摘　　要：从轮胎花纹的时域波形中提取信息 ,运用 16位PCM编码生成WAV格式的声音文件 ,用多媒体设备播放 ,并加入背景噪声 ,实现轮胎花纹噪声的微机仿真发声。试验证明 ,模拟噪声与实测噪声非常接近 ,多普勒效应十分逼真 ,为轮胎噪声主客观评价提供了经济的试验环境与有效的手段。The information was collected from the time domain waveform,and then formed a sound file in WAV format by using sixteen digi PCM code, which was transmitted on a multi media device with the background noise to realize the computer sound emission for simulating the tread patterns noise.It was confirmed through the test that the simulated noise was very close to the measured noise,the Doppler effect was really true,and thus a economic test environment and an effective tool for the subjective and objective assessment of tire noise were obtained.
