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. |
