| 摘 要： | 本文从环境卫生学和行为毒理学的角度，研究了学校噪声的来源、污染现状及其对实验动物和中小学师生行为的影响。结果表明，学校噪声污染严重，等效声级平均为６２ｄＢ（Ａ），超过６５ｄＢ（Ａ）的学校占被调查学校的３３．３％。噪声主要来源于交通噪声。根据行为毒理研究结果，提出学校室外１ｍ噪声标准的建议值（Ｌｅｇ）为５５ｄＢ（Ａ）。本研究为制订学校噪声标准和噪声防治提供了科学依据。

| Abstract: | In this paper,Outdoor noise in school and some effect of noise was studied by means of environmental health and behavioral toxicology. The result shows that outdoor noise pollution in school was very serious,the average of equivalent sound level (Leq)was 62 dB (A)and the percentage of schools (Leq beyound 65dB (A))was 33.3%. The main source is traffic noise.Acording to the results of behavioral toxicological study,outdoor noise standard in school is suggested to be 55dB (A). Our research has certain reference value in enacting standard and prevention of noise. |
