From the reviews of the fifth edition:

“The present book is a translation of the fifth German edition published in 2004. The translator, Uwe Hansen, deserves praise for the quality of his writing in the English language. … Given the material in this text, orchestral musicians and conductors can … appreciate how to use any given acoustical space most advantageously and acousticians and architects can optimize the spaces in which musical groups perform. … The book will certainly benefit all those involved with musical performance.” (Leo Beranek, International Journal of Acoustics and Vibration, Vol. 14 (2), 2009)

“The abundance of easy to understand graphic illustrations help the reader go through the relatively complex subjects. The writing is easy to read … . The quality and quantity of illustrations (some of them color plates) are exceptional. … A well written subject index helps find subjects of interest to the reader. There is also a composer-composition index at the end of the book. In summary, this is a highly recommended valuable book for professionals as well as for students interested in musical performance.” (Alberto Behar, Noise Control Engineering Journal, Vol. 58 (5), September-October, 2010)
