标准范围
This International Standard specifies a method of measuring and calibrating the photoelectric outputfactor of single channel analogue photographic-type audio-level test films in all gauges, using a calibratingsound reproducer. It is applicable to both variable area- and variable density-type sound records with asilver audio track.It also specifies the performance of a calibrating audio reproducer.Calibrated audio-level test films are employed to measure the precise output level of photographic soundreproducers and the photoelectric output factor of different sound records. They are also employedto establish a reference level on a standard program level meter, should that be appropriate for theinstallation in use.
