A slip over, sound muffling cover for a machine such as a compressor is disclosed which includes an outer layer of relatively rigid, bendable, resilient material capable of being distorted and returned to its desired shape, and an inner layer of flexible, sound absorbent material. The outer layer includes a cap having a broad surface and a pair of open sided trays attached on corresponding ends thereof to the broad surface so that, under normal circumstances, the open sides of the trays face one another. Each of the trays contains a pair of elongated flanges on opposite side edges thereof, pairs of such flanges which oppose one another on the same side of the trays are closable against one another to enclose a machine in the sound absorbent material. The trays may be semi-cylindrically shaped wherein when closed against one another, they form a cylindrically shaped enclosure about a similarly shaped compressor with the cap closing one end of the enclosure over the top of the machine, and with the lower end of the enclosure being open. Preferably, the outer layer is constructed of molded, closed cell polyethelene and the inner layer is constructed of spun fiberglass and/or plastic foam.

A sound attenuating cover for a machine such as a compressor, said cover comprising an outer layer of relatively rigid, bendable, resilient material including a cap having a relatively broad surface adapted to fit over an upper surface of a machine, a pair of open sided trays attached on corresponding ends thereof to said broad surface such that the open sides of said trays normally oppose one another, a pair of elongated, outwardly projecting flanges attached along opposite side edges of each of said trays, pairs of said flanges which are located on corresponding sides of said trays being closable against one another to form an enclosure about said machine, said enclosure being bounded by said trays, being closed on one end by said cap and being open on the other end, an inner layer of flexible, sound absorbent material attached to said outer layer and covering the interior surfaces of said enclosure, and means for securing opposing ones of said flanges together for maintaining said enclosure closed about said machine.
