What are the reasons for the poor sound insulation of high-rise buildings and how to solve the problem of poor sound insulation effect of houses?

High-rise buildings generally use pouring, and at the same time, it will also do the effect of heat preservation and sound insulation. If the owner finds that the sound insulation effect of the high-rise building is poor, it means that the house was built by cutting corners and the developer saved costs. What is the reason for the poor sound insulation of high-rise buildings? How to solve the poor sound insulation effect of the house? Let's take a look together.

What is the reason for the poor sound insulation of high-rise buildings?

1, the smooth wall is too thin.

If the house does not meet the sound insulation requirements, it may be on the light wall. If the light wall is too thin, the sound insulation effect will be poor, especially some light walls with circuit cassettes or slotted waterways. If both sides of the decoration are on the same wall, this kind of love is basically the same, so the sound insulation effect is not good. If that's the case, I suggest that it will be much better to do sound insulation when laying on the ground.

2. Cut corners and save costs

Generally speaking, there will be no such serious problems. If the sound heard upstairs and downstairs is clear, it means that the house was built by cutting corners and the developer saved costs. High-rise floors are generally poured, and at the same time, they also have the effect of heat preservation and sound insulation, and so on. In this case, the requirements of sound insulation can be met.

3. Flue * * *

The last case is the use of flue. Bian Xiao's friend's house is such a house. As long as others start cooking, the kitchen will be noisy and you can smell others cooking. Therefore, we should be optimistic when we look at the house. If the house is too noisy, it will affect the quality of our home life.

When the house is completed and accepted, the state has strict acceptance standards for thermal insulation, but there is no specific requirement for sound insulation. There is no requirement that developers will not spend great efforts on sound insulation and spend some unnecessary thoughts.

As we all know, the current high-rise residential buildings are all frame structures, and the subsequent division and filling are all made of aerated bricks. The core tube is a cast-in-place solid wall with a thickness of more than 200 mm. The sound insulation capacity of the concrete wall with a thickness of 200mm is more than 48dB, and that of the reinforced concrete perforated floor with a bearing capacity of 200kg/m2 is less than 45dB.

Then let's take a look at the block walls commonly used in buildings now, including load-bearing and non-load-bearing blocks. Commonly used blocks mainly include ceramsite, fly ash, slag, sandstone and other concrete hollow and solid blocks. Generally speaking, hollow blocks are used for external wall insulation. There are a lot of pores in the hollow block, which are filled with gas with weak fluidity. Gas is a poor conductor of heat, so the heat preservation effect is good.

The indoor partition adopts solid blocks, and the sound insulation capacity of the wall changes with the weight and thickness of the wall. The sound insulation performance of the filled block partition wall depends largely on the thickness of the plastering layer on the wall.

How to solve the poor sound insulation effect of the house

1. The sound insulation effect of the house is poor. You can check the sound insulation of the window. If it is caused by a large window gap, you can stick a soundproof seal to block the window gap. If the window is not soundproof, you can put a soundproof film on it. Sound insulation film can play a certain sound insulation effect without affecting indoor lighting.

2. You can also remove the window with poor sound insulation effect and reinstall the sound insulation window. If there is enough space on the windowsill and the noise is not particularly serious, you can also consider installing another plastic steel window. When installing windows, consider choosing casement windows for better sealing performance; The distance between two windows should be greater than10cm.

3. If there is a lot of noise upstairs, you can consider installing a ceiling for sound insulation. When installing the soundproof ceiling, everyone should pay attention to the need to add soundproof materials such as soundproof felt on the keel, and the thickness of gypsum board should be above 8.5mm, so that the ceiling can have good soundproof effect.

In addition, we can improve the sound insulation effect of the wall. For example, we can install polyester fiber sound-absorbing board on the wall, make soft bags on the wall and stick cork boards on the wall to absorb noise. Or try to make the wall as rough as possible, so as to reduce noise, such as decorating the wall with cultural stones, pasting wall covering wallpaper with deep texture, and so on.
