The house is not well insulated, how should it be soundproofed? What to look out for?

I believe that everyone has the experience of being tormented by the poor sound insulation of the house. Poor soundproofing of the house will affect the daily life and routine of yourself and your family. Next, I will tell you how to do sound insulation and the problems that need to be paid attention to.

1.Wooden floors are laid

Wooden flooring is much better soundproofing than other types of flooring. Even if we walk quickly on the floor, we don't make a lot of noise. Because the holes in the wood fiber are effective in absorbing the noise of life, laying wooden floors is a good way to insulate sound.

We can also lay blankets on the floor, which are not only very soft to the touch, but also reduce the sound of walking. <>

2.Installation of soundproofing materials

When we decorate a house, we should consider installing soundproofing materials on the walls. The mechanism of sound insulation materials is that there are many tiny pores inside the material, and sound will enter these pores into the interior of the material, and friction with the material will convert sound energy into heat energy. Sound insulation materials generally include centrifugal glass wool, rock wool, plant fiber spraying, etc.

Try not to have gaps in the wall, which will greatly reduce the sound insulation effect of the wall. <>

3.Install double glazing

In order to significantly improve the sound insulation, we need to increase the number of compartments. The two layers of glass form a resonance system with the air in between, so that the sound insulation effect is greatly enhanced.

4.Install the ceiling

Some of the noise in life also comes from upstairs, and people upstairs will make sounds when they move things or walk. Installing a ceiling can greatly reduce noise, and we can also install some soundproofing materials on the ceiling, so that the effect will be a little better. <>

5.Install wooden doors

The pores of the wood can absorb noise well, so the sound insulation effect of installing wooden doors will be better. If there is a large gap between the door and the wall in your home, consider putting some seals on it.

By decorating walls, floors and ceilings, noise can be effectively reduced. If a neighbor makes a noise, we need to be considerate, because it is an inevitable thing in life.

If you want to do sound insulation, you can add a ceiling or a soundproof floor, and the floor or wall can also be covered with foam or sponge can be soundproofed.

The sound insulation is not good, then first of all, you should make a partition, so that you can isolate the sound on the opposite side well, so what you should pay attention to is to choose a better sound insulation product.

The sound insulation is not good, you can make a soundproof board in the middle, so as to achieve the desired effect, but you should also pay attention to the soundproof board, not too thick, not more than two millimeters.

If we want good sound insulation, we can start with doors and windows. Because the noise is transmitted to the room through doors and windows, it is necessary to choose doors and windows with sound insulation effect, for example, we can choose multi-layer glass composition, and at the same time, the gap between the window frame should be sealed to achieve the purpose of noise reduction. The material of the window is made of broken bridge aluminum or plastic steel, and in order to make the effect more prominent, we can choose slightly thicker curtains to decorate the window.

Window soundproofing is usually a double-glazed window. You can keep the existing window and add another window; Or remove the existing windows and reinstall a glass designed according to the new standard, all of which are the same thickness and have the same resonant frequency. This makes the sound around that frequency stand out.

In general, the interval between the two layers of windows should be 20cm-30cm. To achieve the same -50db sound insulation as a concrete wall, it is best to have a separation of more than 30cm between the two layers of glass. It would be nice if you could take some more sound-absorbing measures in this interval.

You can add soundproof cotton to the wall, or add foam or sponge to the wall, or install professional soundproof glass, so as to improve the sealing degree of the room; The soundproof glass of the bedroom, the vacuum glass can meet the requirements of sound insulation, the bedroom soundproof window frame, the plastic profile material will be thicker, so the sound insulation and heat insulation effect is very good.

1. The best way to insulate windows: The best way to prevent the sound from coming in is to replace the windows with double-glazed windows, which can effectively prevent the sound from coming in.

2. The easiest way to insulate windows: buy some hairspray or glass glue, that is, use hairspray to make a circle around the window, and then make a soundproof sealing strip for the window and window, and paste the window bend film.

3. The easiest way to insulate the wall: you can paste blanket-shaped wallpaper on the surrounding walls, which can well prevent the sound from coming in, just like in the hotel, which is simple and convenient.

