Hearing aid is an electroacoustic device used to selectively amplify theaudio sounds with an aim to make speech more intelligible for a hearingimpaired person. Filter bank is one of the important parts of digital hearingaid where the sub band gains of each filter can be tuned to compensate anindividuals unique hearing loss pattern. As the human perception is based onthe logarithmic scale, nonuniform filter bank outperforms uniform filter bank.The main advantage of nonuniform filer bank is that it requires less number ofsub-band filters, hence resulted in low hardware complexity and cost. Mucheffort has been devoted to design these nonuniform filter banks for hearing aidapplications. This paper aimed to provide a review of previous researches basedon nonuniform finite impulse response (FIR) digital filter bank for hearing aidapplication using frequency response masking (FRM) technique. By reviewingfilter banks, we try to find the difference between fixed and variable bandfilter bank and to give an insight about which method is more suitable formatching most common types of hearing loss. Papers which involved methods ofdesign, theoretical computation and simulation results of filter bank have beenreviewed.
