Abstract

The silencer includes sound absorbent material.
To achieve a high degree of endways silencing and to prevent the spread of sound along the axis of ducting in which the silencer is installed, the silencer includes a silencer pod (30) forming a finger of sound absorbent material at the axis of the ducting.
