Abstract (en)
[origin: EP2177842A1] Sound-damping device for air vents or for breather pipes in rooms of buildings, characterized in that it comprises: - a frame (1, 6) designed to be fixed onto the end opening of a ventilation or breather pipe (T) in a manner suitably centred relative to the latter; - a covering element or cap (8) designed to be arranged on the said fixing frame (1, 6) and having a width suitably greater than the diameter of the opening of the said pipe (T) and situated at a distance from the latter so as to allow a sufficient amount of air to pass through; - at least one sound-absorbing means (7) which is arranged between said fixing frame (1, 6) and said cap (8) and which, in combination with these components, reduces and eliminates the incident and reflected sound waves which otherwise would reach the room of the building provided with said ventilation or breather pipe (T).
