Written by a noted authority in the subject area, Ingard's Acoustics is a comprehensive study of the theory and practical application of acoustics to numerous fields. It may be used as a reference by scientists and engineers or as a senior-undergraduate or graduate-level course. Several of the chapters include notes and numerical results from the author’s involvement in specific projects, and contain hitherto unpublished material. Items in this category are aero-acoustic instabilities, flow interaction with acoustic resonators, sound propagation in the atmosphere, sound generation by fans, aspects of nonlinear acoustics, the analysis of an oscillator with “dry friction,” and a discussion of the frequency response of the ear.
