Factors affecting the performance of the sound insulation door

The way that sound waves are transmitted through the door is mainly the door leaf and the door seam. Therefore, in order to obtain a sound insulation door with high sound insulation, it is necessary to start from the above two aspects.

(1) Improve the sound insulation of the door leaf

In order to ensure that the door closure is light and flexible, it is impossible to excessively adopt a method of increasing the door leaf weighting to obtain a higher sound insulation amount:

1) Combine materials with different acoustic resistances into a multi-layer composite structure door leaf.

2) Prevent the panel's anastomosis effect from appearing in the effective frequency range to reduce the sound insulation.

(2) Improve the sealing measures of the door joints

1) The influence of the door gap on the sound insulation is the change of the sound insulation when different door seal methods are used on the same door.

2) Method of sealing the door seam

a, early "9" shaped rubber seal

b. Adopt double channel sealing strip measures.

c, the noise reduction effect of the door silencer
