Composite sound insulation structure, sound insulation door, shutter and sound insulation wall
The invention provides a composite sound insulation structure, a sound insulation door, a blind window and a sound insulation wall. The composite sound insulation structure comprises a through hole sound absorption plate, a closed hole sound insulation plate and a resonance cavity formed between the through hole sound absorption plate and the closed hole sound insulation plate. Wherein the through hole sound absorption plate is arranged on the side close to a noise source, noise enters the resonance cavity after passing through the through hole sound absorption plate, and the strength is weakened under the action of the resonance cavity and the closed hole sound insulation plate. By means of the composite sound insulation structure and the sound insulation door, the blind window and the sound insulation wall formed by the composite sound insulation structure, the problem that noise of different frequencies is blocked in the prior art is solved, and noise pollution is reduced.
本发明提供了一种复合隔声结构及隔声门、百叶窗和隔声墙，包括通孔吸声板和闭孔隔声板以及二者之间形成的共振空腔；其中，所述通孔吸声板设在靠近噪声源的一侧，噪声经过所述通孔吸声板后进入所述共振空腔内，在所述共振空腔及所述闭孔隔声板的作用下强度减弱。利用上述复合隔声结构及其构成的隔声门、百叶窗和隔声墙，以解决现有技术中对不同频率的噪声的阻隔，减少噪声污染。
