住宅環境の悪化を招いている。By the way, in the floor structure having such a configuration, a wood-based material is widely used especially for an apartment house or the like instead of using a conventional carpet or the like as a finishing material. However, when using this wood-based material, the impact sound when an impact is applied to the floor propagates directly to the floor base as a solid sound, compared to carpet, causing loud noise downstairs, etc.
This has led to a deterioration in the housing environment.

An experiment was conducted in which an object was dropped on the floor in accordance with A-1418, and the blocking characteristics at that time were examined. As a result, the results shown in FIG. 40 were obtained. It should be noted that I in the figure shows the light-weight impact sound cutoff characteristics of the soundproof floor structure according to the present invention, II in the figure shows the heavy-weight impact sound cutoff characteristics, and III
Indicates a light impact sound in a conventional floor structure, and IV in the figure indicates a heavy impact sound.

相関関係について次表に示す。As shown in this graph, according to the soundproof floor structure of the present invention, the floor impact sound level transmitted downstairs is, for example, 2 ranks (10 dB) for light impact sound and 1 rank (7d for heavy impact sound).
B) It has been found that good breaking performance can be obtained with respect to the impact noise of both light and heavy falling objects. Therefore, according to the soundproof floor structure of these embodiments, the floorboard vibrates due to the drag of the chair or the fall of the object, and effectively absorbs or shields the solid sound that may be radiated and propagated to the underfloor space. Thus, the sound pressure under the floor can be reduced as much as possible. Here, the following table shows the correlation between the sound insulation grade of the floor impact sound and the actual feeling of life.
