Thanks to the soundproofing of walls and ceilings, we can achieve the desired peace. To eliminate or reduce the noise coming from adjacent rooms through the wall, we must reduce vibrations, plug sound leaks and absorb ambient sound to bounce off walls and rigid surfaces.
Sound is transmitted when vibrations move through the air, floors, ceilings, and walls. Sound waves travel from one room to another or from the outside of the house to the inside. What solutions are there to isolate a space from these noises?
To soundproof a wall, the first thing to do is to be clear about where the noise is coming from, that is to say, the cause that generates it. This allows us to attack the weak point of our house where the annoying noise is entering.
The noises can be aerial, propagated by the air, music, voices, etc. They also impact those produced by the collision of objects; structural, those transmitted through the building’s structure, impulsive noises that stand out to constant intervals of time.
If we suffer noises of one type or another, we will need to soundproof walls, ceilings, floors, etc.
Airborne noise is transmitted only through the air, and these sound waves have medium to high frequencies. Impact noise sound waves have low frequencies and can easily pass through walls, windows, and doors. Another name generally used for this type of noise is structure-borne noise.
This is very important because materials block only the first type of noise in your walls—for example, acoustic foam panels.
Soundproofing consists of using a barrier of some kind to prevent sound from entering a space. And we have two ways of doing this: by sound absorption and by noise reduction. There are several approaches to both noise reduction and noise absorption and a variety of materials to use for each purpose.
Noise reduction can be achieved by using the space between rooms. The more space sound waves have to dissipate, the better. And if the distance between the source of the noise and the area to be soundproofed is increased, the noise entering the space will be reduced.
The other method is noise absorption, also known as damping. With this method, the energy of the sound wave is converted into heat within the insulation. This increases energy efficiency while reducing sound. what are sound walls? sound walls also suppress echoes and reverberation.
Sound insulators are materials that work to reduce noise entering a room from outside the house or from other rooms.
Regulatory requirements for impact and airborne sound insulation will influence the design of interior partition elements and facades, roofs, party walls, and floors in contact with the outside air.
The acoustic insulation material can be installed during construction or later as part of a home improvement project. In such a case, blown-in products, such as foams, are easier to install in existing homes.
You can repair insufficiently insulated areas yourself or use a professional to do the job. Installing most of these materials is a relatively easy do-it-yourself project for any skilled handyman.
A high thermal-sound walls insulation level can be achieved by installing 14 cm thick wood fiber or recycled cellulose wall, floor, and ceiling panels.
