What Is Hearing Aid?
The most common misconception about hearing aids is that they provide normal hearing to their users – this is NOT SO!
Unlike eye correction devices which can restore vision to normal, hearing aids amplify and shape incoming sounds to take advantage of the remaining healthy portions of the auditory system to maximise your hearing.
Although hearing aids have different designs, they all have the same basic components. Sound is picked up from the environment by a microphone which changes the sound from an acoustic signal to an electronic signal. This signal is then processed and amplified by the hearing aid. The hearing aid receiver then changes the electronic signal back into sound and directs it into the ear canal via an ear mould or the hearing aid body itself.
