It is understood that building materials with good sound insulation effect generally need to meet the characteristics of dense and smooth surface. If the house itself has many light walls and poor sound insulation effect, it can be remedied in the later decoration process, such as choosing doors and windows with good sound insulation effect. At present, it is more popular to use hollow double-glazed windows, choose high-quality fire-proof and sound-proof doors and use fabric decoration. The thicker the fabric ornaments such as curtains, the better the sound insulation effect. The floor can be carpeted to reduce noise.
Sound insulation affects life. The child is running at home, go upstairs and look for it.
The house of Mr. Bai's family is a multi-storey residence that was handed over in 2005. My 3-year-old son often runs around the house barefoot, and sometimes he jumps happily on the living room or bedroom floor. "This jump doesn't matter, attracting people downstairs to find it, saying that the movement is too big to affect them." Mr. Bai said that it is common to explain an apology, but there is nothing she can do because the child takes the initiative. She understands the distress of her neighbors downstairs and is often woken up by the footsteps upstairs at night-the floor has poor sound insulation effect, so she can only be careful at home in order to affect others less.
Upstairs, the bottle fell and the sound was clear.
Ms. Li's home is a multi-storey house built around 2007, and she also feels that the sound insulation effect of the house is too poor. "If the wine bottle upstairs falls to the ground, I can hear it clearly at home." Ms. Li said, "If there are guests wearing high heels at home above, the sound of walking will be too harsh."
The poor sound insulation of residential buildings is mainly reflected in two parts: one is the partition wall related to the left and right neighbors, and the other is the partition wall floor related to the upper and lower neighbors.
The whispers in the next room can be heard (it's a big deal)
Mr. Zhang bought a high-rise apartment in the central city around 20 10. He said that in the dead of night, you can hear the sound of the TV next door in the bedroom, and sometimes you can hear the sound of the bedroom next door. Mr. Zhang is worried: can he and his wife whisper in the next bedroom?
How to identify the sound insulation effect of a house?
(1) Wall structure, brick consumption and wall thickness are more important.
How to check the sound insulation effect when buying a house? The thicker the wall, the better the sound insulation effect. If the wall is not thick enough, you can clearly hear the crying of the child next door by flushing the toilet upstairs and dropping chopsticks. At present, there are the following standards for the thickness of residential walls: "Sanqi Wall" and "Si Er Wall".
The current wall thickness is determined by the length of the brick, which is usually used as follows:
Semi-brick wall: the drawing is marked as 120mm, and the actual thickness is115mm;
Brick wall: the drawing is marked as 240mm, and the actual thickness is 240mm.
One brick and a half wall: the drawing is marked as 370mm, and the actual thickness is 365mm；;
The second brick wall: the drawing is marked as 490mm, and the actual thickness is 490 mm.
3/4 brick wall: the drawing is marked as 180mm, and the actual thickness is 180mm.
When the reinforced concrete slab wall is used as a load-bearing wall, its thickness is 160mm or180mm; ; When it is used as a partition wall, its thickness is 50 mm, when the aerated concrete wall is used as a peripheral wall, it is usually 200 mm ~ 250 mm, and when it is used as a partition wall, it is100 mm ~150 mm.
(2) Houses facing the street should be cautious.
Road traffic noise comes and goes. Living in a noisy environment for a long time is easy to go crazy, and more seriously it will lead to neurasthenia.
(3) Attention should be paid to the green belt in the community.
Green belt is a natural noise barrier. Check whether there is a green belt near the community and whether the steps between buildings are reasonable.
(4) High-rise buildings should be cautious
Many people like high-rise buildings when buying a house, because they think high floors will have better views. But the higher the floor, the higher the price and the better the view, but the stronger the wind, the louder the noise.
What are the remedies for poor sound insulation?
1, wall treatment
Some wall treatment methods can be used to achieve sound insulation effect. For example, some houses now use lightweight bricks as walls, and these materials have poor sealing performance. If the noise along the road has a great influence, a layer of light steel gypsum board with sound-absorbing cotton interlayer can be made on the wall near the road, which can solve the sound insulation problem to a great extent.
The new house has just moved in. Be careful. Wall has ears.
Step 2 close the window
The best way to deal with noise is to close the window tightly. Whether it is a single-layer window or a double-layer window, sealing is the most important. Relatively speaking, the sealing performance of aluminum alloy windows is worse than that of plastic steel windows.
The new house has just moved in. Be careful. Wall has ears.
3. Decorate with wooden "background wall"
Be careful when making TV background walls, especially thin wooden ones. "When the thin board shakes, the wall that sticks to it also shakes, and the noise is spread out." The floor is the weakest in noise prevention. If residents spread the floor, the noise will be absorbed. If the floor tiles are smooth, "the chances of hearing your voice downstairs are higher."
4, ceiling sound insulation treatment
When installing the ceiling, sound insulation can be carried out, which can prevent the impact sound upstairs to a certain extent.
5. Add soundproof doors and windows.
In order to prevent outdoor noise, soundproof doors and windows can be installed.
