摘要：The device has a filter bank system with a multi-layer analysis filter bank (AFB)

and a multi-stage synthesis filter bank (SFB) to separate an input signal of the hearingapparatus into multiple sub-band signals by a set of filter bank channels and/or to againmerge the sub-band signals. The filter bank system has an equalization filter (EQ) tocompensate differences of complex frequency responses between the filter bankchannels. The equalization filter compensates damping or amplification differences andgroup delay differences between the filter bank channels.
