This thoroughly revised and long awaited new edition builds on the success of the 1991 third edition. This classic reference text considers the theory and practice of sound behaviour in closed spaces; a key area for acoustical engineers worldwide. It is of particular interest to those working on auditoria and will therefore stand as an excellent complement to Barron's Auditorium Acoustics. This new edition includes important new material on the growth of digital technology and sound intensity.

Product Description: An introduction into the methods of ultrasound generation and detection; and into the effects important for its propagation. Accessible to those without previous knowledge of general acoustics and will also serve as a useful student textbook.
