Topic : Dynamic Frequency Filtering based on Analysis of Hearing Impairment

Authors:Padmaja Kuruba || Tilak Kumar L

Abstract:Worldwide more than 10% of the people are suffering from Hearing impairment. The statistical report shows more than 20 crores of people are subjected to various levels of hearing problems based on various reasons depending on the surrounding environment. Hearing impairment is seen in all age groups from infants to adults. In this paper, we propose a digital hearing system which mimics the biological ear. The system is designed to produce required sound based on the patient impairment level, using digital signal processing techniques. This involves noise reduction, the frequency selected filtering & amplification and compression such that bouncing of the frequencies is avoided. The proposed work is simulated using MATLAB where the following parameters are tested namely 1) reduction of white Gaussian Noise 2) increase in the gain of specific frequencies 3) dynamic shaping of the signal amplitude to reduce bouncing of the signal..

Keywords: Hearing Impairment, Gaussian Noise, Filtering.
