标准范围

本文件描述了一种客观确定环境噪声中音调可听性的方法。本文件旨在增强基于听觉印象的通常评估方法，特别是在对音调的可听程度没有一致意见的情况下。如果被评估的音调的频率等于或大于50？赫兹。在其他情况下，如果音调频率低于50？Hz，或者如果捕捉到其他类型的噪声（如尖叫声），那么这种方法就不能代替主观评价。笔记？该程序未在50以下验证？赫兹。本文提出的方法可用于自动工作的连续测量站。

This document describes a method for the objective determination of the audibility of tones in environmental noise.

This document 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 captured, then this method cannot replace subjective evaluation.

NOTE      The procedure has not been validated below 50 Hz.

The method presented herein can be used in continuous measurement stations that work automatically.
