INSTALLATION POUR LA VENTILATION NATURELLE D'UN LOCAL POURVUE D'UN AMORTISSEUR DE BRUIT
An apparatus for natural ventilation of a room, with a room delimited by walls. At least one door or one window includes a fixed stationary frame surrounding a movable opening frame, a ventilation passage provided on the door or the window and which communicates between the outside of the room and the inside of the room in such a way as to allow natural ventilation between the outside and inside of said room, and a noise absorber capable of attenuating sound waves propagating in the ventilation passage, the attenuation being realized by the generation of a counter-noise which is superimposed on the sound waves or by absorbing all or part of said sound waves.
