Every door can play a certain role in sound insulation, but there is a big difference in the sound insulation effect.
The sound insulation effect of the door panel depends on the filler of the door core. Generally, the inner core of the molded sound insulation door is filled with paper base of honeycomb structure, because the arrangement of honeycomb can make a certain material achieve area and strength, thus increasing the strength of the door panel.
The closed air layer formed by it can play the role of sound insulation, and the door made by this method can achieve the sound insulation effect of 29 dB. Poor quality door, just in the hollow with cardboard rough to make a few partition, sound insulation effect will be very poor.
The density and quality of particleboard are obviously higher than that of paper base. The sound insulation effect of excellent particleboard door can reach 32 dB, which is significantly higher than the national requirement of 22-25 dB.
As for the relatively high price of solid wood doors and solid wood composite doors, it depends on the density, weight of the wood itself and the thickness of the door panel. The higher the density, the heavier the weight and the thicker the door panel, the better the sound insulation effect.