4. Medium method of wall sound insulation: For the wall of non-solid wall, a wooden keel partition can be carried out, and then a large triangle plate can be nailed to it. Or you can also place sound-absorbing cotton inside the wooden keel, and paste blanket wallpaper and three splints outside, the effect is very good.

5. The best way to insulate the wall: In addition, the best way is to directly remove the partition wall, make the partition into a cement wall, and then paint, paste wallpaper, etc., which can better prevent the sound from coming in, but it is more time-consuming and laborious.

How to remedy the poor soundproofing of the house.

1. The ceiling can be suspended

If the room is to be soundproofed, the ceiling can be installed on the ceiling first, which can effectively reduce the delay noise, and can also achieve heat preservation, heat insulation and other functions.

2. The carpet can be soundproofed

Secondly, the carpet can also achieve good sound insulation, because the carpet material is soft, mainly made of fabric or wool fleece, which can prevent noise from coming out, reduce noise decibels, and enhance the sound insulation effect of the carpet.

3. You can use wallpapers:

Similarly, putting wallpaper on the walls or roof of a house can also reduce noise to a certain extent. Especially the kind of wallpaper with textures and unevenness, it can change the direction of sound propagation, so as to play a sound insulation effect.

4. Double layer for window glass:

How to remedy the poor sound insulation of the room? The most important thing is the interior windows, the windows of the room must be installed with double glazing, if it is a simple window glass, the sound insulation effect is not so good.

5. Put more green plants:

If the room is to be soundproofed, you can also put some green plants, and plants can also reduce noise. In addition, placing green plants in the room can also play a role in purifying the air and improving the environment.

Doors should be soundproofed, windows should be soundproofed, ceilings and walls should be soundproofed, and bathroom sewers should be covered with soundproof cotton.

First, the door should be soundproofed

In fact, the key to sound insulation in the home is the door, after all, the door is not only the key to your entry and exit indoors, but also the main channel for noise transmission, so when choosing a door, the sound insulation performance must be taken into account. It is recommended to choose the kind of solid wood composite door, and the interior should be preferably mechanically constructed of the bridge tunnel, so that it can not only ensure durability and durability, but also play a role in sound insulation and noise reduction to a certain extent. If you are not at ease, you can add a mute strip under the door, and a sound insulation strip can also be added around the door frame, with the T-shaped structure on the edge of the door leaf, which can not only fully increase the sound insulation ability, but also play a role in preventing insects and shading light.

2. Window sound insulation

Naturally, windows should also be soundproofed, and for outdoor noise, windows can be said to be the only line of defense; It is recommended that even if the house is not on the road, the windows should be made soundproof. Just remember to choose hollow broken bridge aluminum window sashes, and choose double-layer laminated glass for glass, so that the intrusion of outdoor noise can be fully avoided, and the noise suppression is obvious after opening and closing the window. At the same time, such a window sash has a very good thermal insulation, which can be said to kill multiple birds with one stone.

3. Ceiling and wall sound insulation

If the indoor sound insulation is still very general after the above two points are done, then it means that the sound insulation of the house itself is very poor, so I have to make a fuss from the ceiling and wall. Here we can use the kind of soundproofing materials such as soundproofing felt, sound-absorbing cotton and other soundproofing materials to stick on the wall or ceiling, the soundproofing effect is very good, but I have to warn everyone that it will slightly compress the indoor space.

Fourth, the toilet sewer package soundproof cotton

The last point is actually mainly the sound insulation in the bathroom, sometimes you can often hear the sound of flushing upstairs, and even the sound of talking in the bathroom in serious cases, which is because the sewer is not covered with soundproof cotton, and the sound comes to your home along the pipe.

You can use a spiral silencing pipe, and at the same time wrap the pipe with soundproof cotton on the outside, and then use bricks to build the pipe, so that even if you go to the toilet upstairs in the middle of the night, it will not disturb you. In fact, these problems are not only related to the living environment, but also to the sound insulation design when decorating the home.
