If effective noise reduction measures are not taken, the noise of the generator set will cause serious harm to the lives of surrounding residents. In order to protect and improve the quality of the environment, the noise of the generator set must be prevented. Traditional silencer doors usually use sound insulation materials or multi-layer structure design to achieve the effect of silencer.

[0003] In the prior art, a Chinese patent document with publication number CN109162606A is proposed to solve the above technical problems. The technical solution disclosed in the patent document is as follows: a soundproof door, comprising a door frame and a door leaf located inside the door frame, a fire-proof expansion sealing strip is arranged between the door leaf and the door frame, one end of the door leaf is hinged to the door frame, and the other end is connected to the door frame through a door lock.

However, this kind of sound-absorbing door is relatively complex in structure and has high production cost. In addition, in actual use, due to the heavy weight of the door leaf, it is not convenient to operate. Therefore, it is necessary to design a new type of sound-absorbing door that can achieve good sound-absorbing effect and has the advantages of simple structure, low production cost and convenient operation.
