How do hearing aids work? Are they just blasting what they hear directly into the ear potentially causing more damage?
In: Biology
Imagine there are strings of different length inside the ear that vibrate to a well defined frequency and transform the signal to a nerve impulse that the brain interprets as sound.
When those strings snap we stop hearing sounds in that frequency, a hearing aid just “translates” those missing frequencies into ones that the person in question can hear
