Investigation on 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 or ASTM have been used for evaluating sound performance in domestic so far. In this study, every regulation from ISO, ASTM, especially for airborne sound insulation against suspended ceiling system, is analyzed in order to apply to establishment of Korean Standards on test methods and test facility of suspended ceiling system and materials.
