A quasi-auditory filter based on normal natural-observation filter was proposed by Iijima for acoustic analysis or speech recognition. This filter did not realize nonlinear signal processing. observed in human auditory filter. In this study, we propose nonlinear auditory model by expanding the first-order fundamental element of normal natural-observation filter to second-order and introducing Q, that depends on the level of the input signal. The nonlinearity and the bandwidth of proposed filter are in good agreement with that of the human auditory filter.
