GB/T 15952-1995 in English

《GB/T 15952-1995个人声暴露计技术要求》由TC23（全国电声学标准化技术委员会）归口，主管部门为工业和信息化部（电子）。
本标准适用于测量稳态的、间断的、波动的、不规则的或脉冲声的A计权声暴露的仪器。本标准规定了一个准确度等级的个人声暴露计的声与电的性能要求。

Scope

Acoustic exposure is a physical measure of both the sound pressure and its duration at a given location by integrating the square of the instantaneous frequency-weighted sound pressure over time. This standard applies to instruments that measure A-weighted sound exposure to steady-state, intermittent, fluctuating, irregular or impulsive sounds. Instruments meeting the technical requirements of this standard are those intended to be worn on the human body to measure sound exposure. Measurement of sound exposure at workplaces Measure occupational noise exposure according to ISO1999 and ISO9612. This standard specifies the acoustic and electrical performance requirements for personal sound exposure meters of an accuracy class. The accuracy level of the corresponding integral sound level meter meets the type 2 requirements of IEC804:1985, and the A-weighted sound pressure level range is 80dB~130dB, and the nominal frequency range is 63Hz~8kHz. The tolerance for deviations in instrument performance from specified design objectives represents the performance level of a specific instrument. Personal acoustic exposure meters are required to operate within the tolerances of this standard for the specified range of environmental conditions.
