Abstract (en)
A wall passage provided to be incorporated in a wall of a building and configured to be connected to an air displacing unit, the wall passage comprising an air inlet and an air outlet, wherein provided between the air inlet and the air outlet is a sound trap which takes the form of a chamber with a chamber air inlet and a chamber air outlet between which at least a segment of the channel is situated, wherein the segment of the channel secondarily guides the airflow in a direction parallel to the wall and wherein the chamber is formed such that the airflow travels in the chamber through a substantially two-dimensional bend which lies parallel to the wall in order to prevent a linear airflow from the chamber air inlet to the chamber air outlet and so damp propagation of sound through the chamber.
