Sound insulation effect of sound insulation board and sound insulation doors and windows

Sound insulation method is to isolate the sound source from the surrounding environment with certain sound insulation materials, so that the noise radiated by it cannot directly spread to the surrounding area, thus achieving the purpose of controlling noise. The essence of sound insulation is to attenuate the sound radiated by the sound source as much as possible. Common measures are sound insulation materials and sound insulation structures.

sound boarding

The higher the density, the better the sound insulation effect. A board made of this material is called a sound insulation board.

soundproof door and windows

As a sound insulation measure for windows, the structure of double-layer windows is usually adopted. Nowadays, more and more double-layer security doors have good sound insulation characteristics.

Sound insulation effect

The worst sound insulation effect is the doors installed in general collective apartments and simple family decoration. There is a big gap between the door and the door frame. Plywood nails are used for rough land construction, and its sound insulation characteristics are at most-15dB. The sound insulation characteristics of general residential doors can reach -25dB~-35dB.
