Ltd., Chennai, on acid-free PrefaceThis book is a research monograph on acoustics from a signal theoreticalpoint of view. Namely this book describes the elementary nature of soundwaves and their signal theoretic signatures, which are very informative munication. Essential issues about sound ?elds in closed space are dealtwith according to classical wave physics and linear system theory, on whichdiscrete signal analysis is based. Very introductory levels of university physicsand mathematics, and fundamental formulations of digital signal analysis areassumed as preknowledge, but most of the issues are discussed in detail soas to be self-contained in this book as much as possi
