Acoustics - Objective method for assessing the audibility of tones in noise - Engineering method - First Edition
N PAS 20065
Annotation
This Publicly Available Specification describes a method for the objective determination of the audibility of tones in environmental noise.
This Publicly Available Specification is intended to augment the usual method for evaluation on the basis of aural impression, in particular, in cases in which there is no agreement on the degree of the audibility of tones. The method described can be used if the frequency of the tone being evaluated is equal to, or greater than, 50 Hz. In other cases, if the tone frequency is below 50 Hz, or if other types of noise (such as screeching) are to be captured, then this method cannot replace subjective evaluation.
The method presented herein can be used in continuous measurement stations that work automatically.

Акустика - Объективный метод для оценки слышимости тонов в шуме - Технический метод - Первый Выпуск
Эта Общедоступная Спецификация описывает метод для объективного определения слышимости тонов в экологическом шуме.
Эта Общедоступная Спецификация предназначается для увеличения обычного метода для оценки на основе слухового впечатления, в частности в случаях, в которых нет никакого соглашения по степени слышимости тонов. Описанный метод может использоваться, если частота оцениваемого тона равна или больше, чем, 50 Гц. В других случаях, если тональная частота ниже 50 Гц, или если другие типы шума (такие как визг) должны быть получены, то этот метод не может заменить субъективную оценку.
