| 요약2 | In the present study, floor impact sound reductions by floor structure and ceiling were investigated. Upper layer of a dry double floating floor was made of recycled materials. Also, steel as well wooden beams were applied to the dry double floating floor then impact sound insulations of them were measured. It was found that light-weight impact sound insulation of the floor with steel beam was improved by 4 dB (L'n,AW) compared to the floor with wooden beam. Moreover, heavy-weight impact sound insulations of the floor with steel beam were enhanced by 3 dB and 4 dB (L'i,Fmax,AW), respectively using bang machine and rubber ball. As a second experiment, the impacts of ceiling aperture on the floor impact sounds were measured while the steel beams were installed to the dry double floating floor. The light-weight impact sound insulation was found to be best, 32 dB when apertures were applied to perimeters of coffered ceiling. The heavy-weight impact sound insulation measured by the bang machine was 48 dB when the apertures were installed to moldings. In contrast, two experimental cases without any aperture and apertures on perimeters of the coffered ceiling showed best heavy-weight impact sound insulations of the rubber ball (40 dB). Lastly, influences of impact positions on single number ratings were investigated. It was observed that there was not a significant relationship between impact positions and single number ratings. |
