There are two distinct features in Korean apartments. The first is Ondol, a floor radiant panel heating system that consists of an array of heating coils buried into a hard mortar finish. This allows residents to stand on the hard floor without shoes on. Next is a structural system composed of load bearing walls and slabs instead of beams and columns. Bare feet on hard surfaces cause severe noise from their impact with the floor. Furthermore, the tight and wide bonding between the slabs and the load bearing walls effectively transmits noise to the rooms underneath. This type of impact source cannot be simulated by a standard tapping machine, and may not be efficiently protected by usual floating floors. Four standard floor structures were introduced in the building code established in 2005 and all have 210mm thick floor slabs,. However, there are over five-million apartment units built before 2005, most of them having 135mm slabs. This study deals with a systematic approach to improve the performance of insulation used to absorb impact noise for apartments having shallow 135mm slabs. The construction between floors is investigated, specifically the following four components and their roles: Suspended ceiling and plenum (slab and its stiffness), thickness of the slab, the floor floating system, and resilient panel (for Ondol) support system.
