Read an article today that Michigan DNR will be stepping up it's enforcement of noise levels on snowmobiles due to increased complaints from private landowners allowing trails through their land.
Just wanted to share the documented testing criteria in the article.
“For snowmobiles manufactured after July 1, 1977, and sold or offered for sale in Michigan, 78 decibels at 50 feet, as measured using the 2003 Society of Automotive Engineers standard J192. For a stationary snowmobile manufactured after July 1, 1980, and sold or offered for sale in Michigan, 88 decibels at 13.1 feet, as measured using the 2004 Society of Automotive Engineers standard J2567.”
