Composite board with noise reduction structure for indoor decoration

The utility model discloses a composite board with a noise reduction structure for indoor decoration, which comprises a composite sound insulation board sleeve, the left side of the inner wall of the composite sound insulation board sleeve is fixedly connected with a noise reduction and heat insulation felt, and the right side of the noise reduction and heat insulation felt layer is fixedly connected with a polyester fiber sound absorption board. And the right side of the polyester fiber acoustic board is fixedly connected with a microporous wood acoustic board, and a heat dissipation opening is formed in the right side of the composite sound insulation board sleeve. Noise is blocked by the microporous wood sound-absorbing board and the polyester fiber sound-absorbing board through the heat dissipation openings, sound energy of the noise is converted into heat energy to be dissipated, the noise is secondarily blocked and silenced by the silencing heat-insulating heat-preserving felt and the composite sound-in
