N2 - A measuring technique for tire-pavement interaction noise that uses a novel close proximity(NCPX) method equipped with surface microphones has been employed to perform pavement noise evaluations on different pavement sections. Through field tests, the appropriate noise-measuring procedures have been developed and proofed for evaluating pavement surfaces at varying vehicle speeds. Results show that tire-pavement noise levels vary widely according to the various surface types, vehicle types, and vehicle speeds. In addition, power-by noise (power- Train plus tire-pavement interaction noise) measurements, based on the NCPX method, were found to be applicable to the prediction model used for outdoor sound propagation.
