ABSTRACT:
Noise reduction enclosure for enclosing a sound-producing machine, including interconnected upstanding side walls and a ceiling at the upper ends of the side walls, wherein the side walls and ceiling are constructed of beams and support members having sheet metal panels floatingly mounted thereon. Resilient sealing members are mounted on the periphery of the sheet metal panels to isolate the panels from the beams and support members and to prevent noise leaks. Resilient grommets coact with fasteners to isolate the fasteners from the panels and to fix spacing between the panels and beams or support members, thus controlling proper compression of resilient sealing members. Openings are provided in the side walls of the panels and doors coact with the openings to provide access to the machine. The doors and doorways are arranged such that about ninety percent of the machine is available for servicing when the doors are in open position. Resilient sealing members are provided around the periphery of the doors to prevent noise leaks. Vibration absorbing means isolates the beams and support members from the floor.
