This document specifies a precision laboratory NORDTEST method of measuring reverberation times according to the interrupted noise method. The document establishes directions for reference measurements which could be used, for example, as a common basis for the verification of other reverberation time measurement methods.
This document applies to computer-controlled equipment and to measurement set-ups where the decay evaluations are made by a computer. The computer may be an internal microcomputer in a seif-contained instrument or a separate minicomputer combined with the necessary instruments for generation and analysis.
