Design of Programmable Hearing Aid based on Frequency Filters Bands

Auns Q. H. Al-Neami | Balsam S. Aziz


Abstract: Hearing disorders are the most prevalent disabling conditions reported all over the world that affect about 10 % of the population. It adversely affects physical, cognitive, behavioral, and social functions, as well as the general quality of live. The first electrical hearing instruments was introduced 100 years ago, but only about 20 % of those who could benefit from hearing aids wear them, moreover, surveys suggested that about only 50 % of hearing aid users are satisfied with their hearing instruments. This indicates hearing technology even today is a prominent research area. This research work involves the design of programmable hearing aid with frequency filters bands to allow the user to tune the amplitudes selectively to a persons particular pattern of hearing loss to be amplified by PGA (Programmable Gain Amplifier) more than the rest. These filters are tested with the standard test input signal and also implemented. The result showed that output of filters bands are in the same phase and flattest group and lesser matching errors.
