Phase analysis, i.e., investigations of zeros of transfer functions, is a qualitative or system theoretic approach to sound fields rather than the wave-theoretic power spectral analysis. The examination of phase responses offers new insights into sound fields and yields results that the standard power spectral analysis cannot provide. This book presents experimental data and numerical examples based on the mathematical formulations. It shows the mathematical formulations of acoustics and communication systems for engineers and physicists to get familiar with the basics of science. Chapters 1?5 provide the theoretical basis on the system theoretic approach to sound fields where Chapters 1 and 2 are introductions to discrete acoustic systems, Chapters 3?5 summarize wave equations, geometrical and random theories of room acoustics, and Chapters 6?10 develop details of transfer functions in sound. 606 $aAcoustics 606 $aFourier analysis 606 $aArchitectural acoustics 606 $aAcoustics 606 $aFourier Analysis 606 $aArchitectural Acoustics 615 0$aAcoustics. 615 0$aFourier analysis. 615 0$aArchitectural acoustics. 615 14$aAcoustics. 615 24$aFourier Analysis. 615 24$aArchitectural Acoustics. 676 $a534 700 $aTohyama$b Mikio$0283589 801 0$bMiAaPQ 801 1$bMiAaPQ 801 2$bMiAaPQ 906 $aBOOK 912 $a9910896183403321 996 $aPhase Analysis of Sound Fields$94212525 997 $aUNINA
