Abstract
An acoustic system includes a housing includes an acoustic element opening with an inner edge extending from a first, outer surface of the housing to a second, inner surface of the housing, and an acoustic element having an acoustic element foam layer extending at least partially along a circumferential perimeter of the acoustic element, where the acoustic element foam layer is configured to engage the inner edge of the acoustic element opening when the acoustic element is positioned within the opening, and where the acoustic element foam layer is compressed in a direction perpendicular to a central axis of the acoustic element when the acoustic element is positioned within the opening, such that an acoustic seal is created.
