Conflicts from the noise between the upper and lower households are increasing in apartment houses. As recent ultra high tower-type apartment houses are constructed with 40 or more floors, the floor impact sound through a structure needs to be examined for the ultra high tower-type apartment houses. Accordingly, this study measured and analyzed the floor impact sound for the wall column structure and rahmen structure in the ultra high tower-type apartment house to understand the characteristics of the floor impact sound. From the measurement of light weight impact sound level in the apartment houses studied, a B apartment house satisfied the standard light weight impact sound level 58dB, but an A apartment house exceeded it. As for the heavy weight floor impact sound, both A and B satisfied the standard heavy weight impact sound level 50dB. As a result of analyzing the floor impact sound level by the thickness of floor slab, the B apartment house (slab thickness: 180mm) was 5～7dB lower in the light weight impact sound level and 0～3dB lower in the heavy weight impact sound level, than the A apartment house (slab thickness: 150mm). As a result of analyzing the characteristics of floor impact sound level in the wall column structure of the B apartment house and the rahmen structure of the C apartment house, both with the same slab thickness of 180mm, the C apartment house with the rahmen structure was better than the B apartment house with the wall column structure, in blocking the floor impact sound
