Abstract
An acoustical panel for use in sound reduction in connection with air compressors and similar equipment includes two oppositely disposed layers of synthetic film material which in the preferred embodiment is polyvinychloride and an intermediate layer of acoustical insulation material disposed between the two outer layers wherein the preferred material for the intermediate layer is fiberglass. The acoustical panel is made in one embodiment by adhesively bonding the first outer layer of synthetic film material to one side of the intermediate layer and then adhesively bonding the other outer layer of synthetic film material to the opposite side of the intermediate layer. Once the adhesive bonding is completed, the outer peripheral edges of each outer panel are placed in abutment and heat-sealed so as to encase the intermediate layer. The encasement in layers of synthetic film material prevents any moisture absorption by the intermediate layer and the encasement further prevents any reduction in the fibrous content of the intermediate layer due to air flow pressure.
