Acoustic Treatment Detail Drawing for Walls Ceiling and Metal Roof

This AutoCAD DWG file presents a comprehensive acoustic treatment schematic detailing sound insulation solutions for interior walls, ceilings, floors, and metal roof systems. The drawing includes multiple sections, such as acoustic insulation over metal roofing with sprayed cellulose insulation layers of 2 inches and 4 inches thickness, combined with gypsum boards, and slab concrete interfaces. Wall buildup details illustrate Hebel walls of 100 millimeters and 210 millimeter thickness with smooth plaster finish, wood or hollow studs, perforated plywood panels, acoustic backing insulation, and double-layered 12 millimeter gypsum boards. Specialized acoustic wall assemblies are shown for main halls, training rooms, media rooms, VIP waiting areas, and inter box partitions, with NRC values around 0.7 to 0.9, and STC ratings indicated for performance reference. Floor buildup details include carpet finishes, acoustic pads, and slab connections for noise reduction. This acoustic treatment working drawing is suitable for architects, MEP consultants, designers, and engineers involved in auditorium, studio, training hall, and commercial sound control projects using AutoCAD DWG files, and can be coordinated with CAD drawings for integrated site and boundary detailing in architectural projects.
