Sound insulation brick and sound insulation device
The invention provides a sound insulation brick, and the brick comprises a strength layer, an acoustic black hole structure layer and a sound absorption layer, wherein the strength layer is used for providing structural support; the acoustic black hole structure layer is arranged on one side of the strength layer, and an acoustic black hole structure is arranged in the acoustic black hole structure layer; the sound absorption layer is arranged on the side, away from the strength layer, of the acoustic black hole structure layer and used for absorbing part of sound. The sound insulation brick has good structural strength and sound insulation performance and is low in cost.
本申请提供一种隔声砖，该隔声砖包括强度层、声学黑洞结构层以及吸音层，强度层用于提供结构支撑；声学黑洞结构层设置在强度层的一侧，声学黑洞结构层内设置有声学黑洞结构；吸音层设置在声学黑洞结构层远离强度层的一侧，用于吸收部分声音。该隔声砖具有良好的结构强度以及隔声性能，且成本较低。
