Abstract

A housing containing sound- deadening material 3 bounding an expansion region 5 has an inlet 2 at one end and an outlet at the other end and at least one passage 4 extends longitudinally through the sound- deadening material to connect the expansion region 5 to the outlet. The end of the, or each, passage 4 is offset with respect to the, or each, inlet aperture. <IMAGE>
