If you are serious about keeping your mental health in check please make an appointment and let us help with any hearing issues you may have. it could be a simple as clearing your ear wax!

 

Bellow is a snippet of information from the latest British Irish hearing instrument manufacturers association meeting discussing cognitive decline.

Panel on Issues Facing Hearing Industry

BIHIMA, British and Irish Hearing Instrument Manufacturers Association
Over half (55%) of audiologists do not believe their patients are aware of the link between hearing loss and cognitive decline, according to the results of an audiologist research panel, conducted by the British Irish Hearing Instrument Manufacturers Association (BIHIMA), the Association announced.
BIHIMA questioned approximately 70 audiologists across the private sector and NHS, in April 2019, on issues facing the hearing industry today. Many audiologists on the panel highlighted the increasing need for their consultations to include an education piece on the growing body of research connecting hearing loss and cognitive decline.
BIHIMA Chairman, Paul Surridge, believes the industry has a duty to empower audiologists to deliver this crucial education work: “It is essential that we work together as an industry to educate patients about the link between hearing loss and cognitive decline. If, as our research suggests, this education work tends to lie with audiologists, then we must do all we can to help and support them, as we did in our recent Dementia Round Table at the RCGP.”
The panel was also questioned on the technology trends of the future. They highlighted the following key trends for hearing tech (in order of priority): 1) Signal processing, 2) Smart technology and mobile apps, 3) Remote tuning of hearing devices, 4) Biometric monitoring of brain/heart function, and 5) Rechargeable hearing aids. Other trends mentioned include Artificial intelligence, OTC hearing aids, wireless accessories, and wearables.
The audiologists concluded that the biggest innovation challenges the industry faces in the future are: complexity leading to consumer inability to utilize the technology, battery life, lack of real-world testing, small scale, design appeal, speech recognition in noise, and connectivity.
The top reasons patients seek hearing aids from an audiologist were listed as: Not able to hear people talk, peer or family pressure, social isolation, work issues, unable to hear on the telephone, tinnitus, and hearing speech in noise.
Finally, the panel was asked how frequently they think people should get their hearing checked. Audiologists working in the private sector reported annual visits, whereas NHS audiologists said that, on average, their patients come for a hearing test every 3 years.
Surridge concludes: “It is a concern that private and NHS opinions on the frequency of hearing checks differ, as BIHIMA’s view is that hearing tests for the over 55s should take place once a year and be considered part of peoples’ regular health check routine, like dental and eye care. We intend to seek further feedback on this issue as we believe there needs to be an industry standard that all agree to, so we invite you to share your thoughts with us via our Facebookand Twitter channels.”
BIHIMA brought together this panel of experts in audiology to consult on industry matters. Its aim is to ensure the technology developed by its members is influenced by the knowledge and expertise of audiologists, and so that BIHIMA’s contribution to public discussions around hearing loss remains well informed.
About the Research:
  • The BIHIMA Audiologist Research Panel is made up of NHS and private audiologists, actively practicing in the UK
  • 71 respondents made up the May 19 panel—62% private v 38% NHS
  • Respondents were asked 10 questions via an anonymous online survey
  • Date: February-April 2019

If you need hearing aids

Hearing aids won’t make your hearing perfect, but they make sounds louder and clearer, reducing the impact hearing loss has on your life.

Hearing aids can:

  • help you hear everyday sounds such as the doorbell and phone
  • improve your ability to hear speech
  • make you feel more confident when talking to people and make it easier for you to follow conversations in different environments
  • help you to enjoy listening to music and the TV, at a volume that’s comfortable for those around you

But hearing aids only help if you still have some hearing left, so don’t put off getting help if your hearing is getting worse.

To book your appointment at the Chalfont hearing centre please call reception and speak with our receptionist.

New Hear-it Report Documents Extraordinary Costs of Hearing Loss in EU

 

hear-it_tw_400x400

In the EU, untreated hearing loss costs 185 billion Euro–each year. –hear-it.org

A new scientific report, “Hearing Loss – Numbers and Costs”, concludes that untreated, disabling hearing loss costs 185 billion Euros (US$211 billion) in the EU each year. This represents 8,200 Euros  (US$9335) each year per person with an untreated disabling hearing loss.

The detailed findings and conclusions in the report will be presented at a lunch debate at the European Parliament in Brussels, Belgium, on the March 6 in connection with the WHO World Hearing Day on the 3rd of March.

The report was carried out for the non-profit organization, hear-it AISBL, by Professor Emerita Bridget Shield with the assistance of Professor Mark Atherton at Brunel University in London. In 2006, Professor Bridget Shield compiled the first report for hear-it AISBL, “Evaluation of the Social and Economic Costs of hearing Impairment.”

How they arrived at the 185 billion Euro figure. According to the report, lower quality of life due to disabling hearing loss costs the EU 130 billion Euros (US$148 billion) each year. Lost productivity in society due to a higher unemployment among people with a disabling hearing loss costs 55 billion Euros ($63 billion) each year in the EU. In total, this is 185 billion Euros. The cost does not cover extra health care costs caused by hearing loss. A disabling hearing loss is defined by the Global Burden of Disease research group (GBD) as a hearing loss of 35 dB or greater.

In Europe as a whole—including non-EU countries—untreated, disabling hearing loss costs 216 billion Euros (US$246 billion) each year, says the researchers.

Chalfont hearing centre for all 2019 hearing aids

The report documents that the use of hearing aids and other hearing solutions improves health and increases quality of life. It also documents that people with an untreated, disabling hearing loss are at greater risk of social isolation, depression, cognitive decline and dementia, while people who treat their hearing loss do not experience a higher risk than people without hearing loss.

