As a further aspect of the present invention: and plastering layers are arranged on the outer sides of the walls, and the thickness of each plastering layer is 25-35 mm. Get rid of the hole and the gap of wall through the layer of plastering, reduce hole and gap to syllable-dividing adverse effect.

As a further aspect of the present invention: the front side and the rear side of the wall body are connected and sealed with other wall bodies.

As a further aspect of the present invention: a gap is arranged between the soundproof cotton and the fiber cement board.

Compared with the prior art, the beneficial effects of the utility model are that:

through the design, have the acoustic celotex board for sound has reduced the acoustic energy and has reduced the volume after the collision that receives the acoustic celotex board after passing the wall body, and adopts multiple sound insulation material to give sound insulation, avoids appearing the phenomenon of coincide, prevents that the syllable-dividing effect from reducing.
