Karjalainen, Matti. A Binaural Auditory Model for Sound Quality Measurements and Spatial Hearing Studies ICASSP-96, Atlanta Abstract: This paper addresses the modeling of binaural auditory perception. There are numerous potential applications where computational modeling may yield practical results or improved insight into the problem domain. The focus here has been to develop models for spatial sound quality measurements and general studies of spatial hearing. The novelties of the paper are related to auditory filterbank designs, temporal processing schemes, and binaural processing s trategies. Several auditory filterbanks are experimented, including new designs using warped filters. The temporal processors of the model are based on nonlinear feedback where fast neural firing-rate responses and slow loudness responses are obtained as complementary outputs. A binaural processor combines the interaural cross-correlations and level ratios of left and right channels using neural networks, yielding directional estimates of the source of the sound.
