SOUNDPROOF DOOR AND INSTALLATION METHOD THEREOF
PROBLEM TO BE SOLVED: To provide a soundproof door capable of exerting a performance equal to an ideal soundproof performance which is a combined soundproof performance of each soundproof door in a dual layer door comprising two soundproof doors installed at predetermined intervals and of achieving full effect of the soundproof doors invested, and an installation method thereof.SOLUTION: The invention comprises two soundproof doors with different stiffness so as not to coincide primary natural frequencies of the doors arranged side by side at intervals, and the interval of the doors is coincided with an anti-resonance frequency of space between the doors decided with a primary natural frequency of the door inside a pit.SELECTED DRAWING: Figure 1
【課題】所定の間隔をあけて２基設置した防音扉である２層式扉において、個々の防音扉の遮音性能を加算した理想的な遮音性能に匹敵する性能発揮ができるようになり、投資した防音扉の効果が十分に得られる防音扉およびその設置方法を提供する。【解決手段】間隔を存して並べる扉の１次固有周波数を一致させないように異なる剛性とした２基の防音扉からなり、扉間隔は坑内側扉の１次固有周波数で決まる扉間空間の反共鳴周波数に合わせた。【選択図】 図１
