Cinematography. Photoelectric output factor of photographic-type audio-level test films. Measurement and calibration Ingestion-build-100998 Noise test code for grinding1 Scope This International Standard specifies a method of measuring and calibrating the photoelectric output factor of single channel analogue photographic type audio level test films in all gauges, using a calibrating sound reproducer. It is applicable to both variable area and variable density type sound records with a silver audio track. It also specifies the performance of a calibrating audio reproducer. Calibrated audio level test films are
