How long will a fully charged hearing aid last
How long should the hearing aid battery last after a full charge, and how does Bluetooth affect this?
The Henley Hearing Clinic is a premier independent hearing company based in Henley Buckinghamshire. We supply all manufacturers hearing aid batteries and conduct hearing tests. Microsuction ear wax removal is our speciality here and we also still use the traditional technique of water ear irrigation if you prefer. Hearing aid batteries can be bought over the counter or we can post them to you if this is easier.
This Weeks blog is about the hearing aid battery and how long these should last from a full charge.

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 behaviour 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?

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.

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.
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.”
Children with Hearing Loss May Experience Higher Rate of Bullying
New UT Dallas research indicates that children and adolescents with hearing loss experience higher rates of peer victimization, or bullying, than children with typical hearing, UT Dallas announced in a press release on its website.
In the study, approximately 50% of the adolescents with hearing loss said they were picked on in at least one way in the past year. Previous studies show about 28% of adolescents in the general population report being bullied.
“I thought more children and adolescents with hearing loss would report getting picked on, but I did not expect the rates to be twice as high as the general population,” said Dr Andrea Warner-Czyz, an assistant professor in the School of Behavioral and Brain Sciences and a researcher at the Callier Center for Communication Disorders.
The study, which appears in the journal Exceptional Children, showed the type of bullying experienced by youth and adolescents with hearing loss mimics patterns in children with other special needs, with significantly higher rates of social exclusion.
More than one-fourth of adolescents with hearing loss indicated they felt left out of social activities, compared to only 5% of the general population reporting exclusion. These findings parallel published reports of fewer invitations to social events, lower quantity and quality of friendships, and higher loneliness in children and adolescents with hearing loss.
Researchers conducted an online survey of 87 children and adolescents ages 7 to 18 who wear cochlear implants or hearing aids for hearing loss. If they indicated they were picked on at all, the survey automatically generated follow-up questions on how often it occurred and why they thought they were targeted.
Approximately 45% said they did not know why, 20% said it was because of their hearing loss or cochlear implant, and 20% said it was because of how they looked or how they acted.
Based on information provided by parents and from other studies, Warner-Czyz said the problems with peers might reflect communication difficulties related to auditory skills.
“Sometimes they miss puns or a play on words, or other cues that have to do with humor. Or when something is said very quietly or in a noisy location, the student with hearing loss might miss it. And that can make them feel like an outcast, or it can make them look like an outcast,” she said.
“Friendships are important to most young people, but I believe are especially important for children with hearing loss.”
said Warner-Czyz. Alternatively, she said peer problems might indicate a broader issue of not recognizing social cues from conversation or distinguishing true friendship from acquaintances.
Researchers have previously said having at least one good friend is a protective factor against bullying. Most children in this study cited several or lots of friends, but anecdotal reports from parents and clinicians questioned the veracity of these friendships.
“Friendships are important to most young people, but I believe they are especially important for children with hearing loss,” said Warner-Czyz. “Anything parents can do to facilitate social interaction and friendship and letting them learn how to be a friend and who is a friend is critical.”
She said future research will delve more deeply into the reasons behind differences in friendship quality and peer victimization in children and adolescents with hearing loss to guide evidence-based, targeted therapeutic intervention and potentially contribute to effective anti-bullying programs geared toward children with special needs. She said these factors might go beyond individual youth characteristics to include a microsystem of school and home settings.
The research is part of a larger study exploring the quality of life in children and adolescents with cochlear implants.

