Description

This self-contained reference brings together the signal processing and subjective and physical aspects of modern room acoustics. The authors introduce the basic technologies of sound field control at a level which assumes basic knowledge of the Fourier transform and avc phenomena. Techniques of signal analysis are presented, followed by discussion of sound propagation, intensity distributions, and subjective and physiological responses to sound fields and sound field control.

Key Features

About the Authors

Mikio Tohyama

Mikio Tohyama holds a Doctorate of Engineering from Waseda University, Tokyo, Japan. Beginning in 1975 and for the next 18 years, Dr. Tohyama worked in research projects involving acoustics, vibration, and signal processing at the Nippon Telegraph and Telephone (NTT) Research Laboratories in Japan. From 1993 until 2003 he was professor at Kogakuin University, Tokyo, before moving to Waseda University, Tokyo, where he was professor of sound and auditory perception until 2012. In 2012 he founded a research consulting firm, Wave Science Study (WSS), which he still runs today. His present research interests are sound signature analysis oriented to sound field perception. Dr. Tohyama enjoys playing the piano every day.
