基于多因素噪声模糊综合评价方法的研究及应用

Studies on the Method of the Noise Fuzzy Comprehensive Assessment Based on Many Factors,and It's Application

以往的噪声评价是基于A声级进行的,缺乏对人的心理和除听力以外的其它生理因素的考虑。因此,文章在传统的噪声评价研究的基础上,建立具有创新意义的由听力损失、心率变异和脑波组成的多因素噪声模糊评价系统,进行噪声对人体负荷综合影响的评价。经过标准噪声人机实验的验证分析,得到结论:多因素的评价方法较传统方法更符合实际影响情况。

The traditional assessment of noise is based on A noise level, which lacks the consideration of the influence of the noise on human＇ s psychological and physiological factors besides hearing. So, this paper creatively established a many - factor fuzzy assessment system of noise, based on the traditional researches on the assessment of noise, to assess the comprehensive influence of noise on human body＇ s loads, the assessment system consists of hearing loss, heart rate variability（HRV） and EEGs. The data from the standard human -machine experiments are used to validate the new assessment system. The result shows that, the influence of the fuzzy assessment method on the basis of many factors, is more matching practice than that of the traditional method.
