The Institute of Aerospace Medicine at the German Aerospace Center (DLR) investigated the influence of nocturnal aircraft noise on sleep in polysomnographic laboratory and field studies between 1999 and 2004. The results of the field studies were used by the Regional Council of Leipzig (Germany) for the establishment of a noise protection plan in the official approval process for the expansion of Leipzig/Halle airport. Methods and results of the DLR field study are described in detail. Special attention is given to the dose-response relationship between the maximum sound pressure level of an aircraft noise event and the probability to wake up, which was used to establish noise protection zones directly related to the effects of noise on sleep. These protection zones differ qualitatively and quantitatively from zones that are solely based on acoustical criteria. The noise protection plan for Leipzig/Halle airport is presented and substantiated: (1) on average, there should be less than one additional awakening induced by aircraft noise, (2) awakenings recalled in the morning should be avoided as much as possible, and (3) aircraft noise should interfere as little as possible with the process of falling asleep again. Issues concerned with the representativeness of the study sample are discussed.
德国航空航天中心（DLR）的航空航天医学研究所于1999年至2004年间，在多导睡眠图实验室和实地研究中调查了夜间飞机噪音对睡眠的影响。德国莱比锡地区议会在莱比锡/哈雷机场扩建的官方审批过程中，将实地研究结果用于制定噪音保护计划。详细描述了DLR实地研究的方法和结果。特别关注飞机噪音事件的最大声压级与醒来概率之间的剂量反应关系，该关系用于建立与噪音对睡眠影响直接相关的噪音保护区。这些保护区在质量和数量上与仅基于声学标准的区域不同。介绍并论证了莱比锡/哈雷机场的噪音保护计划：（1）平均而言，飞机噪音引起的额外觉醒应少于一次；（2）应尽可能避免早上回忆起的觉醒；（3）飞机噪音对再次入睡过程的干扰应尽可能小。讨论了与研究样本代表性有关的问题。
