Abstract

To reduce the surrounding noise in the hearing aids by using active noise control system. Background noise is particularly damaging the speech intelligibility for people with hearing loss. Background noise reduces the clarity in the speech. So we are able to understand speech in moderately in noise environment even at the sufficient signal to convey the information. There is less redundancy in the speech signal for a person with hearing loss. Since part of the speech is either audible not or distorted because of hearing loss. So people with hearing loss have much greater difficulty than normally hearing people in understanding speech in noise. This problem will be avoided by combination of active noise control and noise reduction algorithm.
