In the present study, the characteristics of the floor impact sound for each floor structure process is analyzed. To this end, a floor structure using the resilient material expanded polystyrene (EPS) has been constructed. In addition, the thickness of the finishing materials is 7.5mm. To analyze the floor impact sound characteristics based on the floor construction process, measurements were carried out in order of (1) bare slab, (2) floating floor structure, and (3) floor coverings. A lightweight floor impact sound was confirmed to be reduced by a maximum of 23dB owing to the use of resilient materials. A heavyweight floor impact sound is the main factor in the floor impact sound performance of a bare slab. Resilient materials may increase the heavyweight impact sound pressure level at 63Hz. Therefore, it is necessary to use resilient materials that can measure the resonant frequency of the slab and thus avoid the resonant frequency of a bare slab. The results of this study are intended to be used as basic data for securing the performance of a floor impact sound insulation. |
