Trail bike noise research 2010 Australia


“This paper describes recent research into noise emissions from trail bikes. A review of relevant noise control regulations is provided, covering the operation of trail bikes across Australia, and including regulations specific to the State of Victoria. Initial investigations comprised stationary noise testing a selection of typical bike and exhaust configurations, conducted under controlled conditions and according to standardised test procedures applicable to each regulatory framework. Results from these initial measurements indicated substantial variance between noise levels obtained according to different test procedures, even where the relevant noise limit is identical.”
