Specifies acoustical and electrical performance requirements for personal sound exposure meters of one accuracy grade. Applies to instruments for measurement of A-frequency-weighted sound exposure resulting from steady, intermittent, fluctuating, irregular or impulsive sounds. Coverage includes: latching overload indicator; sensitivity to various environments; response to unipolar pulses; linearity of response to steady signals. Also includes detailed definitions, annexes and tables.
