    Describes the characteristics of the B-chain response of motion-picture studio dubbing theatres, review rooms and indoor theatres. Assists in the standardization of recording monitor and reproduction characteristics of motion-picture sound in rooms with volumes of at least 150 cubed metres. Recorded sound for reproduction under domestic listening conditions, i.e., radio and television broadcasting, tape or disks.
