No one lives upstairs, but you will hear the sound of knocking at the door? How to make the house soundproof better? Living in a building does have many benefits, but sometimes there will be some problems that have not been encountered before, such as abnormal noise. Sometimes, although no one lives upstairs, it does make some noises occasionally. For some superstitious people, they are even afraid to attend the meeting, but this is actually a phenomenon. Then the problem comes. No one lives upstairs, but you will hear a knock at the door. How to make the house soundproof better?

No one lives upstairs, but you will hear a knock at the door?

1, the sound source is not inside the wall, but outside it. Considering that many people don't live upstairs at all, they all sound like marbles. The sound source must be in the wall, and the things in the wall are cement, water pipes, steel bars and wires. Now that hot account and cold contraction have been ruled out, this is a logical explanation.

2, very common, of course, sometimes not upstairs, because solids can also spread sound, probably from other rooms through the stairs, just like the sound upstairs.

3. According to the physical principle, the propagation of sound needs medium. Different media have different communication effects. This problem may be because the building materials in your home are not up to standard, and the standard countries have detailed regulations.

How to make the house soundproof better?

1, rough walls

The main reason for indoor echo is that the walls are smooth. The principle of echo is similar to the reflection of light, and smooth walls can reflect. Therefore, roughening the wall is an effective way to reduce indoor echo. For example, the decoration materials of cultural stone will make the wall rough. In addition, the selection of sound insulation materials in wall and ceiling decoration can also achieve good results.

However, for those who rent out, these methods seem a bit difficult to practice. However, in addition to improving the annoying indoor echo from the wall decoration materials, pasting wallpaper on the wall can also reduce the indoor echo.

2. Install thicker doors and windows

Generally speaking, the environmental noise mainly comes from window cracks, especially the upper, lower and middle cracks. In most cases, the installation of single-layer hollow glass windows with better materials can achieve better sound insulation effect. For people living by the road, it is particularly necessary to install double-layer hollow glass windows with better sound insulation effect.

In fact, the double-layer hollow glass window has one more layer of hollow glass than the single-layer hollow glass window, and there is a vacuum layer between the two sides of the glass, which can isolate the transmission of sound. Usually, the soundproof window larger than 1 mm is better. The sound insulation effect of windows will also be affected by other factors, such as air tightness. So try to choose doors and windows with good air tightness.

I see. No one lives upstairs, but you will hear a knock at the door? The problem of how to soundproof the house is that the sound coming from the building is normal, because many times the material of the house will change substantially because of the weather or age. As the change takes place, there will be a sound slowly. If it is not acceptable, some better sound insulation methods can be used to deal with it, and the effect is in line with everyone's expectations.
