ABSTRACT:
An acoustic panel having at least two compressible, flexible, acoustic foam damping layers separated by at least two rigid layers. In one preferred embodiment, a first rigid layer has a second flexible foam layer spray applied, with a further spray application of a rigid third layer, followed by a spray application of a flexible foam fourth layer, followed by a spray application of a rigid fifth layer, followed by a spray application of a sixth flexible foam layer, finally followed by a spray application of a rigid seventh layer. Sound transmission through this embodiment is especially well attenuated at high audio frequencies.
