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.
