J1166_199005 SOUND MEASUREMENT - OFF-ROAD SELF-PROPELLED WORK MACHINES OPERATOR-WORK CYCLE

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(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:

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 statlon(s) is specified for L_eq(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.
