    Abstract - (Show below) - (Hide below)

    Provides for four types of meter, viz. Types 0 and 1 for laboratory and precision use, Type 2 for general field applications, and Type 3 for field noise survey applications, with one or more frequency-weighting characteristics A, B and C and one or more time-weighting characteristics S, F, I and P. Specifies the directional frequency-weighting and amplifier, time-weighting, detector and indicator characteristics, and sensitivity to various environments, and includes electrical and acoustical tests. Is technically equivalent to IEC 651 and includes an annex showing deviations from IEC 651.

    Scope - (Show below) - (Hide below)

    This Standard specifies requirements for sound level meters for the measurement of certain frequency-weighted and time-weighted sound pressure levels. This Standard specifies the following characteristics of sound level meters: (a) Directional characteristics.(b) Frequency-weighting characteristics.(c) Time-weighting, detector and indicator characteristics. (d) Sensitivity to various environments.It also sets out electrical and acoustical procedures to verify compliance with the characteristics specified and describes the method for absolute sensitivity calibration.
