The effects of noise on information processing in perceptual and memory tasks, as well as time reaction to perceptual stimuli, were investigated in a laboratory experiment. Performance and heart rate in Information Processing Test, Simple and Choice Reaction Time tests and Stroop's test were evaluated at three levels of noise (silence, 75 dBA, 95 dBA). Individual noise sensitivity and noise-induced temporary threshold shift (NITTS) were also assessed. The results show that neither noise nor individual noise sensitivity, or NITTS, as separate factors have an influence on information processing and time reaction to perceptual stimuli. However, noise effects simple reaction time in interaction with individual noise sensitivity, and information processing--within experimental session duration. Experimental session duration was the one separate factor affecting information processing. Noise as a separate factor does not have an influence on task performance, however, it affects heart rate. The higher increase of noise-induced temporary threshold shift, the smaller the number of heart beats/minute was found.
在一项实验室实验中，研究了噪声对感知和记忆任务中信息处理以及对感知刺激的时间反应的影响。在三种噪声水平（安静、75分贝、95分贝）下，评估了信息处理测试、简单反应时间测试、选择反应时间测试和斯特鲁普测试中的表现和心率。还评估了个体噪声敏感性和噪声诱发的临时阈移（NITTS）。结果表明，噪声、个体噪声敏感性或NITTS作为单独因素，均不会对信息处理和对感知刺激的时间反应产生影响。然而，在与个体噪声敏感性的相互作用中，噪声会影响简单反应时间，并且在实验时段持续时间内会影响信息处理。实验时段持续时间是影响信息处理的一个单独因素。噪声作为单独因素不会对任务表现产生影响，但是会影响心率。发现噪声诱发的临时阈移增加得越高，每分钟心跳次数就越少。
