Operational Sound Level Measurement Procedure for Snowmobiles
J1161_201711
This recommended practice establishes the instrumentation, test site, and test procedure for determining the exterior operational sound level for snowmobiles.
Rationale:
Sound pressure measurements on the operational test surfaces for snowmobiles have been known to vary as much as 6 to 10 dBA due to atmospheric, surface condition and vehicle fluctuation. The most recent update is focused on accounting for the the variability in the surface related variation.
