A large number of professional acoustic performance tests have proved that EPS Cement Sandwich Panel partition wall has very reliable noise reduction effect that meets the requirements of most building scenarios. The standard 100mm thick EPS Cement Sandwich Panel can reach a weighted sound insulation value of more than 42 decibels which can completely block the daily speech noise and common household appliance noise between two adjacent rooms. If you add a layer of sound insulation felt on the surface of EPS Cement Sandwich Panel before decoration the sound insulation value can be further increased to more than 50 decibels to meet the higher noise reduction requirements of recording studios and quiet offices. The internal closed pore structure of EPS particles inside EPS Cement Sandwich Panel forms countless tiny sound wave reflection paths that consume the energy of passing sound waves effectively. Many independent third party building material testing institutions have issued formal test reports to confirm the stable and consistent sound insulation performance of qualified EPS Cement Sandwich Panel products. This verified noise reduction performance makes EPS Cement Sandwich Panel a trusted partition material for all kinds of noise sensitive building projects.
