Acoustic Treatment Wall And Ceiling Section Detail With Material Layer

This AutoCAD DWG drawing presents comprehensive acoustic treatment details for walls, ceilings, and floors used in performance, media, and training spaces. The drawing includes multiple sectional details illustrating acoustic insulation build-ups with clearly defined material layers and thicknesses. Ceiling details show metal roof insulation using 2 x 12 mm gypsum board combined with sprayed cell acoustic insulation of 2-inch and 4-inch thickness, ensuring effective sound absorption and control. Wall sections demonstrate Hebel wall constructions of 100 mm and 210 mm thickness finished with 20 mm smooth plaster, supported by wood or hollow stud framing. Acoustic layers include perforated plywood panels, sprayed cell insulation of 2-inch thickness, gypsum boards in double layers of 12 mm, and acoustic ceiling treatments with NRC values around 0.7. All assemblies are shown with slab connections and finished floor references for accurate coordination.

Additional details cover specialized acoustic wall systems for main halls, training rooms, media rooms, and VIP waiting areas. These sections include carpet flooring with NRC 0.8, sponge pad layers of 20 mm thickness covered with fabric, rockwool insulation of 2-inch thickness, and perforated plywood with specified opening diameters and spacing. Floor and slab details are consistently marked to explain load-bearing and acoustic separation. Each detail is clearly labeled and scaled for technical clarity, supporting proper interpretation during execution. This acoustic treatment drawing is suitable for architects, civil engineers, interior designers, and MEP consultants requiring precise acoustic construction details with material specifications and measured layering for sound control design.
