The invention discloses a wooden sound-absorbing plate. The wooden sound-absorbing plate comprises a supporting plate and a plurality of plate frames. Supporting blocks are fixedly arranged on the oneends of the plate frames, one end of the plate frame is hinged to the one end of the adjacent plate frame, and one side, far away from the plate frames, of the supporting plate is provided with a plurality of expansion bolts; a first
airbag is arranged between the two supporting blocks at the same hinged junction, and a second
airbag is arranged between two supporting blocks at the different hinged junctions; an
air pump is arranged on the supporting plate, and the
air pump is in communication with the first
airbag and the second airbag; inner frames are arranged on the plate frames, the inner frames are provided with a plurality of cross bars, the cross bars are connected with
noise reduction plates in a rotated mode, and pull ropes for controlling the turning of the
noise reduction plates are embedded in the cross bars; and each
noise reduction plate comprises a first decorative layer, a sound
insulation layer, a silencing layer, a sound-absorbing layer and a second decorative layerwhich are sequentially bonded, wherein the silencing layer includes a plurality of silencing holes, and the silencing layer includes a plurality of silencing balls. Compared with the prior art, the wooden sound-absorbing plate can effectively deal with the noise, so that the noise effect can be effectively reduced, and at the same time, the wooden sound-absorbing plate is convenient to install and disassemble and capable of being used according to the need.
