Abstract

Cabinetry for a variety electronic devices that facilitates acoustic attenuation. Although significantly lighter in weight, the structural integrity of the cabinetry tends to be comparable to conventional cabinetry. The cabinetry utilizes expanded polystyrene (EPS) foam to form the basic shell or core with the shape of the desired enclosure. Appropriate coatings are then added to the surface of the EPS shell to ensure durability. The low mass, low modulus of elasticity and high internal damping of the EPS core of the completed enclosure strongly absorbs and, thus, attenuates noise emanating from within the enclosure. The addition of high density coating(s) to the faces of the EPS core provide high weight per unit area material that further blocks the passage of sound through the EPS core.
