What are two strategies on how airports can mitigate noise?

In the present study, six noise reduction strategies including the optimization of aircraft type, regulation of number of night flights, flight procedure, modification of operating runway, land use planning and the installation of sound insulation windows were proposed to reduce the impacts of aircraft noise on the ...
