Abstract (en)
[origin: WO2009071963A1] The air intake (1) for establishing atmospheric communication between a first area (V1) and a second area (V2) separated by at least one wall (10) and connected by means of a ventilation system or duct comprises a boxlike body (20) provided with first and second apertures (30, 40) interconnected by a ventilation channel (22) which passes through the said boxlike body and which allows a flow of air to pass between the said first and second areas (V1, V2), and comprises at least one silencing device (50) located inside the said boxlike body (20), to damp any sound waves carried by the air flow passing through the said ventilation channel (22).
