ISO 7832:2014规定了使用校准声音复制器测量和校准所有仪表中单通道模拟摄影型音频电平测试胶片的光电输出系数的方法。它适用于具有银色音轨的可变面积和可变密度类型的录音。 它还规定了校准音频复制器的性能。

ISO 7832:2014 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.
