What is the sound insulation principle of soundproof window? What kind of soundproof window works well?

Now the noise pollution in big cities is very serious, so many people will choose to install sound insulation glass at home. Next, Bian Xiao will tell you the sound insulation principle of soundproof windows and what kind of soundproof windows are effective.

1. What is the sound insulation principle of the sound insulation window?

1, which is composed of double-layer or triple-layer sound insulation glass.

Ordinary windows have only one layer of glass. The soundproof window has at least two layers of glass, many of which are three layers. Multi-layer insulating glass with different thickness can effectively reduce the noise intensity.

2, window frame filled with sound-absorbing materials

The bedstead of the soundproof window is filled with sound-absorbing materials, which can effectively absorb sound waves and effectively isolate noise in various frequency bands.

3. Adopt the cavity structure of heat insulation broken bridge aluminum profile.

According to the indoor and outdoor noise situation, the cavity structure of heat insulation broken bridge aluminum profile can effectively reduce the vibration effect of sound waves, prevent the spread of sound, and reduce the noise by more than 35dB.

4. Sealing rubber strips are added between sound insulation layers.

Between the sound insulation layers of the sound insulation window, the sealing rubber strip on the edge of the aluminum alloy partition frame, the design of rubber angle and the glue injection process all effectively ensure the sound insulation effect of the window.

Second, what kind of soundproof window works well?

1, vacuum sound insulation glass

There is almost no air in the middle of the vacuum glass, and the two pieces of glass are close together, so the sound insulation effect is not obvious, and the heat insulation is very good, so the vacuum degree cannot be maintained for a long time.

2. Hollow sound insulation glass

The middle of the hollow sound insulation glass is filled with an air layer of 6-9 mm, and the periphery of the glass is bonded and sealed with sealing strips and high-strength and high-airtightness composite adhesive tapes. High-frequency noise such as human voice in insulating glass and tweeter in school has good sound insulation performance, but it has no obvious effect on low-frequency traffic noise such as bus engine noise, train noise and plane noise.

3. Sandwich sound insulation glass

Laminated glass is also called KK superelastic glass by many friends, which is mainly composed of KK superelastic interlayer or PVB interlayer. Laminated glass can play a sound insulation effect, mainly through the adjustment of the composition of the intermediate film, after professional technical treatment.

4.DOK polyester sunshade mute glass

DOK polyester sunshade and mute glass is a new type of sound insulation glass, which is made of transparent polymer material and has superior sound absorption and sound insulation performance of the wall, thus achieving sound insulation effect. The soundproof window made of DOK polyester sunshade mute glass not only has sound insulation effect, but also has the functions of anti-theft and anti-hurricane earthquake.

The above is the introduction of soundproof window. A good soundproof window is conducive to creating a quieter and more comfortable environment. Friends in need can consider it. I hope the above content will be helpful to everyone.
