Physical Approach to Engineering Acoustics : Second Edition

This updated edition adds new material on the acoustics of mufflers and ducts, including a new analysis on sound propagation in a duct having a cross sectional area that varies in the direction of the duct length. The textbook retains its class-tested fundamentals of engineering acoustics and examination of in-depth concepts within the domains that apply to reducing noise, measuring noise, and designing microphones and loudspeakers. The book particularly emphasizes the physical principles used in designing miniature microphones. These devices are used in billions of electronic products, most visibly, cell phones and hearing aids, and enable countless other applications. Distinct from earlier books on this topic that take the view of the electrical engineer analyzing mechanical systems using electric circuit analogies. © Springer
