How do hearing aids work? Are they just blasting what they hear directly into the ear potentially causing more damage?
In: Biology
There are different kinds of hearing aids. The specific type depends on the damage to the ear.
If you just “hear bad” specialized amplifiers can be used to alter the volume and frequency range to improve your hearing.
If some parts of the ear are damaged a cochlear implant can be used. This is basically a microphone with some electronics that is direct hooked up to the nerves in the inner ear and stimulates them to allow hearing.
