The implementation principle of the embodiment is as follows:

when the sound wave emitted by the sound source propagates to other areas, the sound insulation wallboard 1 which can not be smoothly penetrated by the blocking sound wave is arranged on the way of the sound wave propagation, so that the sound wave generates great energy loss when passing through the sound insulation wallboard 1, and the purpose of reducing the influence of the sound of the area to be protected is achieved. This is the working principle of the middle acoustic wall panel in the present embodiment.

Specifically, the sound emitted from the sound source enters the sound insulation wall board 1 through the first through hole 151 of the second sound insulation board 15, and a part of noise converts energy into heat energy through the vibration of the glass wool; another part of the noise is resonantly absorbed by the first baffle 11 and the second baffle 15.
