It was too loud when moving the bench. How can there be no sound?

This situation is especially aimed at some post-masonry brick walls. The mortar joint is not full in the process of brick wall masonry. Whether insulation is done or not, then the noise situation is very serious. Like the sound of traffic, the noise reduction effect of double-layer insulating glass is poor, and the sound insulation effect of triple-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. Only changing the soundproof window and changing the glass is the most practical and effective way. The soundproof window has a specially treated soundproof layer, which can not only play the role of heat preservation, but also fully absorb the sound waves passing through the glass and isolate the noise in each frequency band to the greatest extent.

Then check the window sash sealing strip, and replace it immediately if it falls off seriously. Finally, check the seam between the screen window and the window frame. If there is obvious air leakage, external sealing strips should be used for treatment. In this case, there will be many changes. Windows are basically sliding windows with sealing strips to reduce noise, so as long as the windows are locked, more than 80% of noise can be blocked, and the effect will be better if the windows are double-layer vacuum glass.

The windows at home are double-glazed windows, 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. Traffic noise comes from the sound of car tires rubbing against the ground. Cement road is more serious than asphalt road, such as the sound of automobile engine and exhaust pipe, automobile horn, wind resistance, braking, speed bump and so on. After all, some old people are not as energetic as young people. Now some young people still like nightlife, but the elderly and some people who don't like chaos can't live in such an environment. Changing the environment is definitely a problem that can be completely solved.
