Opis

This book focuses on opera house acoustics based on subjective preference theory; it targets researchers in acoustics and vision who are working in physics, psychology and brain physiology. This book helps readers to understand any subjective attributes in relation to objective parameters based on the powerful and workable model of the auditory system.It is reconfirmed here that the well-known Helmholtz theory, which was based on a peripheral model of the auditory system, may not well describe pitch, timbre and duration as well as the spatial sensations described in this book, nor overall responses such as subjective preference of sound fields and the annoyance of environmental noise.

Recenzje

"This book's focus is on opera house acoustics based on subjective preference theory. ... The various mathematical concepts are clearly and succinctly summarized in combination with drawings and diagrams. This combination of mathematical concepts illustrated by visuals creates a content that can be understood by designers and performers that do not easily use mathematics, as well as engineers and mathematicians." (Bonnie Schnitta, Noise Control Engineering Journal, Vol. 65 (1), January-February, 2017)
