As long as there are neighbors, there will be noise hazards!
Including the top floor!
There is even "upstairs noise" on the top floor...
About 80% of the noise in the house is "footsteps, children running and jumping, dragging tables and chairs, heavy objects falling to the ground, shutting the door forcefully, air conditioning units, elevator noise..."
High-rise residences, semi-detached houses, townhouses, stacked villas, and large flats with one staircase and one household are all the same (except for single-family villas), and low-frequency noise is transmitted up and down many floors through the walls.
The decoration of the rough house is the most suitable for sound insulation, and the cost is the lowest (fine decoration and installed occupancy can be transformed into sound insulation).
Based on our years of governance experience:
Low-frequency noise is the most troubling;
Bedrooms have the most noise reduction needs;
It does not affect the rest at night, and it solves the noise problem for most people.
Process determines the effect
Low-frequency resonance is "solid sound transmission", where there is contact between solids and there is a sound bridge, which will cause resonance and cause the sound insulation material to fail, and sound will be transmitted through the surface of the sound insulation layer.
Noise reduction is a highly specialized discipline, not simply stacking sound insulation materials. It must rely on advanced noise reduction technology, otherwise step on the pit.
To control low-frequency resonance, we must first solve the resonance!
The boom and shock absorber are installed on the floor/wall, "there is contact and there is a sound bridge", the noise reduction effect is poor, "only the sound can be isolated, and the others cannot be isolated".
In 2012, the advanced "suspension process" developed for resonant noise is completely separated from the ceiling/wall, "no contact and no resonance", and the rigid connection between solids is disconnected through the air layer, and the sound bridge is completely cut off, and the "vibration isolation" is realized, which only needs 1 cm to save space.
The order of soundproofing
1. Set the plan before the start of the rough decoration;
2. Demolition and modification of walls and water and electricity installation need to be docked in advance;
3. Ground sound insulation in the masonry stage;
4. Ceiling and wall soundproofing in the carpentry stage.
Strictly speaking, "room in a room", first do the ground, then the wall and roof, and finally the door and window opening.
Room-in-room scheme
On the basis of shock-absorbing and sound-insulating ground, the ceiling and four walls are built to separate from the ceiling and the wall, completely cut off the sound bridge, and there is "no contact and no resonance" between the solids, and the noise reduction efficiency is maximized.
It is also the best solution to control the noise upstairs, the noise from the upper and lower sides, and the full frequency range and all-round noise reduction.
Vibration isolation is a technology, and after doing this, if you want better results, you just need to increase the amount of sound insulation. The thicker it is, the higher the sound insulation.
Case Overview
In the top floor, there are no upstairs neighbors on the top floor, but there will be "upstairs noise", and the low-frequency resonance of other floors will be noisy from the ceiling;
The downstairs noise is mainly controlled, and the ground is strengthened to "shock absorption and sound insulation"/"floating floor slab" scheme;
The four walls are very critical, choose a cost-effective solution;
The ceiling can be made ultra-thin, which mainly cooperates with the completion of the sound insulation integrity of the "room in the room";
The top of the bay window is staggered from the ceiling, and the main frame can be completed with wood in a small area, which is easy to operate;
The bay window is made of ultra-thin closing process, which belongs to the small process of the wall scheme.
Noise reduction schemes
The thickness of the ceiling is 9 cm: "1 cavity, 1 keel, 1 felt, 1 cotton, 2 boards";
The thickness of the wall is 9.6 cm: "1 cavity, 1 keel, 1 felt, 1 cotton, 3 boards, 1 film";
bay window 2.8 cm thickness "1 felt, 1 membrane, 2 plates";
The thickness of the ground is 1.8 cm, "2 felt, 1 film, 1 mat" (the screed layer is not included).
Guided installation
Quiet Home Soundproofing provides main materials, production plans, construction processes and technical support. The carpentry master invited by the main family, we guided the installation throughout the process and completed it successfully. Only the cost of materials and labor is the most cost-effective way to do sound insulation.
All of our success stories are guided installations.
Quiet Home is the first professional IP focusing on home noise reduction in the whole network, constantly upgrading and improving the noise reduction process, designing and developing better materials, and making better results, which is the significance of our choice of noise reduction business.

"Super Coffee Cotton"
The first-level sound absorption coefficient is highly effective for noise reduction, and the high bulk density of 100K greatly improves the noise reduction effect, and the tin foil enhances the noise reduction effect.
The material is soft, the dust is very small, no itching or pricking, environmental protection and no odor; the first class noise reduction of the aircraft is of the same quality, mainly exported to Australia, Europe, etc.;
4cm thickness for home decoration, keel center spacing of the same width, easy to install, easy to achieve seamless close assembly, compatible with all processes on the market, I-shaped aluminum, cassette keel, light steel keel, wood keel universal;
Inorganic material, flame retardant class A non-combustion, waterproof, moisture-proof, mildew-proof, stable structure for 30 years, top household environmental protection soundproof cotton.
Why is polyester soundproof cotton useless?
Only the second-level sound absorption coefficient has poor noise reduction performance;
The density of the rolled cotton is low, and the effect of low-frequency noise control is equal to 0;
The material of the clothes, the fiber is too coarse and hard to cut and smooth, and the gap between the cotton and the cotton will leak;
It is easy to age, and after a few years, it will oxidize and become brittle and fail;
The fire rating is low, and commercial spaces with fire protection requirements are prohibited;
