What is a Hearing Aid?
A hearing aid is a complex and intelligent communication device, which is designed to help you to distinguish sounds across every frequency and to participate fully in the world around you.
There are many different types of hearing aids, as there are many different types of hearing loss, but all work to amplify sounds within a particular hearing range, making sounds louder and clearer. No hearing aid can restore perfect hearing, but the way in which they work can help you to hear many different sounds more clearly and even to detect sounds you may not have heard for many years.
How Hearing Aids Works
A hearing aid has three basic parts: a microphone, an amplifier and a speaker.
1. Sound enters the hearing aid through a microphone.
A microphone, set within the small hearing aid that you wear in your ear, picks up sounds around you.
2. Sound is processed and amplified.
Sounds are then analysed via the processing chip in the hearing aid, and processed sounds are sent to the amplifier.
3. Sound is delivered to a receiver.
Amplified sounds are sent to the loudspeaker inside the hearing aid device, which then transmits sounds into the inner ear where they are transformed into electrical impulses.
The brain receives these electrical impulses and processes them to create audible sounds.
Hearing aids are designed to work with the specific hearing loss problems you are suffering, so they will vary in design and you will work with a hearing loss professional to find the best hearing aid for you.
