Models of signal processing in human hearing

The paper presents a theoretical system model of the monaural signal processing in the human auditory system. Moreover, it deals with the application of this hearing model to the calculation of just-noticeable amplitude differences and variations, as well as elementary psychoacoustic parameters and a deconvolution algorithm for the detection of dominant spectral components based on the excitation pattern of the basilar membrane. The use of the hearing model for sound quality tasks allows evaluating the temporal and spectral patterns of a sound (“Relative Approach” analysis) where absolute level or loudness is often without significance.
