Acoustic Wall Section Detail AutoCAD DWG with Hollow Cavity Design

This acoustic wall section detail AutoCAD DWG file presents a comprehensive construction drawing designed for sound insulation and interior room separation. The layout illustrates a Type A acoustic wall configuration with a hollow cavity of approximately 50 mm to 75 mm between two parallel wall panels for noise reduction. The drawing includes gypsum board layers of nearly 12 mm thickness, metal stud framing of about 50 mm width, and high-density insulation infill for improved sound absorption. Final finishing layers, plaster thickness, and surface treatment details are clearly marked for accurate execution. Sectional hatching, dimension lines, and standardized construction symbols ensure clarity for architectural and site use. This wall section detail supports professional acoustic planning and interior detailing. The file also features plan and sectional views explaining room partition alignment, joint sealing methods, and wall-to-slab connection details. Fixing screw spacing, edge profile treatment, and finishing skirting details are illustrated for durability and aesthetics.
