Since 1929 The Journal of the Acoustical Society of America has been the leading source of theoretical and experimental research results in the broad interdisciplinary subject of sound. The Journal serves physical scientists, life scientists, engineers, psychologists, physiologists, architects, musicians, and speech communication specialists. Subject coverage includes: linear and nonlinear acoustics; aeroacoustics, underwater sound and acoustical oceanography; ultrasonics and quantum acoustics; architectural and structural acoustics and vibration; speech, music and noise; psychology and physiology of hearing; engineering acoustics, sound transducers and measurements; bioacoustics, animal bioacoustics and bioresponse to vibration. In addition to contributed papers, the Journal contains news items of interest to acoustical scientists, book reviews, references to contemporary papers in acoustics, reviews of acoustical patents, and news on the development of standards. Periodically the Journal also issues cumulative indexes of published articles.
