Ceramsite composite acoustic board and sound absorption method thereof
The invention discloses a ceramsite composite acoustic board and a sound absorption method thereof, and relates to the field of sound absorption boards. The ceramsite composite acoustic board comprises a shell, a ceramsite layer and a sound insulation layer, the ceramsite layer and the sound insulation layer for noise to sequentially pass through are arranged in the shell, and a cavity is formed between the sound insulation layer and the inner wall of the shell. The cavity is formed between the sound insulation layer and the inner wall of the shell, a small part of noise enters the cavity after passing through the ceramsite layer and the sound insulation layer and repeatedly oscillates in the cavity until attenuation is zero, and the sound absorption and sound insulation effects are improved; and the ceramsite layer is arranged to replace rock wool, glass wool and other fiber materials, the structural strength is improved, the ceramsite composite acoustic board is not easy to damage and good in weather resistance, the function cannot be reduced within the service life, and solid waste pollution cannot be caused by natural degradation after scrapping.
本发明公开一种陶粒复合吸声板及其吸声方法，涉及吸声板材领域，包括：壳体、陶粒层和隔声层，在壳体内设置有供噪音依次穿过的陶粒层和隔声层，隔声层与壳体内壁之间具有空腔；本发明中隔声层与壳体内壁之间具有空腔，少部分噪音在通过陶粒层和隔声层后进入该空腔，并在该空腔内反复震荡，直到衰减为零，提高了吸声、隔音效果，而且设置陶粒层替代岩棉、玻璃棉等纤维材料，提高了结构的强度，不易破损且耐候性好，在使用年限内功能不会降低，报废后自然降解不会造成固废污染。
