项目摘要

Validity of noise sensitivity scales was examined by a laboratory experiment and a field study. In the laboratory experiment, subjects were exposed to various pink noises and asked their annoyance. Dose-response relationships between noise level and individual annoyance reaction were obtained by means of logistic regression analysis. Individual noise sensitivity obtained from the experiments was compared with the score of Weinstein noise sensitivity scale obtained from a questionnaire which consisted of ten questions. It was found that the questionnaire of Weinstein noise sensitivity scale contained four inappropriate questions and that the modified questionnaire excluding the four questions was more appropriate to measure noise sensitivity. Moreover, the coding method of Weinstein noise sensitivity scale was improved in order to reduce the effect of over/under reporting. In the field study, questionnaires including Weinstein noise sensitivity scale were delivered to residents living along trunk roads. The answers from the residents indicated that the modified Weinstein noise sensitivity scale was more reasonable than the original scale.Dose-response relationships between noise level and the score of GHQ28 and QOL were analyzed considering noise sensitivity measured by the modified scale. The prevalence rate of neurosis diagnosed by GHQ28 showed significant increase by traffic noise, if the sensitive group was extracted from the sample based on the modified scale. This result means that application of noise sensitivity is efficient for the risk analysis of noise.

通过实验室实验和现场调查，对噪声敏感度量表的有效性进行了检验。在实验室实验中，受试者暴露在各种粉红色的噪音中，并询问他们的烦恼。通过Logistic回归分析，得出噪声水平与个体烦恼反应的剂量反应关系。将实验获得的个体噪声敏感度与由10个问题组成的问卷获得的Weinstein噪声敏感度量表得分进行比较。结果发现，Weinstein噪声敏感度量表问卷中有4个问题不合适，排除这4个问题后的改良问卷更适合测量噪声敏感度。此外，改进了Weinstein噪声敏感度量表的编码方法，以降低过报/漏报的影响。在现场调查中，向居住在沿着干道的居民发放了包括Weinstein噪声敏感度量表在内的问卷。居民的回答表明，改良的Weinstein噪声敏感性量表比原量表更合理，并结合改良量表测量的噪声敏感性，分析噪声水平与GHQ 28和QOL评分的剂量-反应关系。若以改良量表为基础提取样本中的敏感人群，则GHQ 28诊断的神经症患病率明显高于交通噪声。这一结果表明，噪声敏感度的应用是有效的噪声风险分析。
