Acoustics

Essential concepts theory and models of linear acoustics for engineers. This book introduces the basic concepts theory and models of linear acoustics for engineers. Part one develops the theoretical framework (wave equations Fourier theory Helmholtz equation) and introduces key concepts (pressure velocity impedance intensity power sound levels). Part two proposes a systematic review of the fundamental physical mechanisms of acoustics and discusses the associated mathematical models: reflection absorption resonance guided propagation radiation diffraction refraction propagation in dissipative media convected propagation atmospheric propagation fluid-structure interaction sound transmission and insulation.
