目的研究中等强度噪声条件下２ｈ暴露期间情绪状态的改变及其与受试者噪声敏感度和艾森克人格个性的相关关系。方法１４名男性受试者随机暴露于５０ｄＢ（Ａ）（对照），７５ｄＢ（Ａ）和８５ｄＢ（Ａ）２ｈ期间，于０．５ｈ，１ｈ和２ｈ进行ＰＯＭＳ问卷测试。结果“紧张”等不良情绪评分随噪声强度的增加而增加，精力充沛评分则下降。在２ｈ暴露期间，不良情绪评分逐渐增加，精力充沛评分则在０．５ｈ增加，１ｈ恢复至对照水平，以后又下降。在噪声暴露早期，噪声敏感度高的受试者其精力充沛评分较噪声敏感度低的受试者高；ＥＰＱ中Ｅ分与疲劳等不良情绪评分的增加值有正相关关系。结论噪声对受试者的情绪有一定的影响，其与受试者的噪声敏感度和艾森克人格个性有一定的关系。 Objective To study the changes of emotional state during 2h exposure under medium intensity noise condition and its correlation with noise sensitivity and Eysenck personality. Methods Fourteen male subjects were randomly assigned to receive either 50 dB (A) (control), 75 dB (A) and 85 dB (A) for 2 h. POMS questionnaires were performed at 0.5 h, 1 h, and 2 h. The scores of negative emotions such as “stress” increased with the increase of noise intensity, while those of energetic scores decreased. During the 2-hour exposure, the score of negative emotions gradually increased, while the energetic score increased at 0.5h, returned to the control level at 1h, and then decreased again. In the early stage of noise exposure, subjects with high noise sensitivity had higher energetic scores than those with low noise sensitivity. There was a positive correlation between the score of E and the increase of negative emotion scores such as fatigue in EPQ. Conclusion The noise has a certain influence on the emotion of the subject, which is related to the noise sensitivity of the subject and the personality of Eysenck.
