The physical value which best describes how strongly nocturnal aviation noise impacts on sleep is the maximum noise level. It shows to what extent the aircraft noise stands out from the existing background noises. The annoyance effect overall depends on the height and the frequency of occurring maximum noise levels.

The physical value which best describes how strongly nocturnal aircraft noise impacts on sleep is the maximum sound level of the overflight noise. The annoyance effect overall depends on the height and the frequency of occurring maximum sound levels.
