Hearing aid
From Wikipedia, the free encyclopedia
A hearing aid is an small electrical machine which fits in or behind a person's ear. The purpose of a hearing aid is to make sounds louder so the person can hear spoken words and other sounds.
The two most common types of modern hearing aids are behind the ear aids and in the ear aids.
Before hearing aids were invented, people used "ear trumpets" also called ear horn[1][2]
