ABSTRACT:
A sound damping apparatus has a resilient wall that defines a first volume and rigid walls defining a second or third volume. A gas entry communicates with the volume defined by the resilient wall. The resilient wall and the rigid walls are in contact such that gas pressure separates the walls and the wall to intermittently define a gas exit between volumes within the wall.
