The Blue Ridge Parkway National Park provided an environment where sound level

measurements could be made for numerous motorcycle pass-by events. Data were examined

for five motorcycle categories: cruiser, sport, dual purpose, touring, and

moped/scooter, in terms of broadband sound levels and on a spectral basis (one-third

octave bands). Then the cruiser category was examined further since these motorcycles

generated the loudest and some of the quietest measured sound levels. Initial

investigations were made for the following: sound levels for groups of motorcycles,

sound levels at sensitive receiver locations, and predictions of sound levels using

five motorcycle categories in a special research version of the FHWA Traffic Noise

Model® (TNM®).
