Architects designing noise sensitive buildings like recording studios, libraries and hospital wards need precise sound insulation data to select the right wall material, and standardized acoustic tests for EPS Cement Sandwich Wall Panel provide clear, reliable reference values. A 75mm thick EPS Cement Sandwich Wall Panel delivers a weighted sound reduction of 38 dB, which is sufficient for basic internal partition walls in standard residential homes. A 100mm thick EPS Cement Sandwich Wall Panel increases this value to 43 dB, meeting the sound insulation requirements for standard hotel rooms and office meeting spaces. When you upgrade to a 150mm thick EPS Cement Sandwich Wall Panel, the weighted sound reduction jumps to 51 dB, which can block most loud indoor activities and external traffic noise for quiet hospital wards and library reading areas. By adding an extra 10mm air gap between two layers of EPS Cement Sandwich Wall Panel, you can push the overall sound insulation performance even higher to meet the strict requirements of professional recording studios. All these test results are measured in official acoustic laboratories, giving designers clear, accurate performance data to select the exact EPS Cement Sandwich Wall Panel thickness for their specific project noise control needs.
