How hearing aids work
Modern hearing aids are small, but they are doing a lot of clever work behind the scenes. A hearing aid picks up sound, cleans it up and makes it clearer, then delivers it into your ear, all in a fraction of a second.
The four main parts.
Every hearing aid, whatever the brand, is built around four parts working together.
Picks up sound from around you and turns it into an electrical signal.
The brain of the hearing aid. Analyses the sound, reduces background noise, and shapes it to match your specific hearing loss.
Turns the processed signal back into sound and delivers it into your ear.
Powers everything, either rechargeable or a disposable battery, depending on your hearing aid.
From sound to hearing, in milliseconds.
This whole process repeats thousands of times a second, continuously adjusting to what is around you.
The microphone picks it up.
Cleaned up and shaped to you.
Sent into your ear as sound.
Clearer, and matched to your hearing.
What modern hearing aids can also do.
A simple amplifier makes everything louder, including background noise. A modern processor is smarter.
Modern hearing aids double as wireless earphones, with sound shaped to your hearing loss. Bluetooth hearing aids.
The newest models use AI chips to pull speech out of a noisy room rather than just turning the background down. See our brands.
Volume, programmes and fine-tuning from an app, and remote adjustments from us where appropriate.
Rechargeable models give a full day of hearing from an overnight charge, no fiddly batteries. Rechargeable hearing aids.
Set up for you.
Hearing aids cannot fully restore hearing to what it was, but they make sound clearer and easier to understand. Your audiologist programmes yours from your hearing test results, then fine-tunes it at your fitting and follow-up appointments, so it is matched to your hearing rather than a generic setting.
