Abstract

An air vent (1a) for installation in a wall (2) of a building for directing a flow of air into a room of the building, the air vent comprising:- a housing (3) defining a cavity (4), wherein a sound absorbing material is arranged within the cavity;- an air inlet tube (7) for guiding air into the cavity;- an air outlet tube (8) for guiding air out of the cavity;wherein each of a volume of the air inlet tube and a volume of the air outlet tube are smaller than a volume of the cavity, and wherein the cavity has a larger cross-sectional area than each of the air inlet tube and the air outlet tube, such that the cavity together with the air inlet tube and the air outlet tube form a reactive silencer.
