Abtract:
(1.1) This standard specifies the method of measurement of the photoelectric output factor of single photographic audio level test films in all film gauges, using a calibrating audio reproducer. It is applicable to both variable-area and variable-density audio records. (1.2) The standard also specifies the intended performance of a calibrating audio reproducer. (1.3) Calibrated audio-level test films are employed to measure the precise output level of photographic audio reproducers and the photoelectric output factor of different audio records, and to establish a reference level on a standard program-level meter appropriately chosen for the installation.
