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.

Insulation Performance

The floor impact noise generated in a building often causes problems among residents. The floor impact sound insulation performance of timber construction buildings is lower than that of concrete construction. However, due to the large supply of wood and the stress-relieving effects of wood, the use of wood is being promoted around the world. In Japan, the Act on the Promotion of the Utilization of Wood in Public Buildings was enforced to promote the use of CLT (Cross Laminated Timber) for the effective use of wood. We have been experimentally investigating the effect of floor finish structure in CLT model building. In this paper, we report the measurement results of the change in floor impact sound insulation performance when the suspended ceiling structure was changed. As results, it was confirmed that the effect of the sound-absorbing material in the ceiling cavity and the effect of the double-layer ceiling board were effective. In addition, it was clarified that the dry-type double floor structure with rubber vibration insulator on its legs is an effective floor finish structure for improvement of heavy and light weight floor impact sound insulation performances.
