Funktionelle Akustik - Die Nachhall-Charakteristik des Raumes als Basis für seine Nutzbarkeit

Functional acoustics — useability of rooms based on reverberation characteristics. Part 2: Bass foundation and frequency spectrum of reverberation.

In Part 1 of this series the present working conditions for a functional room-acoustic design were outlined. The prevailing doctrines, standards and preoccupations were critically questioned which are cultivated by acousticians with respect to the desirable reverberation of rooms of differing size and use. Frequent problems were identified at the low frequencies especially in small, but also in large rooms. Here the often depreciated relevance of the bass regime will be underlined by further citations. A church room which is highly esteemed by musicians and sound engineers for its outstanding acoustical quality demonstrates the positive influence of a suppression of the reverberation at the low and simultaneous enhancement at the high frequencies on the performance and recording of speech and music. Numerous users of this room support these conclusions with their professional sensations.
