In the following presentations, pertinent data on a number of facilities are presented to give some indication of the breadth in types of spaces and techniques which are being used to achieve qualified rooms. Data to be presented include: (1) size and shape of room; (2) description of rotating diffuser (if used); (3) room absorption (reverberation time versus frequency) and a discussion of modifications to the absorption if used; (4) general instrumentation used, and discussion of techniques used to obtain an estimate of space average sound pressure level; (5) a discussion of source position (s) used and their relationship to other characteristics of the space; (6) a brief summary of any unique or unusual problems encountered in the qualification of the facility.
