Abstract
This paper proposes an efficient bank of filters derived from variable bandwidth filter structure, for audiogram matching in a digital hearing aid. The variable bandwidth filter is designed using Farrow structure, for lower hardware complexity. The magnitude and band edge frequencies of the filters are independently adjustable which allows this arrangement to successfully fit a given audiogram with as minimum number of bands as possible.
