The purpose of this study is to clarify the tendency to the reduction of heavy-weight floor impact sound of the floating floor by difference of the section specifications change. The floating floors were constructed in a box frame-type reinforced concrete construction which regulated in JIS A 1440-2, the reduction of transmitted heavy-weight floor impact sound levels were measured. From above results, the relationship between the section specification and the performances of them was examined. Moreover, the correspondence of two heavy/soft impact sources, a car-tire source and a rubber ball source, was investigated.
