The houses are stronger today than ever and everyone wants things calmer. The question is what to do? Obviously, nobody wants to spend money in soundproofing, just to spend time and money in vain, and still hear much noise.
Sound insulation is science, not magic, and as such, is possible to outline a basis of the basic principles that define the sound insulation in any given situation. There are only a few basic principles governing the isolation the sound of any wall, floor or ceiling.
Principle # 1: Mass Mass prevents the transmission of sound in a simple way - it is harder for the sound of shake something very heavy that something very light, it is different from saying that it is harder to push a cart full of lead bricks that an empty cart. However, for make major changes in performance that has to make very large changes in mass.
Principle # 2: Decoupling Think of a typical wall. He has a stud panels plaster on each side. If the hammer of plaster in the room # 1, which will take place through the vibration of masonry, in stud, and directly on the plate Plaster Room # 2, where it is converted back into sound. This is a very stiff the next wall, excellent sound conduction.
Dissociation is very simply disconnect this rigid connection by inserting a space or something elastic like rubber, neoprene between a layer of drywall and the stud. The Products are available in the market to do this, such as sound clips and resilience resilient channels.
If this is new construction you really should consider staggered stud or double stud construction that isolation is necessary. Usually less expensive and more efficient than commercial products mentioned above.
These techniques all functions by inhibiting the movement of sound from one side of the wall to the other through paths mechanics (like studs or beams). In contrast, the vibration has to pass through the air cavity between the studs, where some of them will be lost, and isolation, absorbent material, where (at higher frequencies), many of them will be lost.
Principle # 3: Absorption This isolation is accomplished with simple, such as cellulose, fiberglass and mineral wool (wool). Exotic ($ $) isolates are also available. Foams are not a good product to use to absorb the sound. The foam is excellent for thermal purposes, but no sound.
Installing insulation in a wall or ceiling cavity increases the sound leakage due to delete / remove / destroy any sound. An important note is that the insulation loses its effectiveness at very low frequencies. Put some fiberglass front of a loudspeaker at home and hear the sound drop. Put it that isolation against a subwoofer and you can not hear any difference at all.
Insulation is important, but not very effective if it is the only technique used.
Principle # 4: Attenuation This is not to wet the wall. A damp, something to reduce capacity to perform a vibration. A steel tube sound drives well, is not well damped. Masonry, subfloor and most building materials are not well damped. There absorbent materials known as viscoelastic can be very easily and economically applied between two sheets of standard drywall and subsoil and are highly effective.
Principal # 5: Be sure to caulk seal around all openings such as outlets and windows. Seal doors with weatherstripping. Installation line ducts in the ducts. All this helps to keep the sound input and output.
