【Abstract】 A portable smart analyzer of tire tread noise has been developed on the basis of mutimedia.It can be used to measure the sound pressure level of tire tread noise with TNS/ODS analyzing and optimizing software.Three sound pressure levels are formed by introducing the wav sound file from the noise into A,B,C three-grade fuzzy weight network through two-level marking to carry out the analyses of time domain and frequency domain,and the evaluation of tire noise characteristics.更多还原
