Abstract
A computationally efficient 16-band non-uniformly spaced digital FIR filter bank is proposed for hearing aid applications. The filter bank is constructed by three prototype filters based on the principle of frequency-response masking technique. It requires only 34 multiplications in the implementation of a 16-band filter bank with stopband attenuation of -60dB. The simulation results show that the proposed filter bank achieves good matching between audiograms and filter magnitude responses. The filter delay is significantly reduced compared to that of the 8-band non-uniform filter bank [8].
