摘要： 噪声的测量与评价是控制安检设备噪声质量的重要工作，本文在分析比较噪声评价指标的基础上，以EI-10080型安检设备为研究对象，实验分析安检设备噪声辐射声场的分布特点，提出用指定位置处噪声声压级对安检设备噪声进行测量和评价的方法，并且确定了2个测量点。实际测试表明，指定的2个测量点具有很好的代表性，同时该方法具有操作简单、测量精度高的特点。

Abstract: Testing and evaluation of noise are important work for the quality controlling of security inspection equipment. In this paper, some indexes for noise evaluation are analyzed and compared one another. As an example, the characteristic of the noise radiation distribution in the EI10080 security inspection equipment is analyzed experimentally. The method for testing and evaluation of noise of security inspection equipment is proposed by analyzing the sound pressure levels of noise at two prescribed points. Results of testing show that this method is easy to handle and has a high precision.

Key words: acoustics, security inspection equipment, noise, test, evaluation
