Modeling Perception of Spectral Profile Changes
In this thesis, we explore how the human auditory system represents and detects changes in a spectral profile. First, using profile analysis methods, we measure listeners' sensitivities to changes in spectral peak shapes ...
Representation of Spectral Profiles in the Auditory System, II: Detection of Spectral Peak Shape Changes
Based on the ripple analysis model outlined in Part I of this paper, predictions are made for the detection of shape changes in spectral peak profiles. Peak shape is uniquely described in terms of two parameters: bandwidth ...
Representation of Spectral Profiles in the Auditory System Part II: A Ripple Analysis Model
Based on experimental results presented in [Vranic-Sowers and Shamma, 1993], and on further physiological and psychoacoustical evidence, it is argued that the auditory system analyzes a spectral profile along two largely ...
Representation of Spectral Profiles in the Auditory System, I: A Ripple Analysis Model
A model of profile analysis is proposed in which a spectral profile is assumed to be represented by a weighted sum of sinusoidally modulated spectra (ripples). The analysis is performed by a bank of bandpass filters, each ...
