Abstract: A noise reduction door related to a noise reduction device in order to resolve a problem that the noise reduction door cannot meet a requirement for different noise reduction effects and different air duct resistance. The noise reduction door includes a T-shaped mechanical part, two fan-shaped mechanical parts, and a door plate. The T-shaped mechanical part and the fan-shaped mechanical part are connected to the door plate using a detachable connection mechanical part. The T-shaped mechanical part is located on a central axis of the door plate, and the two fan-shaped mechanical parts are respectively located on two sides of the T-shaped mechanical part. Therefore, the fan-shaped mechanical part on the door plate may be changed to have different installation positions and installation manners in order to obtain noise reduction doors in different forms. The embodiments of the present disclosure are applied in cabinet noise reduction.
