The book addresses the physical and physiological fundamentals, issues of room acoustics and measurement technology, including the relevant standards and guidelines needed in daily work in this field. It extensively covers questions of sound generation, air and structure-borne sound propagation, and noise reduction, as encountered in mechanical engineering, vehicle construction, as well as civil engineering. The individual contributions have been thoroughly revised, updated, and expanded. New sections include: active noise reduction (anti-noise), numerical methods, and sound generation in wood and metal processing.