Want to know what A.I. Hell is like?
How about interacting with a machine that repeatedly professes stupefaction when you just know it should know what you’re talking about?
I was excited when I heard last fall that Alphabet’s (GOOGL) Google’s new wireless ear pieces would perform a kind of “real time” translation of languages, as it was billed.
The ear pieces, “Pixel Buds,” which arrived in the mail the other day, turn out to be rather limited and somewhat frustrating.
They are in a sense just a new way to be annoyed by the shortcomings of Google’s A.I., Google Assistant.
The devices were unveiled at Google’s “Made By Google” hardware press conference in early October, where it debuted its new Pixel 2 smartphone, which I’ve positively reviewed in this space, and its new “mini” version of the “Google Home” appliance.
The Buds retail for $159 and can be ordered from Google’s online store.
Getting the things to pair with the Pixel 2 Plus that I use was problematic at first, but eventually succeeded after a series of attempts. I’ve noticed some similar issues with other Bluetooth-based devices, so I soldiered on and got it to work.
The sound quality and the fit is fine. The device is very lightweight, and the tether that connects the two ear pieces — they are not completely wireless like Apple’s (AAPL) AirPods — snakes around the back of one’s neck and is not uncomfortable.
The adjustable loops on each ear piece made the buds fit in my ears comfortably and stay there while I moved around. So, good job, Google, on industrial design.
Translating was another story.
One has to first install Google Translate, an application from Google of which I’m generally a big fan. Google supports translation in the app of 40 languages initially.
You invoke the app by putting your finger to the touch-sensitive spot on the right ear piece and saying something like, “Help me to speak Greek.” When you lift your finger, it invokes the Google Assistant on the Pixel 2 phone, who tells you in the default female voice that she will launch the Translate app.
Several times, however, the assistant told me she had no idea how to help. Sometimes she understood the request the second time around. It seemed to be hit or miss whether my command was understood or was valid. On a number of other occasions, she told me she couldn’t yet help with a particular language, even though the language was among the 40 offered. It seemed like more common languages, such as French and Spanish, elicited little protest. But asking for, say, the Georgian language to be translated stumped her, even though Georgian is in the set of supported tongues.
This dialogue with the machine to get my basic wishes fulfilled fell very far below the Turing Test:
Me: “Help me to speak Greek.”
Google: “Sorry, I’m not sure how to help with that yet.”
Me: “Help me to translate Greek.”
Google: “Sure, opening Google Translate.”
Me: “Help me to speak Georgian.”
Google: “Sorry, I’m not sure how to help with that.”
Me: “Help me to speak Georgian.”
Google: “Sorry, I don’t understand.”
Me: “Help me to speak Georgian.”
Google: “Sorry, I can’t help with that yet, but I’m always learning.”
Me: “Help me to translate Georgian.”
Google: “Sorry, I don’t know how to help with that.”
In answer to Thomas Friedman of The New York Times, who writes of a new era of “continuous learning” for humans, I would like all humans to tell their future robot masters, “Sorry, I can’t help with that yet, but I’m always learning.”
When it does work, the process of translating is a little underwhelming. The app launches, and you touch the right ear piece’s touch-sensitive area, and speak your phrase in your native language. As you’re speaking, Google Translate is turning that into transcribed text on the screen, in the foreign script. When you are fully done speaking, the entire phrase is played back in the foreign language through the phone’s speaker for your interlocutor to hear. That person can then press an icon in the Translate app and speak to you in their native tongue, and their phrase is played for you, translated, through your ear piece.
Even this doesn’t always go smoothly. Sometimes, after asking for help with one language, the Google Assistant would launch the Translate app and the app would be stuck on the previously used language. At other times, it was just fine. In the worst instances, the application would tell me it was having audio issues when I would tap the ear piece to speak, requiring me to kill the app and start again.
This is all rather cumbersome.
I went and tried Translate on my iPhone 7 Plus, using Apple’s AirPods, and had pretty much an equivalent experience, with somewhat less frustration. All I had to do was to double-tap the AirPods and say, “Launch Google Translate,” and then continue from there as normal. It’s slightly more limited in that the iPhone’s speaker is not playing back the translation for my interlocutor; that plays through the AirPods. But on the flip side, it’s actually a little easier to use the app because one can maintain a kind of “open mic” by pressing the microphone icon. The app will then continuously listen for whichever language is spoken, translating back and forth between the two constantly, rather than having to tell it at each turn who’s speaking.
All in all, then, Pixel Buds are just a fancy interface to Google Translate, which doesn’t seem to me revolutionary, and is rather less than what I’d hoped for, and very kludgy. It’s a shame, because I like Google Translate, and I like the whole premise of this enterprise.
At any rate, back to school, Google, keep learning.
A recent study has found that it is possible for the brain to cancel out some sounds, and focus on others when directed to. This is a particularly important consideration in hearing aid wearers, who need to relearn to listen with an acquired hearing loss. Hearing aids only provide an aid to hearing, focused listening and hearing tactics are just as important in achieving improved hearing.
I am constantly trying to reinforce to my patients that listening is just as important as hearing and that while I control their hearing they control their listening. Many patients are overwhelmed by sound when they are first fitted with a hearing aids, resulting on them being distracted by noise rather than listening to speech. However, when the patient finishes their acclimatisation period and is wearing the hearing aid all of the time, they will begin to become selective again. However, this is not a passive activity for the hearing impaired it is a much more demanding activity, that will take time to improve. Continued dialogue with your Audiologist is important to make the best progress.
