Formulas of Acoustics

This collection of formulas has been written by applied scientists and industrial engineers for design professionals and students who work in engineering acoustics. It is subdivided into the most important fields of applied acoustics, each dealing with a well-defined type of problem. It provides easy and rapid access to profound and comprehensive information. In order to keep the text as concise as possible, the derivation of a formula is described only as far as necessary for its understanding. The interested reader can refer to the original source of the result. In addition to formulas, useful principles and computational procedures are given.

Professor Dr. F. P. Mechel, born in 1930 in Blickweiler, Germany, studied Applied Physics in Mainz, Heidelberg, and Goettingen. After his doctoral thesis (1959) he worked for many years as a researcher, first in Applied Physics and later in Acoustics. In 1971 he became a professor at Saarland University. At the same time he was head of the R&D department of a major corporation. In 1977 he became the Head of the Fraunhofer Institute for Building Physics in Stuttgart, where he retired in 1990. Since 1990 Professor Mechel has been an active hobby scientist.

F. P. Mechel is author of numerous articles, six books as well as co-author and co-editor of four handbooks on Acoustics.
