Simulation and Measurement of Tire Tread Pattern Noise

The tread patterns noise of different tire were simulated with TPN tire tread pattern noise simulation system developed by Wuhan University of Technology,and the simulation results were compared with testing data.Since the measured noise included non-pattern noise,the 1/3 octave band histogram of measured noise had some difference with the simulated result.However,the mea-sured A-weighted sound pressure levels of tire noise were basically in the same trend with the simulated results.
