Klappentext This book brings together recent research on the ability of human listeners to discern changes in the shape of complex acoustic spectra. It systematically discusses issues surrounding the discrimination of a change in acoustic intensity and the physiological mechanisms responsible for this process. The book also proposes two new theories which attempt to explain spectral shape discrimination on the basis of more elementary auditory processes. The research described here is helping scientists gain a better understanding of auditory skills such as those involved in listening to music and speech. Zusammenfassung This book reviews recent research on the ability of human listeners to discern changes in the shape of complex acoustic spectra--what is known as auditory profile analysis. It also discusses in a systematic way issues surrounding the discrimination of a change in acoustic intensity and the physiological mechanisms responsible for these discrimination processes. The author concludes with two new theories that provide a way of understanding more complex auditory skills, such as those involved in listening to music and speech. This book will be of interest to psychoacousticians, psychophysicists, physiological psychologists, and experimental psychologists.
