Abstract
A panel spacer is disclosed that enhances the natural damping characteristics of the material used for construction. The spacer is shaped to redirect acoustic and vibrational energy into a direction parallel to the panel surfaces and to take advantage of the faster energy propagating through the material of the spacer relative to surrounding gasses. Energy propagating through the spacer will arrive at a mid-point of the spacer well before sound originating from the same source can reach the same point through air or another gas. The phase discrepancy between the induced displacements of the spacer and the surrounding gas is used to dissipate energy by causing the spacer to interacting viscously with the gas.
