Benefits of hearing aids
The Chalfont hearing Centre is a premier independent hearing company based in Little Chalfont Bucks. Leon Cox, the lead audiologist is here to help you diagnose your hearing symptoms along with other hearing issues such as possible ear wax blocking the ear canal. Ear wax can be easily dealt with by Micro-suction that gently hoovers out the ear wax cleanly and quickly.
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.

Phonak Launches Marvel with Universal Binaural Streaming and New Level of Sound Quality
New levels of binaural sound quality and universality. One key feature that immediately jumps out in Audéo M is its sound quality. For real audiophiles and others accustomed to hi-fi systems, the sound quality in today’s hearing aids is very good, but can still prompt them to ask why the devices can’t sound like stereo headphones. Of course, the problem—which has been around even before made-for-iPhone (MFi) systems became available—stems primarily from the venting of the aid for real-life environmental speech and sounds. This provides the important natural sound benefits associated with open-fit aids, but has required a trade-off in streamed sound quality. With the Audéo M, Phonak has reinserted a clear richer sound into streamed music, TV, or other devices via hearing aids—and demonstrated fairly dramatic differences in a paired comparison test. The system features AutoSense OS 3.0 which reportedly classifies streamed media for optimized listening.
“We have the first classifier that also operates on the streamed signal,” said Christine Jones, AuD, Phonak US vice-president of Audiology and director of the Phonak Audiology Research Center (PARC) in Warrenville during a presentation at the media event. “Some of the early work we did highlighted that there was an opportunity with streaming—as with the unique listening environments that can also be encountered by patients—where someone’s preferences may be very different than when listening to streamed speech, or dialog in media, movies, etc. Listening goals can be different, and sound quality preferences can be different. So, now we are not only classifying the environmental sounds, but we can also classify those streamed sounds to deliver the best possible experience under all listening conditions.”
Although the advanced design of the previous Audéo B-Direct model is award-winning, it does not feature binaural streaming. With the new Audéo M, wearers can now binaurally stream audio content, including smartphone calls, music, eBooks, and more, to both ears from any Bluetooth device.
Phonak points out that iPhones account for only 13% of smartphone use worldwide compared to 86% for the Android OS, and wearers’ choices have been limited primarily to hearing aids that utilize the MFi protocol. Additionally, even with IOS-compatible devices, some forms of MFi hearing aid streaming (eg, streaming from MacBooks and iMacs) were unavailable until now. SWORD 3.0 is capable of running Bluetooth Classic, Bluetooth LE, AirStream Technology (for TV), and Binaural VoiceStream Technology for high-speed data transmission between the two hearing aids in a binaural fitting. The new system even works with Siri and LiveListen. (Phonak’s proprietary Roger 2.4 GHz signal will also have direct streaming capabilities to the hearing aid next fall.)
“This means we now have universal binaural wireless connectivity,” said Dr Jones. “In order to have the best access to speech on the phone, it’s best to hear well with both ears. And, beyond that, we are the only product that now connects to not just Apple and Android, but any Bluetooth device. This opens up a new world of connectivity for people because of its universal nature…What this means is, that in those cases where something is not accessible through the Apple iPhone or device, it should be accessible through the hearing aid.”
Jones explained that Phonak has also created a sophisticated system called “Environmental Balance” that controls how users hear the streaming in addition to how they hear the surrounding environment, both of which can still be adjusted via the basic volume control. All of this has the potential to open up even more of the popular streaming applications.
Better processing and noise reduction, reducing cognitive load.Additionally, the enhanced SWORD OS incorporates Binaural VoiceStream Technology™ into Marvel hearing aids, a technology most recently employedin Advanced Bionics’ Naida CI sound processor. This four-microphone technology is reportedly capable of improving speech understanding by up to 60% in noisy places like restaurants, while simultaneously reducing the amount of effort by 19% required to listen and understand.1,2
“Audiology is at the heart of everything we do at Phonak,” said Sonova Group VP Martin Grieder in a press statement. “That’s why Marvel is such a game-changer for our industry. Marvel technology empowers people and provides a true ‘love at first sound’ experience. We believe the sound quality is second to none, and it begins the moment the person puts the hearing aids on.”
Lithium-ion rechargeable technology for “a full day of streaming.” While no reliable statistics exist on the market penetration of rechargeable hearing aids, most experts estimate that about 17-20% of all hearing aids now feature rechargeability. Phonak has been a pioneer in rechargeable hearing aid technology, creating in 2016 the first lithium-ion hearing aids—a technology that appears to be gaining ground with hearing aid manufacturers.
According to Phonak, Marvel hearing aid wearers can enjoy a full day of hearing aid use—including streaming— on a single charge. The Audéo M rechargeable hearing aid also offers new features, automatically turning on or off when taken out or being placed into the charger. The system includes new LED lights and a new mini charger.
Remote fine-tuning and live voice-to-text transcription apps. With Marvel hearing aids comes the introduction of a suite of convenient smart apps. The myPhonak app allows wearers to have their hearing aids adjusted in real-time, in any situation, anywhere via videocall by the hearing care professional. It also gives consumers the ability to rate their hearing aid satisfaction in various environments and directly send this feedback to their hearing care professional.
The myCall-to-Text app reportedly provides live transcription of phone calls from the other party in more than 80 languages. This provides an extremely useful option for hearing aid users in noisy environments, or for people who prefer additional visual captions when using the phone.
New marketing campaign and rollout. A suite of marketing materials has been developed to promote the Marvel launch. Phonak US Vice-president of Marketing Barb VanSomeren explained that the marketing surrounding Marvel emphasizes its multifunctionality, providing consumers with access to the world of sound that we all want via enhanced sound quality, a constellation of devices and streaming options, and phone calls. The new marketing assets highlight Phonak technology, audiology leadership, and Marvel’s diverse capabilities, and includes a video series that features two women exploring all the different ways Marvel can be used in a contemporary format (eg, the women’s dialog resembles the TV show Grace and Frankie) .
The rechargeable Audéo M-R will be available in November along with the zinc air Audéo M-312, and Phonak will add the Audéo M-312T and Audéo M-13T in February 2019. A rechargeable version of Marvel with T-Coil (Audéo M-RT) and RogerDirect functionality will be available as a firmware upgrade in Fall 2019.

