Sound Visualization and Manipulation (ePub)

Unique in addressing two different problems - sound
visualization and manipulation - in a unified way

Advances in signal processing technology are enabling ever more
accurate visualization of existing sound fields and precisely
defined sound field production. The idea of explaining both the
problem of sound visualization and the problem of the manipulation
of sound within one book supports this inter-related area of
study. With rapid development of array technologies, it is
possible to do much in terms of visualization and manipulation,
among other technologies involved with the spatial distribution of
sound. This book aims to explore various basic functions for the
visualization and manipulation and demonstrate to the reader how
these properties determine the quality of visualization and
manipulation. The first half of the book introduces some basic and
general concepts and theories and the second part of the book
explains a number of techniques in sound visualization and
manipulation. It offers a unified presentation to two very
different topics - sound field visualization techniques based on
microphone arrays, and techniques for generation of controlled
sound fields using loudspeaker arrays. The authors emphasize the
similarities between these two physical problems and between the
mathematical methods used for solving them.

With extensive examples throughout the book, chapters include:
Acoustic Wave Equation and its Basic Physical Measures, Acoustic
Wave Equation and its Basic Physical Measures, Basic Theory of
Sound Visualization, Acoustic Holography, Beamforming, Basic Theory
of Sound Manipulation, Sound Focusing, and Sound Field
Reproduction.

* The first book to combine both the visualization and
manipulation of sound technologies in one comprehensive volume

* Presents the basic concepts using simple one dimensional cases
and then extends the concept to three dimensional cases, enabling
easier understanding of the fundamental concepts through the use of
minimum mathematics

* Provides a solid understanding of associated physics as well as
mathematical concepts for understanding the technologies,
addressing diffraction problems in an integrated format by using
Kirchhoff-Helmholtz integral equation

* Uses extensive examples demonstrating the benefits and
drawbacks of various applications, including beamforming and
acoustic holography
