A soundproof building structure includes a first structure including a first floor, a first wall, and a first ceiling, each of which is concrete, a second structure inside the first structure and including a second floor having a vibration isolation structure on the first floor, a steel frame structure standing on the second floor apart from the first wall below the first ceiling, a second wall including a sound insulation board on an interior side of the frame structure, and a second ceiling including a sound insulation board on the interior side, and a third structure inside the second structure and including a detachable flat panel on an interior side of the second wall. An upper end of the panel fits into a rail fixed to a ceiling member of the frame structure, and a lower end of the panel fits into a rail fixed to the second floor.

An infill wall support clip is described. The infill wall support clip provides lateral bracing for wall panels in residential or commercial buildings. The infill wall support clip anchors to a top track of wall panels and to a bottom track of a floor truss. The infill wall support clip provides spacing between the wall panel and the floor truss such that drywall may be continuously overlaid on top of the wall panel.

A composite acoustic damping batten suitable for interposition between first and second building elements, the composite acoustic damping batten comprising at least two resilient portions, each resilient portion comprising a first face and a second face, the first and second resilient portions of the at least two resilient portions being conjoined such that the first face of the first resilient portion and second face of the second resilient portion are spaced apart from each other forming opposing external surfaces of the composite acoustic damping batten; wherein the first face of the first resilient portion is configured for securable contacting engagement with the first building material; and the second face of the second resilient portion is configured for securable contacting engagement with the second building material.

A structural connector is provided that limits transmissions of vibrations between connected structural elements in a building or structure. The structural connector is formed from two opposing sheets with a vibration damping material connecting the two.

A modular pod includes a door, walls, and a ceiling, with the walls containing an insulation product for acoustic insulation. The exterior surface of the walls can be covered in a recycled non-woven felt material. A ventilation system is provided, including a ventilation plinth located at the base of at least one wall inside the pod and at least one exhaust fan in the ceiling for exhausting air out of the pod. The ventilation plinth is an elongated channel with openings on both the exterior and interior sides of the pod. The interior walls of the channel of the ventilation plinth are lined with an acoustic dampener to minimize the entry of noise through the air inlet of the ventilation. The pod's construction allows for assembly entirely from the interior, allowing it to be installed against a wall or in a corner.
