Sound absorption structure capable of adjusting sound field characteristics in anechoic room
The invention discloses a sound absorption structure capable of adjusting sound field characteristics in an anechoic room. The sound absorption structure comprises a basic sound absorption layer and amovable sound absorption layer, wherein the basic sound absorption layer and the movable sound absorption layer are arranged outwards in sequence along a wall body of the anechoic room, the basic sound absorption layer is fixedly installed on a wall body of the anechoic room and covers the whole wall face, the movable sound absorption layer comprises a movable bottom layer and a fixed surface layer, the fixed surface layer is composed of several fixed sound absorption blocks which are arranged at intervals, and the movable bottom layer is composed of several movable sound absorption blocks. The movable sound absorption block do not cover the whole wall face, thus a channel for the movement of the movable sound absorption blocks is formed, the movable sound absorption blocks can be combined and spliced by different movement ways, thus the thicknesses formed by the fixed sound absorption blocks and movable sound absorption blocks at different positions on the movable sound absorption layer are adjusted, and the characteristics of the sound field of the anechoic room are changed. According to the sound absorption structure, one anechoic room can correspond to multiple sound field characteristics, the site is thus saved, and the construction cost is reduced accordingly.
本发明公开了一种能调节消声室内声场特性的吸声结构，包括基础吸声层和移动吸声层，所述基础吸声层和移动吸声层沿着消声室的墙体依次向外设置，基础吸声层固定安装在消声室的墙体上且布满整个墙面，移动吸声层包括移动底层和固定表层，固定表层由间隔设置的若干固定吸声块组成，移动底层由若干块移动吸声块组成，所述移动吸声块不铺满整个墙面，从而形成供移动吸声块挪移的通道，所述移动吸声块能通过不同的挪移进行组合拼接，从而调节移动吸声层上不同位置处固定吸声块与移动吸声块组成的厚度，改变消音室的声场特性。本发明使一个消声室能对应多种声场特性，从而节约场地，节约建造成本。
