How to make sound insulation when it is too noisy upstairs?

Commonly used window materials are aluminum alloy and plastic-steel materials. Comparatively speaking, plastic-steel materials have good sound insulation effect. As for glass, you can choose tempered glass. If you want better sound insulation, you can also choose vacuum glass.

2. Cotton filler

There are many kinds of sound insulation cotton to choose from, such as glass wool, rock wool, mineral wool, polyester cotton and so on. You can use environmentally friendly polyester sound-absorbing cotton and choose materials that can be flame retardant.

Step 3: doors

This door should be soundproof. In addition to the tightness after opening the door, the quality of the door panel is also very important. The sound insulation effect of the door panel mainly depends on the filler in the door core. The higher the density and weight of wood itself, the thicker the door panel and the better the sound insulation effect of the door.

4, soundproof ceiling

Making soundproof ceiling can reduce some noise, but it can't be completely isolated. The soundproof ceiling is made of sound-absorbing materials, which can absorb sound energy and reduce noise. But if it is an old house, the effect of soundproof ceiling will be worse. There are pipes in the wall of the old house, and even if there is a soundproof ceiling, the sound can come from the wall.

5. Vibration reduction

Sound is transmitted by vibration, and eliminating vibration is an important work in sound insulation engineering. Wall dampers and ceiling dampers can not only reduce the amplitude, but also avoid acoustic bridge. There is also a floor cushion used on the ground, which can play the role of sound insulation and shock absorption on the ground.
