Evaluation of Floor Impact Sound Insulation Performance for Building Floors with Damping Materials

완충재 적용현장에서의 바닥충격음 차단성능 현황분석

Floor impact sound has caused many acoustical complaints to the apartment building dwellers. The concrete floating floor construction is one of the most reasonable way to reduce floor impact sound. Recently, many damping materials are used in apartment buildings. In this study, to evaluate floor impact sound insulation performance, field tests were carried at five building floors with damping materials. The test results of impact sound insulation performance for five buildings showed good improvement in light weight impact sound after installation of damping materials, but heavy weight impact sound wasn't improved.
