中文名称：声学 护耳器 第2部分：护耳器磨损时有效声压等级（A级标准）的评定

英文名称：Acoustics — Hearing protectors — Part 2: Estimation of effective A-weighted sound pressure levels when hearing protectors are worn

发布日期：1994-08

标准范围

描述了三种方法（倍频程法、HML法和SNR法）来估计佩戴听力保护器时有效的A加权声压级。这些方法适用于噪声的声压级或等效连续声压级。虽然这些方法主要用于稳定的噪声暴露，但也适用于含有脉冲成分的噪声。它们不适用于峰值声压级测量。

Describes three methods (the octave-band, HML and SNR methods) for estimating the A-weighted sound pressure levels effective when hearing protectors are worn. The methods are applicable to either the sound pressure level or the equivalent continuous sound pressure level of the noise. Although primarily intended for steady noise exposures, the methods are also applicable to noises containing impulsive components. They are not suitable for use with peak sound pressure level measurements.
