Classification of Complex Sounds
Abstract
The work accomplished during the period, 11/1/90 - 10/30/91, involves the use of COSS analysis to estimate weights in various profile analysis tasks. This technique is a method for investigating how spectral information is used by listeners to discriminate complex sounds. A profile type task is essentially an empirical method for investigating how spectral information from different auditory channels is used to discriminate complex sounds. In a typical profile task, the standard consists of n tones of equal intensity and the signal consists of an increment in the intensity of a single tone complex. Since overall level is varied randomly on each stimulus presentation (over a range of 20 dB or greater), absolute intensity is not a useful cue. The first set of experiments examined listeners abilities to discriminate a flat spectrum (eight tones of equal intensity) from a 'rippled' spectra (consisting of a pattern of intensity changes across the entire spectrum).
