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 dB ( 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 study the effect of short-term steady noise with moderate level on task performance and annoyance , 49 male volunteers served as the test subjects and performed the tests of task perfomance and the scale of noise annoyance under quiet control and noise conditions .The noise SPL was 88 dBA and exporsure time was 1h.The tests of task performance involved circling numbers , subtrac-tion, memory, 80-8 scale test and Dual Task .The results showed that , during the noise exposure , the score of circling numbers was slightly decreased , accurate rate of memory had little change , ac-curate rates of calculation and 80-8 test were decreased , the error mean of time eatimation in dual task was increased , but all these changes were not significant .The score of noise annoyance in-creased significantly under noise , and the score of noise annoyance had some correlativity with that of Weinstein noise sensitivity questionnarie .
