Aircraft noise and times of day: possibilities of redistributing and influencing noise exposure.
Disturbing effects of aircraft noise depend on the time of day at which the sound sources emerge. The reason can be seen in different human activities which vary qualitatively throughout the day. Especially in the evening and during the night people are more sensitive against noise induced disturbances which is a result of several field studies. Additionally there exists empirical evidence that human performance behaviour profits by keeping the night period free of sound exposure. As a consequence of these findings it is discussed whether the existing air traffic should be rescheduled to the daytime. It is argued that not only noise rescheduling needs to be considered, but also the spatial redistribution of air traffic volume. In using a mix of rescheduling techniques and administrative possibilities, significant reductions of aircraft noise exposure can be achieved.
