To improve the soundproofing, first determine what the noise is.
To know how to sound your room, it is important first to determine the source of the noise that disturbs you. There are three types of noise :
• Airborne noises (or noises moving in the air) eg television, radio, voices
• Impact noise (or noises emitted during a contact )
• Urban and rural noises (or external noises whose vibrations are transmitted through the walls) eg a train, a tramway, a busy road.
These three types of sounds are very different and can be annoying depending, in your living room or in the rooms.
Choosing flexible and porous materials for good soundproofing
The principle of soundproofing is similar for all noises: the vibrations are stopped by sound insulating materials, which will prevent the sounds from coming out or entering.
It is therefore necessary to opt for flexible and porous materials. In general, all natural fiber coatings suppress noise and reduce echoes (wood, earth …).
We advise you to use thermal and sound insulation such as glass, rock wool or cork. Alternatively, opt for synthetic materials such as expanded polystyrene.
Define the different elements to be insulated to improve soundproofing
A soundproofing is usually started whatever the discomfort by the insulation of the door. There will be a tendency to favor doors with a cold cut and which caulk well the doorframe.
For interior doors, hollow core doors, which are often installed by default, should be avoided. We will prefer the doors full or soundproof. It will also be possible to install a threshold of falling door, which makes it possible to close the joint between the inner door and the ground. It is fixed on the bottom of the door.
In a second stage, for the external genes, it will be necessary to isolate the windows. Note that the glazing of your window can be an excellent thermal and sound insulation. This is why triple or double glazing is recommended. Also, remember to close your shutters. They will cut outside noise and insulate the house thermally.
Thick curtains will allow you to absorb echoes.
Then, you can continue the insulation by the ceiling or the floor according to the origin of the nuisances.
Good insulation is achieved by inserting insulation between the joists of the upper floor and the ceiling. This renovation technique is costly but very effective. The parts concerned will not be practicable during the time of the works, to envisage solutions for the furniture and the lodging.
Other less expensive alternatives are available to you. Initially, the installation of acoustic tiles, either stapled or suspended to your current ceiling, is a good alternative. In the case of the suspended ceiling, Your fixtures in your ceiling will become obsolete. It will therefore be necessary to plan the re-installation of your old fixtures on your new false ceiling or the installation of new luminaries.
If you want to soundproof your room by the floor, you can introduce a thicker carpet between your floor and your new floor. There are special soundproofing carpets that come in different shapes (eg tile-specific soundproofing tile). Then your new flooring (floor, tile) can be installed.
Do not forget that the use of carpets makes it possible to reduce easily certain shocks and thus also the noises.
Finally, it is the soundproofing of your walls that will be the simplest . Indeed, The socket boxes and switches must be adjusted according to the coatings on the walls. In addition, you will lose some space.
As electricians rarely leave more wire than necessary, moving the boxes can quickly become problematic.
If you opt for the soundproofing of your walls, different solutions are available to you. The first is to have resilient bars installed on the existing pavement.
The second option is to remove the lining from your wall, insulate from the inside and replace a liner. This solution is more expensive but also more efficient.
Finally, it is important to isolate the ducts. They often transmit different vibrations between floors.
Using an acoustician for optimal soundproofing
In the case of major renovations or consequent parasitic noises, we advise you to call in an acoustician. This professional, specialized in the propagation of sound, is there to establish a diagnosis of the nature of parasitic noises.
It will be able to propose you different solutions tailored according to your expectations and participate in the implementation of the works (choice of materials mainly).
In addition, your interior designer works regularly with acousticians through consulting firms. Do not hesitate to ask his opinion.
