Abstract
An acoustical barrier having a central aperture that is defined by a flexible seal. The acoustical barrier has an inwardly directed flange circumscribing of the central aperture and spacing the mass layer from a wall a predetermined distance. The wall has an aperture in which is disposed a moisture seal through which a pass-through component extending from one side of the wall to another side of the wall is positioned. The pass-through component is mounted to an article that is disposed within the central aperture of the acoustical barrier. The flexible seal is positioned away from the moisture seal and blocks the transfer of acoustical noise from one side of the wall to the other.
