Maximum Exterior Sound Level for Snowmobiles
- Ground Vehicle Standard
- J192_201103
- Revised
Scope
This SAE Recommended Practice establishes the instrumentation, test site, and test procedure for determining the maximum exterior sound level for snowmobiles.
Sound propagation is directly related to the ground cover and provides the largest variation to the measured result. A correction factor is introduced to improve year round test repeatability of the results on grass surfaces by correcting their spectra to be similar to snow covered ground spectrums.
Measured sound pressure levels are also highly dependent on the degree of track slip present when performing the vehicle acceleration. Operators should attempt to limit track slip as much as possible while maintaining the requirements described in 5.1.1.

Issuing Committee
Snowmobile Technical Committee
The Snowmobile Technical Committee develops and maintains SAE Standards, Recommended Practices, and Information Reports related to snowmobiles and their components or systems. The committee also maintains liaison with groups such as the Snowmobile Safety and Certification Committee, Inc. (SSCC), Transport Canada, the Canadian Standards Association (CSA), SAE-related committees and other organizations as necessary. Participants in the SAE Snowmobile Technical Committee include OEMs, suppliers, consulting firms, government and other interested parties.
