    Abstract: An acoustic door system including an improved peripheral seal and a lower adjustable seal. An acoustic door swings on camming hinges which raise the door upon opening. A lower vertically adjustable U bracket has a lower neoprene sealing strip which contacts the threshold of the door frame. The peripheral seal has a portion compressed between the marginal edge of the door and frame and a portion compressed between the door panel and frame, providing acoustical sealing between the frame and two perpendicular surfaces of the door. In another form, an improved astragal gasket is compressed in the central gap between a pair of doors, the gasket also contacting an inner panel of both doors.
