What is a soundproof window?

Sound insulation glass of soundproof window is a kind of glass product that plays a certain sound-proof role. Acoustical windows are usually double-layer or multi-layer damping glass, and the sound insulation damping glue (film) in the middle of laminated glass plays a key role in weakening and attenuating sound propagation. Glass products with sound insulation function include shock-absorbing glass. Do you know what the sound insulation principle of sound insulation glass is?

Sound insulation principle of sound insulation window sound insulation glass;

Various outdoor sound sources produce vibration and noise, and the noise propagates through the air medium. When the noise reaches the doors and windows of sound insulation glass, it is attenuated by sound insulation glass. Especially when the noise passes through the sound insulation and damping glue, the medium-frequency noise and low-frequency noise are absorbed, distorted, damped and attenuated by the sound insulation and damping glue, which can effectively filter out the medium-frequency noise and low-frequency noise, and finally the noise entering the room is only about 5%. The "low-and medium-frequency noises" and "deep", which are common, annoying and can't sleep, are basically gone and almost inaudible. The feeling indoors suddenly became soft, and it was much more comfortable to stay indoors. As the saying goes: living in the downtown area and living in the countryside will come true.

Sound insulation glass is a kind of glass product which plays a certain role in shielding sound. Usually it is double-layer or multi-layer laminated glass, and the sound insulation and damping glue in the middle of laminated glass plays a key role in weakening and attenuating sound propagation. The general laminated glass is actually a PVB intermediate film with polyvinyl butyral as the main component. But the professional sound insulation glass interlayer is a sound insulation film, which plays a key role in weakening and filtering sound propagation. Glass products with sound insulation function are actually a kind of laminated glass. The softer and more elastic the sound insulation film in laminated glass is, the more it can increase the sound insulation damping coefficient of laminated glass, thus improving the sound insulation ability of laminated glass. The sound insulation capacity of ordinary PVB glass is only 28-34 decibels, and the sound insulation capacity of sound insulation film can reach 35-40 decibels or even higher.

To sum up, it is sound insulation glass's sound insulation principle. The sound frequency is sound insulation, and the noise can be divided into:: 1000Hz high frequency noise.
