Abstract
Overview
ISO 8687:1987 specifies standardized methods for measuring the signal-to-noise ratio (SNR) of variable-area photographic sound records on 8 mm Type S, 16 mm, and 35 mm motion-picture films. This standard from the International Organization for Standardization (ISO) details both a preferred and an alternative measurement method, ensuring consistent and reliable evaluation of the audio quality captured on film.
