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.

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.

Sound Measurement—Off-Road Self-Propelled Work Machines Operator-Work Cycle

1998-10-01
HISTORICAL
J1166_199810
This SAE Standard sets forth the procedures to be used in measuring sound levels and determining the time weighted sound level at the operator's station(s) of specified off-road self-propelled work machines. This document applies to the following work machines which have operator stations as specified in SAE J1116: Crawler Loader Wheel Loader Dumper Tractor Scraper Grader Crawler Tractor with Dozer Wheel Tractor with Dozer Pad Foot Wheel Compactor with Dozer Backhoe Hydraulic Excavator Log Skidder Excavator and Wheel Feller-Buncher Pipelayer Roller/Compactor Trencher Sweeper The instrumentation requirements and specific work cycles for these machines are described. The method used to calculate the time weighted average sound level at the operator station(s) is specified for Leq(5), or optional exchange rates, during continuous operation in a work cycle. A method to relate the time weighted average sound level at the operator station(s) to operator sound exposure is also provided.

The method used to calculate the time weighted average sound level at the operator statlon(s) is specified for Leq(5), or optional exchange rates, during continuous operation in a work cycle. A method to relate the time weighted average sound level at the operator statlon(s) to operator sound exposure is also provided.