There are 34.4 million people with a disabling hearing loss (35 dB or greater) in the EU. More than 22.6 million are not treated for their disabling hearing loss as only around 1 in 3 in Europe with a disabling hearing loss use hearing aids or other hearing solutions. This is more than the combined population of Austria, Finland, Ireland, and Lithuania. With a steadily aging population who live longer and with an earlier onset of hearing loss due to increased noise exposure, this growth will increase even further in the years to come, warns Hear-it.

Chalfont hearing centre for all 2019 hearing aids

A meta study. The report, “Hearing Loss–Numbers and Costs”, is a meta study which has analyzed and compared hundreds of scientific studies and papers in the last two decades about the prevalence and the consequences of hearing loss and the use and benefits of hearing aids, according to the organization.

Kim Ruberg

“The scientific report clearly demonstrates that untreated hearing loss is a major health issue and that untreated hearing loss has a huge economic and social impact on our society,” said Secretary General Kim Ruberg, hear-it AISBL, on the organization’s website. “It also documents that checking your hearing and treating hearing loss pays, both for the individual and for society.”

Check your hearing. World Hearing Day is held by the WHO on the 3rd of March each year to raise awareness of how to prevent deafness and hearing loss and promote ear and hearing care across the world. The theme for World Hearing Day 2019 is “Check your hearing”.

Chalfont hearing centre for all 2019 hearing aids

“If you think you might have a hearing loss, my best advice is to get your hearing checked,” says Ruberg. “You can start by checking your hearing using the WHO “Check your hearing” app, or test your hearing online at www.hear-it.org. But if you suspect that you have hearing problems my best advice is that you get a real hearing test carried out by a hearing professional,” says Ruberg.

BIHIMA_LOGO_RGB_150dpi

The British and Irish Hearing Instrument Manufacturers Association (BIHIMA) announced its release of the Q3 results of its members, providing a picture of current trends and developments within the UK and Irish hearing care markets.

According to BIHIMA’s announcement, the “most significant” development is the continued growth in the number of units distributed through the private market in the UK: the number of unit sales increased by 2,756 units (3.5%) from the previous year and by 2,638 (3.3%) from Q2 2018. YTD (year-to-date) unit sales were also up 3.8% from 2017.

Meanwhile, the BIHIMA reports that the NHS side of the market slowed down in the same period: unit sales were flat compared to Q3 2017 and decreased by 7445 (2.2%) from Q2 2018.  YTD units were down 1.6% from 2017.

BIHIMA also tracks the trends in the types of technology being selected by patients in the private sector. In the private sector, the RITE/RIC (receiver-in-the-ear technology) continues to grow in popularity and now represents 69.4% of all sales, up 1.7% from Q3 2017.

“We are seeing solid growth in the private hearing care sector which is in line with expectations based on our aging population and also points to evolving public awareness of the hearing technology produced by our manufacturers which can have transformative results,” said the BIHIMA chairman, Paul Surridge.

In its role as the voice for the hearing technology industry, BIHIMA regularly monitors the market and releases the results of its members every quarter.

Widex Announces TV PLAY and RedDot Award Honor

Original story by the Hearing review

Widex TV PLAY.

Widex A/S, Lynge, Denmark, the privately-owned Danish hearing aid company, has announced the launch of WIDEX TV PLAY, a high-end TV accessory and streaming solution for WIDEX EVOKE hearing aids. The sleek and versatile TV PLAY received the Red Dot Design Concept Award last Friday, September 28, for its pleasing design.

Bucks hearing aids

WidexWidex has also been honored as a leader in innovation in the RedDot Design Ranking for Design Concepts. The company placed number 4 out of 15 companies in the Americas and Europe region in recognition of its pursuit of design excellence over the past 5 years, reports the company.

Shipments of TV PLAY will start in November.

A valuable accessory for hearing aid users. A 2017 Nielsen survey1 reported that the US 65+ population consumes a daily average of 6 hours and 57 minutes of TV. Despite the growing number of mobile and web-based streaming services, watching TV is more popular than ever. But for some, it’s a struggle to hear the TV. Hearing aid users can find it hard to hear the TV over the other sounds in the room. In fact, some studies suggest that 78% of hearing aid users have trouble understanding things on the TV.

Hearing aids Chalfont Bucks

Designed for ease of use. According to Widex, TV PLAY lets hearing aid users enjoy great TV sound effortlessly through their hearing aids by providing direct streaming to both ears. TV PLAY is designed for fast and easy to set up, intuitive to control, and delivers outstanding and stable sound.

TV PLAY drops the “boxy” look of many TV streamers and instead has a futuristic design that blends in with modern homes. And if you prefer to have TV PLAY out of sight, the slim and discrete design fits behind flat screen TVs with no trouble, according to the company.

“At Widex we work to ensure that hearing aid users get the most of all aspects of life,” said Widex President and CEO Jørgen Jensen in a press statement. “We know that TV is an important part of staying in touch with the world around them through news and entertainment programs. TV PLAY gives them a better and more stable experience that also looks great in their living rooms.”

Maximum streaming stability. With Widex’s patent-pending dual-antenna technology, TV PLAY is said to offer maximum streaming stability. An easy-to-use app lets users balance the volume of the TV sound with ambient sounds and conversations—or choose just to hear the sound from the TV.

Hearing aid batteries last how long?

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 Chalfont hearing centre is a premier independent hearing company based in Chalfont 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.

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.

 

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?

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.
