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:

1. Crawler Loader
2. Wheel Loader
3. Dumper
4. Tractor Scraper
5. Grader
6. Crawler Tractor with Dozer
7. Wheel Tractor with Dozer
8. Pad Foot Wheel Compactor with Dozer
9. Backhoe
10. Hydraulic Excavator
11. Log Skidder
12. Excavator &; Wheel Feller-Buncher
13. Pipelayer
14. Roller/Compactor
15. Trencher

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.
