Noise reduction sound insulation board
The invention discloses a noise reduction sound insulation board which comprises a noise reduction cotton layer, sound absorption boards are bonded to the two sides of the noise reduction cotton layer, a sponge sound insulation layer is bonded to the outer side of each sound absorption board, a sound insulation board is bonded to the outer side of each sponge sound insulation layer, and the two sound insulation boards are made of different materials. The sound insulation board has multiple sound insulation materials, and the elastic damping layer is arranged in the sound insulation board, so that the noise reduction effect of the sound insulation board can be effectively improved.
本发明公开了一种降噪隔声板，包括消音棉层，消音棉层的两侧均粘接有吸声板，每一吸声板的外侧均粘接有海绵隔音层，每一海绵隔音层的外侧均粘接有隔声板，两块隔声板采用不同材质。本发明具有多种隔声材质，并且内部设置弹性阻尼层，可有效提高隔声板的降噪效果。
