Conventionally, this type of soundproof room has a structure in which anti-vibration material is laid only between the floor of the building frame and the floor of the soundproof room, and the wall is directly installed on the floor, and noise propagates downstairs from the wall And it was difficult to obtain a high soundproof performance.

That is, as shown in FIG. 13, a vibration isolator 53 is laid on a floor 52 of a living space 51 formed by partitioning into a building frame 50 of a reinforced concrete structure, and a floor material of a soundproof room is placed thereon. 54 (floor panel) is placed. The wall panel 56
It stands and stands directly on the frame floor 52, and a ceiling panel 57 is erected on the wall panel 56. In the conventional structure described above, sound radiated from a sound source such as a musical instrument is incident on a wall panel and a ceiling panel, and this sound propagates as solid sound from the wall panel 56 to the floor slab (the skeleton floor 52) or the skeleton wall. Propagating to the building structure such as floor slabs and walls in the upper and lower floors and adjacent rooms, and radiating from the structure into the living space (solid sound propagation) Could not.

Therefore, as a structure for improving the sound insulation performance, a soundproof room structure as shown in FIG. 14 has been conventionally put to practical use. The figure is a diagram schematically shown. As shown in FIG. 14 (a), vibration insulators 53 (... represent a plurality of members; the same applies hereinafter) are laid on a frame floor 52 of a living space 51 formed by partitioning into a building frame 50 having a reinforced concrete structure.

As already mentioned, by playing the piano,
Sound is incident on the wall panel 2, the ceiling panel 3, and the floor panel 4 as a sound source, and the incident sound is solid sound from the wall panel 2, the ceiling panel 3, and the floor panel 4 to the wall of the building frame 50,
It is transmitted to the ceiling and floor slabs (frame floor), then propagates to the floor, slabs, walls, etc. in the upper and lower floors and adjacent rooms, and radiates from the skeleton to the room. It was difficult. In the present invention, first, the sound incident on the wall panel 2 and the ceiling panel 3 is transmitted from the wall to the skeleton floor 52 because the wall panel 2 is installed and supported on the skeleton floor 52 via the vibration isolating material 11.

Suppressed and attenuated. Floor panel 4 indicated by arrow
Since the floor panel 4 has a vibration isolating structure, the transmission of the air noise to the skeleton floor 52 is suppressed and attenuated as much as possible. In addition, since a sealing material is interposed at the joint between the wall panel 2, the ceiling panel 3, and the floor panel 4, it is possible to prevent sound from leaking from this part. Thus, the sound insulation performance of the soundproof room 1 is improved as a whole.

By the way, the vibration-proof rubber of the present invention is 1-20
Hz, preferably a natural frequency of about 15 Hz. The reason for this is to use a vibration-proof rubber having a natural frequency of about 15 Hz in consideration of the rigidity of the vibration-proof rubber and the audible frequency. In the above-described embodiment, an example in which rubber is used as the vibration damping material is described. However, glass wool, a structured spring, or the like can be used as the vibration damping material. This is the same in the following embodiments.

The present inventors measured and compared the sound insulation performance of the conventional soundproof room and the soundproof room according to the present invention. The measurement results are shown in the graph of FIG. In the graph, the horizontal axis indicates the octave band center frequency (Hz), and the vertical axis indicates the sound pressure level difference (dB). The results of measurement of the radiated sound outdoors in the case of no wall panel vibration isolation support are indicated by ●-●, the results of the solid-borne sound measurement in the downstairs of the structure of the present invention (wall panel vibration isolation support) are indicated by □-□, and those of the conventional structure (wall panel vibration isolation support). ★-★
