Study of Audiogram for Speech Processing in Hearing Aid System
Published in Institute of Electrical and Electronics Engineers Inc.
The human ear is a very delicate, sensitive and complex organ. Woefully, any damage to the ear, whether through any disease, injuries, revelation to extreme loud noise, some medicines or may be the effects of old aging, can cause the ear to damage or glitch. Approximately 467 million people in the whole world are suffering from hearing loss and 34 million of these are kids, but only few people out of this statistic use the hearing aid. The drawbacks and disgrace associated with wearing a hearing aid due to large size, patient's dissatisfaction with the performance of hearing aid, the cost and the life of battery. Considering present hearing impairment all over the India as well as world, it is very much necessary to explore new technology and idea to satisfy the need of deaf people in the society.This paper explains the concept of various audiograms for speech processing in hearing aid, various algorithm for impedance matching, various techniques for filter bank signal processing algorithm using Fast Fourier Transform and Wavelet transform and echo cancellation techniques [5] that have low complexity in terms of hardware, a lesser power dissipation, consumes lesser area, so that the total power dissipation consumption and area and size of the hearing aid can be minimized and will also enhance speech Intelligibility by using suitable filter. © 2019 IEEE.
