What is the poor sound insulation effect of broken bridge aluminum window? How did the master solve it?

In the first method, we need to start with the wall. The conventional practice here is to soundproof the walls. The most traditional way of wall insulation is to do external wall insulation. The noise reduction effect of insulating glass is relatively poor, and the sound insulation effect of three-layer insulating glass is slightly better than that of double-layer insulating glass. It can be considered to use double-layer sandwich hollow sound insulation glass. The sandwich layer filters low-frequency noise, and the hollow layer filters high-frequency noise. Ordinary single-layer glass can not achieve good sound insulation effect, while vacuum glass can achieve very good sound insulation requirements. The air in the middle of the double glass also blocks the way of sound propagation, which has a good noise reduction effect.

If this kind of window is not soundproof, first check whether the window is closed tightly, and then see whether the sealing strip is aging, deformed or falling off, or whether the sealant on the wall of the window frame has cracks. Anyway, there must be a crack. Find the reason, deal with the symptoms, and solve it immediately. If it is a plastic-steel sliding window, there is no large-scale deformation. Check the periphery of the window frame first to see if the sealant has shrunk and fallen off seriously. In most cases, there must be. Shovel off your foot and seal it. The window is double-glazed, but sleeping on the side of the road is very noisy. Is there any good way to reduce noise? I gave the answer: living near the highway, it is definitely impossible to have two broken windows. It is recommended to install three broken aluminum glass windows.

For example, some sections of the expressway will have noise barriers, which are lighter than those without noise. If there is a building in front, the noise will be much lighter, because the wall can play a good role in sound insulation. Houses can be solved in many ways, such as adding another layer of windows outside the windows and installing sound insulation films and curtains on the balcony. The pharmacist's real sound insulation is very important to the choice of glass. My house is also double-glazed, but the sound will come from under or on both sides of the slide rail of the window. I bought a soundproof cotton sticker online, 8 yuan12m, and put it all on the window. Don't say, the effect is really good!
