The Structure Of A Hearing Aid And How It Works

A hearing loss can have a profound impact on your life, your career, and your relationships. If you choose the correct one, a hearing aid can make a significant difference in your ability to communicate while enhancing your enjoyment of life. Knowing what goes into the design of hearing aids will help you choose the most appropriate device for your hearing needs. Regardless of the style of hearing aid you have, all hearing aids share three essential components:

  • The hearing aid microphone picks up sounds and sends them to the amplifier. New technology distinguishes between speech and background noise, making it easier to understand a conversation.
  • Converting sounds from the microphone into an electrical signal and then sending the message to the receiver is the function of the amplifier. Amplification power is dependent upon the severity of the user’s hearing loss.
  • Power source. Batteries power the hearing device. Batteries may be either rechargeable or disposable, depending on the model.

These three components are in all hearing aids. Depending on the design and the severity of your hearing loss, a few other parts might be residing inside your hearing aid.

Buttons And Switches

Hearing aids that are of the receiver-in-the-ear (RITE) type come equipped with a button or a switch. A hearing healthcare professional programs the button or switch to perform different functions such as alternating between settings or increasing and decreasing volume. Make a point of knowing the purpose of your switch.

Wire

A hearing aid wire is typically thin and coated in plastic. The wire extends from the body of the hearing aid to the speaker, which resides in the ear. The transmission of power and signals takes place in the wire. Hearing aid wires feature conductor materials, shielding, and jacketing manufactured for custom hearing solutions.

Receiver/Speaker

Delivering the sound to the ear is the responsibility of the receiver, which is also known as the speaker. When the speaker receives an electrical signal from the amplifier, it converts it to sound. The speaker is inside the ear dome or earmold, depending on the severity of hearing loss and lifestyle.

Domes

A dome is a small piece of silicone that attaches to hearing aid tubing and fits deep in the ear canal. Domes come in an array of shapes and sizes to accommodate the unique anatomy of a person’s ear canal. A hearing healthcare professional can help you pick the appropriate size for a proper fit.

Earmold

Earmolds are plastic or acrylic and fit inside your ear canal to form an acoustic seal for the electronic sound coming in. The fit and the shape of your earmold will depend on the model of hearing aid you are utilizing and the severity of your hearing loss. Because they provide the highest amount of amplification, earmolds are for those with severe to profound hearing loss.
Hearing loss is a severe health issue, so do not ignore it. If you suspect that you may have a hearing loss, schedule a hearing screening with a hearing healthcare professional. Swift acting will significantly enhance the quality of your life.

Over-The-Counter Hearing Aids; What Does This Mean for Audiology?

As technology and medical research continue to advance, more facets of your healthcare are becoming increasingly over the counter, whether that be medication, devices, or just medical advice. Treatment for hearing loss is no exception, with over the counter hearing aids becoming an imminent reality, invoking worry in many audiologists across the country. As hearing aids become more accessible over the counter, audiologists fear the impact on their profession and practice. This disruptive innovation is poised to achieve a new market foothold, becoming a more attractive option to new consumers who are looking for the most convenient and simple transition into hearing aids, taking business from traditional hearing aid manufacturers and audiologists who often bundle devices into their services. Though they seem convenient, the introduction of OTC hearing aids shows that despite intentions to increase accessibility and reduce costs, patients are not receiving the treatment they desperately need in exchange for ease.

Don’t Bypass Your Doctors Appointment Just Yet

According to the OTC Hearing Aid Act, the intention was to increase accessibility and affordability of devices, though OTC hearing aids have done little to achieve those goals. In fact, they hinder the ability of patients to get the information and proper assessments that they should have before finding the most effective hearing aid. OTC Hearing Aids utilize a business model designed to bypass diagnostic evaluations, hearing needs assessments, and audiologists all together in favor of self-identifying a device. Not only does this keep patients out of their doctor’s office, but also from receiving the medical advice they may need, ignoring the advocation by organizations such as the American Academy of Audiology for required medical evaluations for OTC hearing aids. Moreover, “receiving an OTC device is expected to be based on self-perceived mild to moderate hearing loss, not measured hearing capability that directly aligns with the definition provided by ASHA.”
 
As hearing loss can differ greatly from patient to patient, it’s critical that patients do not bypass professional medical advice. Herein lies the fear of audiologists, as numerous unofficial polls conducted via social media and trade publications have documented the anxiety had by medical professionals as OTC devices are positioned to impact not only their practice but their profession as a whole.

Changing Public Perception

To combat this imminent and disruptive technology, Audiologists must aim to change public perception about the importance of their profession and medical advice regarding hearing loss. ”The efforts of the profession should be focused not on a device, but rather on educating the public such that they recognize audiologists’ value and demand access to it.” says Dr. Sarah Sydlowski, Audiology Director of the Otolaryngology department at Cleveland Clinic, ”Take every opportunity to reinforce the value audiologists provide. Emphasize the importance of a hearing evaluation before deciding to use any hearing device. Help the public understand that an inappropriate hearing device can be as detrimental as no hearing device.” With proper advocation, audiologists can continue to give the critical information required for patients with hearing loss, ensuring that patients do not give up their doctors for convenience.

This AI-Powered Hearing Aid Technology Is Changing How You Hear In Crowds

hearing in a noisy environment

Any sufficiently advanced technology is equivalent to magic. – Arthur C. Clarke (Author)
Our brains are the ultimate computer. They are always working and processing, anticipating and solving problems, running systems in the background while operating on the fly as we move through our lives. When it comes to hearing, the brain is just as crucial as the various parts of the ear.
What the brain can do, with the help of the ear, is to pick one voice out of a crowd and tune in to listen. So, what happens when hearing loss limits this advanced ability? Technology takes over.
The problem
While you may not often think about it, the way we can focus in on and listen to one voice in a larger, noisier crowd is pretty remarkable. Our brain quickly and seamlessly filters out others so we can hear the one. With hearing loss, this isn’t always possible. In fact, the difficulty so many with hearing loss face hearing in crowds or noisy settings is a problem so many hearing healthcare professionals and researchers have been trying to solve for years. With the newest technology, this problem could become a thing of the past.
AI Advancements
While hearing aids have steadily become more powerful with numerous advanced features over the years, isolating voices in crowds has still proved an elusive problem to solve. That’s why recent research of an exciting new piece of hearing aid technology has those in the world of hearing health cautiously optimistic.
Still, in the early stages of development, the new AI-powered hearing aid is powered by the brain. By monitoring brain waves, the device can automatically boost the voice the wearer would like to hear.
“By creating a device that harnesses the power of the brain itself, we hope our work will lead to technological improvements that enable the hundreds of millions of hearing-impaired people worldwide to communicate just as easily as their friends and family do,” said Nima Mesgarani, PhD, a principal investigator at Columbia’s Mortimer B. Zuckerman Mind Brain Behavior Institute and the paper’s senior author.
Using a speech-separation algorithm, the hearing aid can identify the voice on which the user wants to tune in. While previous versions were limited to just those voices that it recognized, this latest version, tested on volunteers epilepsy patients, can focus in on any voice in a crowd based on the brain waves and refined algorithm.
Hearing aids and hearing loss
Advances like this in hearing aid technology can mean more natural hearing for the millions of people diagnosed with hearing loss. This, in turn, could prevent millions more cases of associated conditions including depression, anxiety, social isolation and even cognitive decline. The possibilities are endless.
If you believe you or someone you care about have hearing loss, don’t wait for advanced hearing aid technology like this to take action. Contact our office to schedule an evaluation today. It’s vital that hearing loss is treated early to preserve your quality of life.
