Nowadays, noise pollution is becoming more and more serious, which not only affects mood and hearing but also causes high blood pressure, heart disease, memory loss, inattention and other mental syndromes.
Studies have shown that human hearing can accept a volume of 30 decibels. When the continuous indoor noise pollution exceeds 30 decibels, normal sleep will be disturbed. If you continue to live in a noise environment above 70 decibels, your hearing and physical health will be affected. Will be affected.
In order to improve the noise problem, many people have installed sound insulation glass. What is sound insulation glass? What are the precautions for using soundproof glass?
Sound insulation glass is a kind of glass product that can shield sound to a certain extent. It is usually laminated glass with a double or multilayer composite structure. The sound insulation damping glue (membrane) in the middle plays a key role in the weakening and attenuation of sound transmission.
At present, insulating glass, vacuum glass, laminated glass, etc. are more common in the market.
1) Insulating glass is composed of two layers of glass, which uses the air part to absorb the energy of the medium and high-frequency sound vibrations, thereby reducing the sound level of sound waves. The sound insulation effect is relatively weak, with only a dozen decibels.
2) Vacuum glass is to seal two pieces of flat glass around, evacuate the gap and seal the exhaust hole. The gap between the two pieces of glass is 01-02mm. Generally, at least one of the two pieces of vacuum glass is low-emissivity Glass, so that the heat loss through the conduction, convection and radiation of vacuum glass is very low. This kind of glass is a relatively popular and professional soundproof glass in the current soundproof window market.
3) Laminated glass is generally composed of two layers of glass and film, and the materials used for the two layers of glass are different, which can block sound waves of different wavelengths. The film in the middle of the laminated glass is equivalent to a damping layer, which can effectively suppress the vibration of the glass, thereby improving the sound insulation performance of the glass. And the thickness of the glass is not large, the density is high, the higher the density, the better the sound insulation effect.
Precautions for using soundproof glass:
① After installing the sound insulation glass, tear off the protective film on the surface of the profile in time, and scrub it clean, otherwise a large amount of the protective film adhesive will remain on the profile, which is difficult to clean.
② When the side-hung top-hung window is in use, it can be opened differently by changing the handle direction of the switch. It is necessary to understand how to operate it to avoid damage.
③ When the sliding soundproof window is in use, the sliding track should be cleaned frequently to keep it clean to ensure that there is no dust and dirt on the track surface and groove.
