This test method describes the procedures for measuring tire/pavement noise using the on-board sound intentisy (OBSI) method and the procedures for verification of the measurement system. The test method provides an objective measure of the acoustic power per unit area at points near the tire/pavement interface.The on-board sound intensity measurement method described herein permits the tire/pavement sound intensity to be measured directly and allows various pavements and textures to be directly compared.This method is expected to be subject to considerable and rapid change as experience increases and research results are implemented.
