SAE J1166 Sound Measurement--Off-Road Self-Propelled Work Machines--Operator--Work Cycle

Product Code:SAE J1166
Title:Sound Measurement--Off-Road Self-Propelled Work Machines--Operator--Work Cycle
Issuing Committee:Sltc - Earth Moving Machinery Sound Level
Scope: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 stations 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 LoaderWheel LoaderDumperTractor ScraperGraderCrawler Tractor with DozerWheel Tractor with DozerPad Foot Wheel Compactor with DozerBackhoeHydraulic ExcavatorLog SkidderExcavator & Wheel Feller-BuncherPipelayerRoller/CompactorTrencherThe 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)(sub), 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.
