PURPOSE: To illustrate some principles of room acoustics as applied to music rehearsal rooms and concert halls.

DESCRIPTION: This tape includes examples of the effects of sound reflecting or absorbing surfaces, anechoic chambers, and reverberation time. A nice sequence replays a recording made in an anechoic chamber with various reverberation times, to illustrate the effect of the auditorium on the sound of a musical performance. The tape was produced as part of a package aimed at educators who are involved in the design of music rooms and concert halls.

SUGGESTIONS: This is a nice tape to play during a discussion of the effect of room acoustics on the sound of a performing group.

REFERENCES: (PIRA unknown.) See Demonstration Reference File for further information, including the book which accompanies this recording and discusses important aspects of room and auditorium design.

EQUIPMENT: Cassette tape with player.

SETUP TIME: None.
