The only real acoustics handbook for mechanical and architectural applications, this is a translation of the German standard work on the subject, written by an academic and an industrial practitioner. The book not only describes the state of art of engineering acoustics but also gives practical help to engineers for solving acoustic problems. It deals with the origin, the transmission and the methods of abatement of air-borne and structure-borne sound of different kinds – from traffic to machinery and flow induced sound.
