Description




Digital Hearing Aids are the most advanced sound amplification devices that are designed to help people with hearing loss to hear. All hearing aids whether it is analog or digital have a microphone, an amplifier and a receiver as a basic constituent which is driven by a battery. However, analog hearing aids amplify all the incoming sound irrespective of whether it is speech or noise. Thus, the quality of sound amplified through analog hearing aids is compromised.  On the contrary the digital hearing aids after capturing the sound waves convert it to digital signals. This is just an exact replication of each of the sound. A computer chip then analyses the signal to determine whether the sound is a speech or noise.  Then the microprocessor makes several modifications and amplifies and processes the digital signal to makes it more clearer and noise free. Finally, the miniature loudspeaker converts this filtered digital signal back to sound waves which is delivered into the ear canal for the person to hear.
