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.
