Which ceiling type is primarily used for sound absorption?

• A. Exposed Timber Structure
• B. Gypsum Wallboard Ceilings
• C. Acoustical Tile/Panel
• D. Tin

Answer: (C)

Sound absorption comes from porous, open-cell materials that convert sound energy into heat as it travels through them. Acoustical tile or panel ceilings are built with fibrous, porous cores (like mineral fiber or fiberglass) and often perforated faces, which maximize absorption and reduce reverberation in a room, improving speech clarity. In contrast, exposed timber structures are dense and tend to reflect and scatter sound rather than absorb it, gypsum wallboard ceilings are rigid and reflective unless augmented with absorptive treatments, and tin ceilings are metal that mainly reflects sound. So the acoustical tile/panel ceiling is the option designed to absorb sound.
