789 - Active/passive facade insulation againsts aircraft noise
Jacques R., Julien M., Remi L.
Abstract
The transmission of aircraft noise inside a building is generally dominated by the transmission through windows. An improvement of insulation consists in provinding a hight insulating window. This solution is suitable as far as no ventilation to refresh the internal air during summer time is required. A solution is to use airconditionning during hot periods, but it is energy consuming. An alternative is, in addition to a hight insulating window, to provide a large aperture with very low pressure drop to allow natural ventilation, but with hight insertion loss. This can be obtained at hight frequencies by passive treatement, and at low frequencies by an active device. The author will present a practical and efficient realisation installed in houses situated close to LYON airport and MILANO airport. The technique used and the results obtained with real aircraft will be presented. This research called 'TERIA'is supported by the European Commision in the Interreg MEDOC program. called 'TERIA
