The Nature and Technology of Acoustic Space
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.
