Acoustics Measurement of Airborne Noise Emitted by earthmoving machinery Method for Determining Compliance with Limits for exterior noise Stationary Test Condition
This SAE Standard describes a method for determining the exterior noise emitted by earthmoving machinery in terms of the A-weighted sound power level while the machine is in a stationary test condition. at six positions on a hemispherical surface, the equivalent continuous a-weighted sound pressure levels are measured. The A-weighted sound power level of the machinery is calculated from the measured values.
