ACOUSTICS — MEASUREMENT OF AIRBORNE NOISE EMITTED BY EARTHMOVING MACHINERY — METHOD FOR DETERMINING COMPLIANCE WITH LIMITS FOR EXTERIOR NOISE — STATIONARY TEST CONDITION

1991-06-01
J2102_199106
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.

ACOUSTICS—MEASUREMENT OF AIRBORNE NOISE EMITTED BY CONSTRUCTION EQUIPMENT INTENDED FOR OUTDOOR USE—METHOD FOR DETERMINING COMPLIANCE WITH NOISE LIMITS

1991-06-01
J2101_199106
This SAE Standard describes a method for measuring the weighted sound pressure levels at prescribed microphone positions in the proximity of a device or machine for outdoor use, in order to determine compliance with noise limits. The A-weighted sound power level of the source is calculated from the measured values.
