A Report on Listening Characteristics in 25 Danish Cinemas

Erik Rasmussen

A 35mm optical test film was produced with octave-filtered random noise. Played back five times with five different microphone positions in the auditorium, the average sound pressure level was calculated for each center frequency; mean and range values are given for 25 theaters and some specific samples are analyzed. Applying the ISO Draft Proposal (May 1969, Moscow), six theaters were within the boundaries, nine needed small modifications and ten were out on a large scale.
