Tips for selecting soundproof doors

Nowadays, in order to avoid the impact of noise on people's health and create a green indoor acoustic environment, it is necessary to do a good job in home sound insulation and decoration. Therefore, the purchase of sound insulation doors is a step in sound insulation and decoration.

1. Watch the door panel

The door partition is not soundproof, and the main watchboard is not soundproof. The sound insulation effect of the door panel mainly depends on the filler of the door core. Generally speaking, the molded sound insulation door is filled with paper base with honeycomb structure. The closed air layer formed can play a very good role in sound insulation, and this door can achieve a sound insulation effect of 29 decibels.

2. Sound insulation and light weight

The ideal soundproof door should also have the characteristics of light weight. Can we use a 4cm thick steel plate as the door panel, or pour cement into the door panel to achieve a higher soundproof effect? Although the sound insulation effect has been achieved, the weight of the door panel has increased. The hinges and hinges of the door cannot be opened and closed easily because of the heavy load, which will affect the use function.

3. The pattern on the door panel can absorb sound

In addition to the sound insulation function, the sound insulation door of Xuanyuan Gate should also have a certain sound absorption effect. Careful people will find that most door panels have simple or complex patterns on both sides. These patterns can absorb sound and prevent sound reflection, because if the door panel is very smooth, the sound wave in the room will be completely reflected back by the door panel, forming noise.

Note: In fact, the sound insulation of doors and windows is graded like that of fire doors, rather than defined by a single item. With regard to the concepts of "sound insulation" and "sound absorption", the principle of sound insulation depends on the quality or the density of materials (when the overall weight of iron plate doors is less than that of wooden doors in a unit area, its sound insulation is inferior to that of wooden doors), Sound absorption depends on the fine surface area and uneven surface space of the material (rock wool, mineral wool, and foam are sound absorption materials rather than sound insulation materials).

In addition, in order to avoid noise, in addition to fireproof doors and sound insulation doors, there are several common sense of sound insulation and noise reduction that must be known. For example, do not buy houses facing the street, choose residential areas with green belts, and use sound insulation glass to sound insulation.

The above are the three tips for selecting sound insulation doors. Xiao Bian believes that with these three tips, you can definitely select high-quality sound insulation doors.
