本发明公开了一种模块式隔音墙板，包括外墙板，所述外墙板的一侧定连接有左墙板，所述外墙板的另一侧固定连接有右墙板，所述外墙板的顶端与底端均固定连接有底板，所述底板的后表面固定连接有后墙板，所述底板的上表面固定连接有蜂巢吸音板，所述底板的上表面固定连接有第一隔板，所述底板的上表面固定连接有第二隔板，所述第二隔板的前表面均匀开设有九个滑槽；蜂巢吸音层可将大分贝的噪声吸收，将振动转换为其芯材的的变形能，引起空气与材料的震动，由于摩擦力与粘滞阻力，使得噪声的部分声能转换为热能，既能降低分贝，又能稳固噪声频率频段；经过稳固的噪声频段，超声波会被超声波吸音板吸收，次声波会被次声波吸音板吸收。

The invention discloses a modular sound insulation wallboard. The wallboard comprises an outer wallboard body, a left wallboard body is fixedly connected to one side of the outer wallboard body, a right wallboard body is fixedly connected to the other side of the outer wallboard body, bottom plates are fixedly connected to the top end and the bottom end of the outer wallboard body, and a rear wallboard body is fixedly connected to the rear surfaces of the bottom plates. Honeycomb sound absorption plates are fixedly connected to the upper surfaces of the bottom plates, first partition plates are fixedly connected to the upper surfaces of the bottom plates, second partition plates are fixedly connected to the upper surfaces of the bottom plates, and nine sliding grooves are uniformly formedat the front surfaces of the second partition plates; a honeycomb sound absorption layer can absorb large-decibel noise and convert vibration into deformation energy of a core material of the honeycomb sound absorption layer to cause vibration of air and materials, and due to friction force and viscous resistance, part of sound energy of the noise is converted into heat energy, decibel can be reduced, and the noise frequency band can be stabilized; and through the stabilized noise frequency band, ultrasonic waves can be absorbed by an ultrasonic sound absorption plate, and infrasonic waves canbe absorbed by an infrasonic wave sound absorption plate.
