Low-frequency sound absorption structure and sound absorption method thereof
The low-frequency sound absorption structure is technically characterized in that the low-frequency sound absorption structure comprises a tip tower and a base of the tip tower, the periphery and the top of the base are closed, the bottom of the base is open, a base cover plate is arranged on the top of the base, dense sound transmission holes are formed in the surface of the base cover plate, each sound transmission hole is in a short tube shape, and the bottom of each sound transmission hole is open. The bottom of the sound transmission hole is located in the base, sealed small elastic bubbles are bonded to the lower end of the sound transmission hole, a certain gap is reserved between every two small elastic bubbles, and sound absorption fibers are laid at the bottom of the base. High-frequency sound waves in sound waves are absorbed through the tip tower, low-frequency sound waves are absorbed through the elastic small balls in the base and the sound absorption fibers at the bottom, the effect of absorbing the low-frequency sound waves is achieved on the whole, by means of the mode that external noise is absorbed in different frequency bands, the function that the sound absorption structure absorbs the low-frequency sound waves below 100 Hz can be achieved without increasing the size, and the sound absorption effect is good. The method can be widely applied to construction of anechoic rooms.
本发明涉及一种低频吸声结构及其吸声方法,其技术特点是：该低频吸声结构包括尖塔及其基座，所述基座为周侧及顶部封闭、底部开放结构，在基座顶部设有基座盖板，在基座盖板表面制有密集的透声孔，每个透声孔均为短管状，该透声孔底部位于基座的内部，在透声孔的下端粘接有密封的弹性小泡，每个弹性小泡之间留有一定的空隙，在基座底部铺设有吸声纤维。本发明通过尖塔吸收声波中的高频声波，通过基座内的弹性小球及底部吸声纤维吸收低频声，从整体上达到了吸收低频声波的效果，这种将外界噪声分频段吸收方式，实现了不增加尺寸能够实现吸声结构对100Hz以下低频声波吸声功能，可广泛用于消声室的建设中。
