Improved Audio Filtration using IIR Filter

Abstract

There are five senses in a human being, one of which is hearing. Sometimes, a person might have problems by birth or tragically they have to go through a trauma which causes them to lose their hearing capability. A lot of people are currently having hearing impairment, but only one portion of them use hearing aids. It can become difficult to hear voices with high pitch for a person at hearing impaired. One of the main issues for humans is the hearing aids system and its main cause is noise. Digital hearing allows users to get required frequency depending upon their requirements. The implementation for this is done by using the MATLAB tool. The noise can be reduced by increasing the frequency so that it can be heard properly. Through the use of digital signal processing, one can improve the old conventional system for hearing to tackle hearing loss for further generations.
