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. 0aAcoustics. 0aFourier analysis. 0aArchitectural Acoustics.14aAcoustics.24aFourier Analysis.24aArchitectural Acoustics.2 aSpringerLink (Online service)0 tSpringer Nature eBook08iPrinted edition:z978303167809708iPrinted edition:z978303167811008iPrinted edition:z978303167812740uhttps://doi.org/10.1007/978-3-031-67810-3
