THE RELATIONSHIP BETWEEN SUBJECTIVE AND OBJECTIVE RESPONSE DIFFERENCES AT DIFFERENT HEIGHTS ABOVE CINEMA SEATING

摘要

It has been customary to perform the calibration of the loudspeaker responses in cinemas with the measuring microphones placed at, or near, the height of the ears of the seated audience, in the belief that this would best represent the sound as actually heard, but the motives for doing this would appear to have been based on anecdotal evidence more than from specific testing. In the light of the fact that the cinema industry is currently looking at reassessing the whole subject of theatre calibration, this paper reports on a pilot study to investigate at which height the calibration microphones should be placed in order to best represent the most realistically-perceived sound quality.
