A hearing aid is a small electronic device that you wear in or around your ear. It makes some sounds louder so that a person with hearing loss can listen, communicate and participate in conversations between other people that don’t necessarily know they are deaf.
How Does it Work?
Hearing aids usually consist of a microphone, amplifier, receiver and battery. The microphone is to convert acoustic sound into electricity, the amplifier is to enhance the strength of a signal, the receiver is to turn an amplified signal to acoustic sound and finally, not to forget, the battery to provide power. Hearing aid works by the microphone picking up an acoustic sound and converting the sound into an electrical or digital signal, based on the type of hearing aid. An amplifier boosts the signal received. For some advanced devices, there are usually additional advanced processing added into the mix. Finally, a receiver or most likely known as a speaker converts the signal back into acoustic sound and send it into the user’s ear, the brain will then receive the sound and perceive the sound retrieved by the ear as speech.
