매단 천장의 실간 공기전달음 차단성능 측정방법의 KS규격화 방안

Korean Standard Draft of the Laboratory Method of Measuring the Airborne Sound Insulation of a Suspended Ceiling

Offices and other multipurpose buildings commonly have suspended ceilings installed over room dividing wall. But Korean Standards don't include any code on test methods and test facility of the suspended ceiling system. Therefore, test methods and test facility from ISO and ASTM have been used for evaluating sound performance in domestic so far. In this study, Korean Standards draft on test methods and test facility of suspended ceiling system and materials is proposed on the basis of ISO and ASTM.
