    摘要: An embeddable air duct block includes a tubular member extending between a pair of rectangular plate members spaced from each other. The tubular member has a pair of open ends and an interior passageway. One plate member has an inner surface coupled to one open end and a plurality of holes in fluid communication with the interior passageway. The other plate member is coupled to the tubular member and has a duct opening aligned with the interior passageway. Two cement cavities are preferably formed on opposite sides of the tubular member. An air duct is formed in a concrete block wall by installing and securing the air duct block in the concrete block wall. The blocks are coupled together by cementing slurry poured into the cavities. Optionally, reinforcing bars can also be utilized within the cement cavities and at least one cavity of the concrete block wall.

    摘要: An acoustic attenuator includes an intake air duct having an intake air duct opening leading to an outside environment and a blower fan opening leading to a blower fan. Air is drawn through the intake air duct opening towards the blower fan and a primary reflecting panel disposed in the intake air duct. The primary reflecting panel is configured to reflect sound propagated from the blower fan away from the intake air duct opening.

    摘要: There is provided a double-walled structure for coupling to another double-walled structure. The coupling connects one female end portion of the one structure and one male end portion of the other structure together. The connecting requires only connecting of the outer walls of the structures together, providing an overlapping connection. The inner walls of the structures have a gap between their ends, when connected. Thereby the coupling of the structures is facilitated. The space between the inner wall and outer wall of the structure is occupied by an insulating material, such as a sound absorbing fibrous batting. The space between the male/female end portions for connection to a female/male end of another structure is filled by a seal, preventing loss of insulating material and providing insulation of the joint coupling the double-walled structures together. The structure can be used, especially, as a segment in a sound-absorbing ductworks system.
