为探讨短期噪声暴露对男性受试者绩效及烦扰度的影响,49名男性受试者在88 d B(A)的噪声下暴露1小时,期间进行绩效测试及烦扰度量表调查,绩效测试包括圈数字、心算、记忆力、80-8测试及双重任务测试。实验结果表明,较对照数据而言,噪声下圈数字得分略下降,给定时间内心算正确率下降,工作记忆力正确率基本不变,80-8量表测试正确率下降,双任务测试时间估计误差均值提高,上述变化均不具显著性,受试者烦扰度分值在噪声下明显提高,并与Weinstein噪声敏感性问卷得分具有相关性。
To investigate the effect of short-term noise exposure on performance and disturbance of male subjects, 49 male subjects were exposed to noise for 88 d B (A) for 1 hour during which performance tests and disturbance scale surveys were conducted. Performance tests included Circle figures, mental arithmetic, memory, 80-8 test and dual mission test. The experimental results show that compared with the control data, the numerical score of the ring under the noise decreases slightly, the accuracy of mental arithmetic decreases within a given time, the accuracy of working memory remains basically unchanged, the accuracy of the 80-8 scale test decreases, the dual task test time estimate The error mean value increased, the above changes were not significant, subject annoyance score significantly increased under noise, and with the Weinstein noise sensitivity questionnaire score correlation.
