| 中文摘要: |
| 提出一种仿声方法，在由发声模型得到的声波波形数据基础上，经PCM编码、重新采样等处理，生成模拟室内测量和场地测量的标准格式的WAV 声音文件，在多媒体计算机中运行，对花纹噪声进行仿真，产生轮胎噪声，为噪声主观评价提供监听环境。与轮胎花纹噪声频谱的客观评价相结合，进行综合分析，可以替代传统的轮胎花纹噪声测量评价方法，实现花纹方案筛选，既节约试验费用，又大大缩短设计周期。 |
| 英文摘要: |
| A sound simulation system has been proposed. A WAV sound file simulating the indoor measurement and field measurement in the standard form is formed by PCM coding and resampling based on the data of sound wave shape from a sound-generating model. The file is processed on a multi-media computer to simulate the t read pattern noise for the subjective assessment . Combined with the objective assessment of the t read patten noise spect rum ，a comprehensive analysis of the subjective assessment can be used to replace the traditional assessement of the tread pattern noise for screening the tread pattern designs. The development cost is reduced and the design period is shortened by this method. |
