Cinematography - Method of measurement of perceived loudness of short duration motion-picture audio material - Second Edition
N 21727
Annotation
This International Standard specifies a method of measurement of short duration motion-picture sound that allows assessment of the subjective loudness and annoyance of the sound recording when replayed at the recommended replay level in rooms aligned with the characteristics of ISO 2969. The specified method of measurement assesses the entire duration of the sound recording, typically commercials and trailers that do not exceed 3 min in length, with suitable channel summation, frequency weighting and time integration. It does not specify a maximum recommended level for such material and is solely aimed at describing a measurement method.
NOTE Typical recording and replay levels are discussed in Annex A.

Кинематография - Метод измерения воспринятой громкости кратковременный материал аудио кинофильма - Второй Выпуск
Этот Международный стандарт указывает метод измерения кратковременный звук кинофильма, позволяющий оценку субъективной громкости и раздражение из-за звукозаписи, когда переигрывается на рекомендуемом уровне переигровки в комнатах, согласованных с особенностями ISO 2969. Указанный метод измерения оценивает всю продолжительность звукозаписи, обычно реклама и трейлеры, не превышающие 3 минуты в длине, с подходящим суммированием канала, весовым коэффициентом частоты и интеграцией времени. Это не указывает максимальный рекомендуемый уровень для такого материала и только нацелено на описание метода измерения.
