Insulation Performance

Apartment buildings are constructed using box frame structures that integrate slabs and wall frames, and vibrations can easily travel through these integrated box frame structures. On the other hand, such a framed structure generates fewer gaps between structural elements, assuring a superior insulation performance of airborne sound compared to wooden houses. Vertically installed equipment running through different floor levels can serve as a transmission route for airborne sound of specific frequency bands. In this study, we sought to develop technical methods to improve the inter-floor airborne sound insulation performance. To this end, we measured the sound insulation performance of floor structures and intensity levels in noise penetration areas. The sound insulation performance of the living room floor structure was measured to exceed 51 dB, which was superior to that of the restroom floor by 2–7 dB. Intensity measurements identified the central and corner areas of the living room as high-level noise areas.
