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.

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.
