2, the window seal is solved, the next step is to make it more sealed, after all, sound insulation does not mean sealing, but also depends on sealing performance. It is a very effective way to use the special glass used in the spacecraft on the sound insulation window of Jingmeijia. Because the loudest part is often the treble, and the treble travels in a straight line and most of it can be reflected by the glass.
It is also a simple way to use thick curtains to consume some sound energy, but it is certainly not a very effective way.
We can use carpets, cloth and even sound-absorbing cotton to reduce their indoor influence. Rubber pads at the foot of the bed can also reduce vibration. At the same time, mattresses with palm pads are better than Simmons with springs, not to mention hard beds.
5. Now some houses use light bricks (hollow bricks) as external walls, which have poor sealing performance. If your roadside has a great influence on you, you can also make a sandwich of wood square (light steel) and sound-absorbing (sound-insulating) cotton with gypsum board on the wall near the road, and then decorate the surface with wallpaper (of course, you can also treat the surface with ordinary wall paint).
6, of course, no matter how to do sound insulation, don't forget proper ventilation, too closed environment is as unhealthy as sleep. The side facing the noise should prevent noise, and the opposite side should be properly ventilated. Of course, you don't necessarily have to open your windows properly, because noisy things have certain repercussions, which may affect the building behind you and spread back to your building.
