Sound proof acoustic enclosures are specially built housings designed to reduce noise from generators, compressors or industrial machinery. Constructed with strong, corrosion‑resistant metal shells (often mild steel or CRCA) and lined inside with high‑density sound‑absorbing materials like rock wool, mineral wool or foam, they block, absorb and isolate sound. Key features include modular panels, vibration isolation mounts, acoustic louvers or ducting for intake and exhaust, weather‑proof seals and doors with gaskets. They allow necessary airflow for cooling while keeping noise down—often reducing 20‑30 dB(A) or more under free‑field conditions. Such enclosures help meet regulatory norms, protect workers, and improve the environment.