Chalfont hearing news:
Though public transportation is thought to be better for the environment in that it reduces greenhouse gas emissions, saves energy, and improves air quality, according to the Federal Transit Administration, there may be a negative effect on your personal health.
According to a recent Canadian study, commuters traveling during peak hours were exposed to maximum noise levels. A summary of the study’s results, published on the Hear-it AISBL—a nonprofit organization that provides information on hearing loss—website, show the results of the study, which was published in the Journal of Otolaryngology—Head & Neck Surgery. In this article, we’ll share the highlights, edited and adapted from the Hear-it website.
Researchers looked at two different commuting situations among Toronto residents: people waiting for a streetcar/bus as compared to people walking/biking to a subway. Bikers were exposed to louder noise than those walking or driving a vehicle. Noise levels were higher for those waiting on a subway platform as compared to those in the subway car. And, finally, research showed that those waiting at bus stops were exposed to the loudest noise of all.
Though commuters often only experienced short and intense bursts of impulse noise exceeding the 114 dBA limit recommended by the EPA, researchers concluded this can be just as harmful as prolonged noise exposure. Up to 20% of the peak mean noise measurementsexceeded 114 dBA, and up to 85% of measurements at bus stops were higher than 120 dBA, according to the study. Researchers were concerned that prolonged exposure could lead to noise-induced hearing loss.

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.
Latest research indicates that common ear infection drugs trigger bacteria to build defences, meaning that for some children and adults what does kill the bacteria, instead makes them stronger. (more…)
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.
The link below is to a video which explains the details of the hearing study in more depth
When patients begin to tackle their hearing loss, I have found that many feel like they are the only person experiencing what they are going through. Most patients display very similar issues and concerns. However, there is not always positive and constructive advice available. That is why Chalfont Hearing are supporting the local Hard of Hearing Club. This organisation provides the opportunity to meet other people who are similarly affected and discuss new experiences. We promote a holistic and engaging approach to rehabilitation of hearing loss.
This Club has been in existence for over 30 years and is the only one of its kind now remaining in the Bucks, Berks, Herts and Oxon area. It is a friendly and caring club, supporting its members, who have widely differing degrees of hearing loss. During its yearly programme there are at least two evenings devoted to ” Hearing Matters,” while other speakers inform and entertain on a variety of topics. They welcome members from a wide area and try to publicise the benefits the Club has to offer by attending Open Days such as the event held by Chalfont Hearing Centre, whose welcome at the event was much appreciated.
This ” Cindarella of Disabilities” is at last beginning to reach a greater understanding by the general public, and support and advice is becoming more easily available. The Club aims to provide an informal and happy environment for older men and women for whom isolation and lack of communication would become a real problem.
They are always pleased to welcome enquiries and visitors.CONTACT: Kate Weber, 7 Webb Close, Chesham, Bucks, HP5 2JQ ( 01494-773359; Text Messages: 07757 639066)
The weather blessed a busy September day in Chalfont St Giles, Amersham. The show was busy and our hearing roadshow stall was extremely busy. It was nice to speak to the local community and help inform them of the options with regards to accessing hearing healthcare. It’s shocking how many people don’t know where to get a hearing test or the importance regular hearing tests for the over 55’s.
For all those that attended on the day thank you for your support and interest!
