Abstract
A given film often sounds different in different cinemas, and different from the way it sounded in the dubbing theater. Strict adherence to some purely electrical response does not insure identical sound in different theaters. Loudspeaker and auditorium properties must also be included. Described here is work done in Sweden during the last four years. A logical division of the theater replay chain in two parts is introduced, enabling a generalized treatment to include also control-room monitoring. Steady-state, filtered-noise measurement methods are described and it is shown that simple octave-filtered noise gives a very appreciable amount of information. Results from a number of cinemas and control rooms are given, together with suggestions for recommended response curves and some notes on beginning international standardization.
