- 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.
