The paper studies the relations between A-weighted sound exposure level indoor and awakenings or arousal,and proves that it is necessary condition of setting threshold of single-event aviation noise at night. The author recommends Lse=90dB as limit of single-event aviation noise at night.The conclusion has worthy of utilities and is significant of engineering.%文章通过对室内A计权声暴露级与睡眠唤醒率及扰眠率之间关系的研究,证明了设置 夜间单个事件飞机噪声限制标准的必要性,并近似拟定100dB的室外A计权声暴露级作为夜间单个 飞机噪声事件的限制标准。文章具有一定的适用价值和工程意义。
