Abstract (en)
[origin: WO9733051A1] A sound deadening panel (2) for attachment to a wall, floor or ceiling structure is of variable thickness over its area to provide acoustic insulation characteristics essentially by sound reflection rather than by absorption. The panel (2) is planar on its exposed surface so as to be available for decoration but on its rear surface is profiled due to the variation in thickness. The profiling may be continuous or in discrete steps.
