    Abstract - (Show below) - (Hide below)

    Establishes a method for determining the noise emitted by earth-moving machinery in terms of the A-weighted sound power level while the machine is working under dynamic test conditions. Covers field of application, references, definitions, instrumentation, test environment, measurement of equivalent continuous A-weighted sound pressure levels, acoustic measurements, calculation of A-weighted sound power level using equivalent continuous A-weighted sound pressure levels averaged over the measurement surface, information to be recorded, information to be reported and bibliography.
