Measurement of Exhaust Sound Levels of Stationary Snowmobiles
This SAE Recommended Practice establishes the test procedure, environment and
instrumentation for determining the sound levels of snowmobiles in the stationary test mode.
This test method is intended to provide an accurate measurement of exhaust and other engine
noise and may be used to evaluate new and in-use snowmobiles to determine compliance with
noise control regulations. Sound level measurements obtained with this test method are not
intended as an engineering determination of overall machine noise. For this purpose, the use
of SAE J192 is recommended.
