resonance noise control, first absorb shock and then sound insulation. Shock absorption is not good, sound insulation is invalid.
suspension shock absorption and noise reduction process "no shock" beyond the level of "reducing vibration".
For example, ceiling sound insulation:
1. The layman uses a hanging rod to fix it to the ceiling, which is a sound bridge, which will definitely conduct resonance, resulting in many netizens' feedback that "the voice has decreased, and the sound of footsteps has not decreased."
2. The principle of ceiling shock absorber is to reduce vibration, which can only reduce and cannot cut off the sound bridge.
3. The suspended ceiling has no contact with the ceiling, and without conduction it means "no vibration". Since its development and application in 2012, multiple versions have been upgraded and improved, and are currently the latest version. Compared with the classic suspension process, the same solution: the load bearing is reduced by 15 catties/square, the thickness is reduced by 2 cm, the sound absorption effect is enhanced, the 2 processes are reduced, and the installation is simpler...
also has a huge advantage: the ceiling and walls only need 9 cm thickness to create an overall suspended structure in the room, which is completely separated from the ceiling and walls, without any contact, and completely disconnect the sound bridge. It is currently the most effective solution for the management of " resonance noise" in the field of home sound insulation. New suspension is not perfect either. The space with a large span must be made of classic suspension technology. The two versions complement each other in terms of advantages and will be promoted and used simultaneously in the future.
How much does it cost to make a floating "house in the room"?
Take a bedroom with a floor height of 2.8 meters as an example:
[Ultra-thin solution] sound insulation material "1 cotton 1 felt"; the overall noise reduction is about 50% to 60%.
"Ceve" thickness is 9 cm; "wall" thickness is 8.8 cm;
all materials cost about 1.4W. (Including utilization rate 10%)
[Standard Solution] Soundproofing material ceiling "2 cotton 2 felt", wall "1 cotton 2 felt"; overall noise reduction is about 6 to 70%;
"ceiling" thickness is 14 cm; "wall" thickness is 9.2 cm;
All materials cost about 1.9W. (Including utilization rate 10%)
main materials: Spain imported Tecsound environmentally friendly sound insulation felt, customized 80k bulk weight, formaldehyde-free sound insulation cotton , hot-dip galvanized steel, customized aluminum, auxiliary keel, vertical keel, woodworking board, gypsum board, moisture-proof film, etc.
Make a "room in the room" based on floating floor slab , elastic floor, and suspended ground, with the most ideal effect.
If the ground is not done, can you build a room in the room?
1. The resonant noise is transmitted from the upper floor, and it is mainly concentrated on the wall and ceiling;
2. The suspended ceiling and wall can be installed in the independent suspended structure of "room in the room", which also achieves the ideal effect of "vibration-free";
3. The "room in the room" can be split and used separately, and the core is a "independent whole", which has no contact with the ceiling and wall, completely cut off the sound bridge and no resonance. As long as the sound insulation level is done, it is a very simple operation.
"Quiet home sound insulation" - only make high-quality home environmentally friendly sound insulation.
