This standard specifies the measurement methods and characteristic electroacoustic frequency response of the B-chain of motion-picture dubbing theaters, review rooms, and indoor theaters whose room volume exceeds 150 m3 (5297 ft3). It is intended to assist in standardization of reproduction of motion-picture sound in such rooms. It does not apply where the recorded sound is intended for reproduction under domestic listening conditions; i.e., for radio broadcasting, television broadcasting, tape, or disc. This standard does not cover that part of the motion-picture sound system from the transducer to the input terminals of the main fader, nor does it cover the electroacoustic response characteristic of motion-picture theater subbass loudspeakers (subwoofers).
