Aircraft noise annoyance contours: Importance of overflight frequency
and noise level
Journal of Sound and Vibration, (1980)Abstract
Social survey studies to assess the presence of general annoyance
and activity disturbances were made in 38 areas around 9 airports.
The noise exposure was expressed as the number of overflights/24
hours and the dB(A) level from the noisiest aircraft type. An increase
in the number of overflights led to an increase in the extent of
annoyance and activity disturbances up to a level of 50 overflights.
The results indicate that the number of events is of limited value
in describing annoyance caused by aircraft noise exposure and that
the noise levels of noisy types of aircraft are more important. The
data suggest that a more accurate description and prediction of the
extent of annoyance in a population can be obtained by using the
dose-response relationships developed in this study.
