机场周围飞机噪声对教学活动的影响研究

Study of the effect on teaching by aircraft noise around airport

经调查得知 ,飞机噪声已严重影响了机场周围学校教学活动的正常开展 ,为此本文专门针对机场周围学校研究了飞机噪声的评价指标及教室室内飞机噪声限制标准 ,得出结论 :机场周围学校室内噪声的允许标准定为Leq≤ 5 5dBA ,LAmax≤ 6 5dBA .同时为消除同样等级的飞机噪声与其他交通噪声给人带来不同影响的差异 。

By investigation,aircraft noise has affected the teaching of schools around airport badly.So the paper specially researched the evaluation index and the threshold of aircraft noise inside the schools classrooms around airport.The paper concludes that a noise limit of L\-\{eq\} 55 dBA and L\-\{A max\} 65 dBA inside the schools classrooms is reasonable.At the same time,in order to eliminate the difference of effect of the aircraft noise and other traffic noises on human which are of the same grade,the paper puts forward a new method which can evaluate aircraft noise inside the schools classrooms around airport.
