Scope

This International Standard specifies the characteristics of the B-chain response of motion-picture studio dubbing theatres, review rooms and indoor theatres. It is intended to assist in the standardization of recording monitor and reproduction characteristics of motion-picture sound in rooms with volumes of at least 150 m. It does not apply where the recorded sound is intended for reproduction under domestic listening condi-tions, i.e. radio and television broadcasting, tape or disk. This International Standard does not cover the electro-acoustic response characteristic of motion-picture surround or effects loudspeakers, or sub-bass loudspeakers (sub-woofers).
