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)
