| Abstract: | In the research of spatial hearing and realization of virtual auditory space, it is important to accurately model the acoustical characteristics of HRTFs (Head-related Transfer Functions) or HRIRs (Head-related Impulse Responses). In our study, for the sake of modeling HRIRs more truthfully, aiming at HRTFs’ characteristics in time domain, we managed to carry through adaptive non-linear approximation in the field of wavelet transformation and introduced a new spatial hearing approximation model based on translation-invariant a’ trous algorithm and reconstruction from modulus maxima. And the simulation results show that, this is a more effective HRIRs’ model, averagely 7.7dB better than the traditional PCA (Principal Component Analysis) approximation based on relative MSE criterion. | ||
