Feb., 1933] ACOUSTICS OF AUDITORIUMS 127 Conclusions. — To sum up the basic requirements for a reverberation control system for the continuous control of auditorium acoustics from a musical standpoint, we have: (a) Ease of operation. (b) The time required to pass from maximum to minimum reverberation should approach one second; a value less than this would impose too severe economic requirements. (c) The range of control should be a maximum, and be covered by steps, the number of which should be experimentally determined. (d) The operation of the equipment must produce no disturbing or distracting noises.
