Noise Output of Road Racing Motorcycles From Measured Leq Data


  • Andrew K. Mitchell School of Engineering, Acadia University, Wolfville, Nova Scotia


This paper reports the results of an experimental study of the noise output from road racing motorcycles competing in the Canadian Superbike race series. Leq data from single-point measurements are presented for five events, which are then analyzed to determine an energy-average noise output per competitor at each event. The analysis, which considers track geometry and total time spent on track by all competitors, seems to indicate a moderately rising trend in the noise output per participant over time that is attributed to the changing composition of the field. The single-number noise descriptor obtained is suggested as a useful tool for predicting noise levels at future events at this or other venues.
