This recommended practice establishes the instrumentation, test site, and test procedure for determining the exterior operational sound level for snowmobiles. 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.
