| 中文摘要: |
| 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。 |
| 英文摘要: |
| 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. |
