摘要：设计基于多媒体的轮胎花纹噪声智能测量分析仪，应用TNS/ODS分析优化软件，可测量轮胎花纹噪声的声压级。将噪声形成wav音频文件，通过二级定标引入A，B，C三档模糊（Fuzzy）计权网络，生成3档声压级，可执行时域、频域分析以及轮胎噪声性能评判。

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.
