标准范围
This International Standard specifies the measurement methods and characteristic electroacousticfrequency response of the B-chain of motion-picture dubbing theatres (mixing rooms), screeningrooms, and indoor theatres whose room volume exceeds 125 m3 (4,414 ft3). It is intended to assist instandardization of monitoring and reproduction of motion-picture sound in such rooms. The goal is tohave constant perceived loudness and frequency response from installation to installation, and fromposition-to-position within an installation. This International Standard does not cover that part of themotion-picture sound system extending from the transducer to the input source audio selector.
