Today’s hearing aids are technological marvels, with features undreamt of just a few years ago. In order to truly appreciate the work your hearing aids do for you, you must first understand how the intricate parts collaborate to deliver exceptional sound quality at a volume you can hear.
How Hearing Aids Work
No matter the style of hearing aid, they all utilize the same basic parts to help you hear. Small microphones collect sounds from the environment, then a computer chip with an amplifier converts the incoming sound into digital code. The hearing aid is programmed to analyze and adjust sound based on your unique hearing loss, then the amplified signals are converted back into soundwaves and delivered to your ears through little speakers called receivers.
The Parts of a Hearing Aid
Below is a breakdown of the different parts of a hearing aid and details about what jobs they perform.
Microphones in hearing aids work the same way stage microphones do – they pick up sounds and transform them into electrical signals that the processor can understand. Hearing aid microphones are tiny, highly advanced and precise in order to pick up sound as clearly as possible so you can hear well.
Hearing aid processors are the part that vary most from model to model. They handle the bulk of the work by transforming the electronic sound signals to match the exact specifications of your hearing loss. Hearing aid processors are essentially tiny supercomputers with the sole purpose of creating sound. The quality of the processor determines the features of your hearing aid.
The cable is the small, hollow tube that connects the hearing aid to the earpiece. It contains the wiring of your hearing aid so sound can be transmitted to your ear.
Another word for a receiver is the hearing aid speaker. Once sound signals travel through the cable, the receiver transforms them back into recognizable sound and plays it into your ear canal.
The battery powers the hearing aid. Most hearing aids take disposable zinc-ion batteries, but rechargeable models take lithium-ion batteries.
The casing is the plastic shell that houses the electronics of the hearing aid.
