| 요약2 | The purpose of this study was to satisfy the extent to which the impact sound was reduced when the actual impact force (sound) was applied to the floor mats in various floor structures of apartment houses and that the impact sound was reduced in each of the 125 Hz and 250 Hz bands. It is an evaluation of whether you did it. It was found that PE floor mats have higher impact sound reduction performance than PU floor mats when actual impact force (rubber hole drop height 40 cm) from the upper part of the wet floor structure of apartment houses. In terms of single number quantities, a maximum impact sound reduction performance of 5 dB was found. Even in the semi-dry floor structure, it was found that PE floor mats secured a maximum of 3 dB of actual impact sound reduction performance. In the double-floor structure, the impact sound reduction performance was found to secure a maximum of 2 dB. As a result of evaluating the perception range (3 dB) after installing floor mats in the wet and semi-dry floor structures, it was found that when installing more than 20 mm of PE material, the residents have a range of 3 dB that can be perceived as ‘the impact sound has been reduced’. Overall, floor mats made of PE were found to have somewhat better performance than floor mats made of PU. In the case of floor mats (Case 11 ~ Case 18) combining various materials, it was found that the impact sound reduction performance recognition range of 3 dB was not secured in the upper part of the double floor structure. |
