| 摘 要： | 环境噪声问题正在逐渐受到重视，针对工程机械环境噪声各测点A声级读数彼此相差达到5dB(A)以上时的情况，通过分析，提出了不可简单求取算术平均值，而应求取表面平均A声级作为评定指标的结论。

| Abstract: | The problem of environmental noises is being valued gradually.According to the difference of each measuring point of construction equipment,which is over 5dB(A),this paper gives the result that we cannot only use average value,we should regard the surfacing average noise level of a grade as evaluating index. |

| Keywords: | environmental noise evaluating index average voice level of a grade in surface |
