The effect of the number of aircraft noise events on sleep quality

Background Both the WHO and the EC recommend the use of Lnight as the primary indicator for sleep disturbance. Still, a key question for noise policy is whether the prediction of sleep quality could be improved by taking the number of events into account in addition to Lnight. Objectives The current paper investigates the association between...

A barrier for low frequency noise from starting aircraft: Comparison between numerical and scale model results

Amsterdam Airport Schiphol has organized a competition to design a noise mitigating measure along the 'Polderbaan' runway. Its main goal is to reduce the low frequency (LF) ground noise from starting aircraft. The winning concept is a flexible parabolic shaped noise barrier positioned relatively close to the runway. There is a large distance...
