摘　　要：随着工业、运输业、建筑业等行业的发展,噪声已经成为城市环境的突出问题。在噪声对人体的实验研究基础上,选取人的反应能力、操作准确度、工作效率为实验指标,选择70dB(A)、75dB(A)、80dB(A)、85dB(A)、90dB(A)、95dB(A)六个声级,让实验者个在不同噪声强度下完成反应能力、操作准确性、工作效率的实验若干次。再将实验数据用spss处理分析。由反应能力实验与人的效率实验可得,70dB(A)以上的噪声对人体的反应能力和人的工作效率都有影响,且噪声强度对两种能力的影响在85dB(A)后明显增大。由做题准确个数的实验可得,对于一些低难度重复率高的工作,只要操作者集中,70~95dB(A)的噪声对操作者工作准确度没有明显的影响。With the development of industry,transportation,construction and other industries,noise has become a prominent problem of urban environment.Based on the experimental study of noise on human body,human reaction ability,operation accuracy and work efficiency are selected as the experimental indexes,and six sound levels of 70dB(A),75dB(A),80dB(A),85dB(A),90dB(A)and 95dB(A)are selected to let the experimenters complete the several experiments of reaction ability,operation accuracy and work efficiency under different noise intensities for several times.Then the experimental data were processed and analyzed by SPSS.According to the reaction ability experiment and human efficiency experiment,the noise above 70dB(A)has an impact on human response ability and human work efficiency,and the impact of noise intensity on the two abilities increases significantly after 85dB(A).According to the experiment of the accurate number of questions,for some jobs with low difficulty and high repetition rate,as long as the operator is concentrated,the noise of 70~95dB(A)has no obvious impact on the operator's work accuracy.
