This SAE Standard describes a method for determining the noise emitted to the environment by earthmoving machinery in terms of the A-weighted sound power level while the machine is working under dynamic test conditions.

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.
