Hearing aids utilize incredible technology that gives you the power to hear sounds that you haven’t heard in years. In order to truly appreciate all the hard work hearing aids do to improve your communication and quality of life, you should know how all the intricate parts work together to help you hear.
How a Hearing Aid Works
In short, hearing aids work in three parts. First, microphones pick up sounds and convert them into digital signals. The processor increases the strength of the digital signal to the level your hearing loss requires. Finally, the receiver produces the amplified sound into the ear.
The Parts of a Hearing Aid
Below is a more in-depth look at all the parts of a hearing aid.
The microphones are essentially miniature versions of what you would see used on a stage. Hearing aid microphones are extremely small and precise so they can pick up sounds as clearly as possible. They then transform the soundwaves into electrical signals that can be interpreted by the processor.
The processor varies most from model to model. It does the bulk of the work, transforming and amplifying signals to the exact specifications of your hearing loss based on the programming your audiologist sets up. Processors are essentially tiny supercomputers with the sole purpose of creating sound. Any state-of-the-art features your hearing aid boasts are thanks to the processor.
This is the small hollow tube that holds the wiring of your hearing aid. It connects the processor to the earmold and transmits sound so your ear can hear it.
Another name for a hearing aid receiver is a speaker. Once electrical signals travel down the cable, the receiver transforms them back into sound and plays it in your ears.
The battery, obviously, is responsible for powering your hearing aid. Most hearing aids take disposable zinc-ion batteries, but newer models that are rechargeable utilize lithium-ion batteries.
The casing is the shell that protects your hearing aids. It is made of plastic and comes in a variety of styles and colors to match your aesthetic preferences. Some are treated with water-repellent coating to protect the electronics from rain and sweat.
