Defines procedures for measuring reverberation time in rooms. In addition to auditoria or concert halls, it also applies to rooms meant for speech and music, or where noise protection is an issue. Covers measurement method, required apparatus and coverage, and evaluation procedure for data and presentation of the test report.
