Understanding Hearing Aids

Hearing aids have been around for decades. The first hearing devices were just conical devices that you held up to your ear so that a person could speak into them. This would funnel the sound directly into your ear. Now there are more impressive types of hearing aids, working with a higher degree of technology. So, in modern times, how do hearing aids work?

Hearing aids use small microphones to make a soft sound louder. They do this by using a small microphone. This device will receive the sound that comes in and convert it to an electrical or digital signal and send that data to a speaker where it is turned into sound once again. Settings for these microphones take into account the degree of a person's hearing loss and their usual environment.
