EMPRIICAL MODEL FOR PREDICTING IN-SERVICE TRUCK TIRE NOISE LEVELS

SAE Recommended Practice J57a--Sound Level of Highway Truck Tires--specifies a simple, practical noise certification test procedure for tires which results in a single-number rating--maximum A-weighted sound level--of the coastby sound level measured according to prescribed procedures. Such a rating by itself, however, does not allow prediction of in-service noise levels. This report discusses the basic assumptions and necessary input data for a DOT/NBS developed empirical model which utilizes the certification test results to predict in-service noise levels. The usefulness and expected accuracy of the predictive model are shown through a comparison of measured versus predicted maximum A-weighted sound levels for a variety of truck/tire combinations. /GMRL/
