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.

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.

More about the research

The scientific article “VEMP using a new low-frequency bone conduction transducer” has recently been published by Dove Medical Press, in the journal Medical Devices: Evidence and Research.

Chalmers’ partners in the study are the Sahlgrenska Academy at the University of Gothenburg, and the Danish audio companies Ortofon andInteracoustics. Grants for this project are received from Vinnova (Swedish Innovations Agency) and Hörselskadades Riksförbund (Hearing Impairment Federation).

Widex Announces New Insights into EVOKE Hearing Aid’s AI Function

Original story by the Hearing review

Ear wax removal Torbay, Torquay & Teignmouth

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.”

Living in Torbay

Living in Torbay and you are hard of hearing, but need friendly hearing advice? We can do a very quick hearing test and check  that you are clear of ear wax before consulting on any solutions.

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.

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.”
