Description
【発明の詳細な説明】 〔産業上の利用分野〕 本発明は遮音パネルに関する。[Detailed description of the invention] [Industrial application field] The present invention relates to sound insulation panels.

を配設したものが知られている。Conventionally, as a sound insulating panel for preventing sound leakage to the outside from a listening room or musical instrument practice room, two pieces of plasterboard 5 shown in FIG. 4 were integrated by creating an air layer between the plasterboards using a wooden frame 6. Glass wool 7 is placed in the air layer of the hollow panel.
It is known that the

のパネルが一般的である。The size of the panel is 2900011 in width and 180 in height.
Panels with a length of 0M to 2400m and a thickness of 50 to 1501 are common.
上記遮音パネルは空気層にグラスウールを配設しないも

上する。The sound insulation performance of the above-mentioned sound insulation panel is improved by the sound absorption effect of the glass wool compared to a sound insulation panel in which glass wool is not provided in the air layer.

点があった。The conventional type mentioned above has two gypsum boards integrated with an air layer between them, and glass wool is placed in the air layer. It has the advantage that the sound insulation performance can be improved by the same amount as the effect, but as shown in Figure 3, the frequency characteristics of the sound absorption coefficient by the reverberation room method of glass wool gradually decreases in the low frequency range below 500 (Hz), so the sound insulation is not effective. There was a drawback that the amount of performance improvement was also small.
本発明は上記事由を鑑みてなされたものであり、その目
的とするところは、低音域においても大きな遮音性能を

以下、本発明の一実施例を第１図乃至第３図に基ずいて
説明する。According to the present invention, with the above configuration, the sound absorbing material made of a polymeric foam and mixed with flakes absorbs sound and improves sound insulation performance (Example) Hereinafter, one embodiment of the present invention will be described. An example will be explained based on FIGS. 1 to 3.

The air layer of a hollow panel is made by integrating two gypsum boards 5 of 2 m+ with an air layer of 25 am provided between the gypsum boards 5 using a wooden frame 6, and an average aspect ratio of about 90 for 100 parts by weight of urethane resin. Average particle size 1.4 mica 10
A sound-absorbing material with a thickness of 25 mm made by foaming 8 times the foam containing 0 parts by weight is installed, and the panel dimensions are 900 mm x
It is 1800mm x 5 Q Bl. Mica is mixed in as flakes.

The mica 3 protrudes into the pores (bubbles) 4 of the urethane resin 2, and the pores 4 have a complicated shape, making it easier to absorb the energy of the sound waves propagating inside the pores 4. In addition, hole 4
Since the mica 3 protruding inward is vibrated by sound waves, the sound energy is converted into vibration energy, which is further absorbed by the internal resistance of the mica 3 and the resistance of the urethane resin 2 and consumed as thermal energy, increasing the sound absorption effect.
