Abstract

In this study analyzed the factors affecting the performance of floor impact sound in the Republic of Korea apartment house. In addition, the performance of Heavy-weight impact sound and Light-weight impact sound was analyzed according to the supply area among the analysis factors. Among the approximately 628 households surveyed, the ratio of 37 to 74 m2 was the highest at 40%. More than 99% of the architectural styles are wall structures apartments. In addition, the composition ratio of the type of room (living room and room) arranged in the front was high at about 44% in 4 Bays. Wooden flooring was found to be about 81% of the type of flooring installed on the finish mortar. In addition, in the case of the receive room ceiling structure, it was found that the well type sealing system was installed at a rate of about 75%. Among the analyzed apartment building elements, this paper examined the performance of reducing heavy-weight impact sound according to the supply area. As a result, depending on the supply area, the average single-number quality (SNQ) value was less than 50 dB, but many households exceeded the minimum standard of 50 dB. In the case of light-weight impact sound, it was found that most of the minimum standard 58 dB was met regardless of the supply area.
