Or sound insulation: which aims to avoid the propagation of noise. The noises being of two natures: solidiens thus in the form of vibrations of the elements of construction or aerial ie the noises which propagate directly in the air.

Acoustic insulation such as glass wool, Rockwool, hemp wool or cellulose liana is used as absorbers or “dampers” in a mass-spring-mass system, allowing good sound insulation. High-performance sound insulation consists of separating the sound dubbing from the existing walls of a room. The separation is done by isolating the ceiling, walls and the floor and doors of the room to be treated. There must be no rigid contact between the existing walls and acoustic dubbing.

Technically, to achieve effective sound insulation, the implementation must be done respecting the principle mass/spring/ mass. Two masses are separated by a spring, usually a blade of air and a mineral insulator. Between the two masses, the spring attenuates the energy of the sound and serves as a buffer to the system. On arrival in the second mass, the noise is considerably reduced because it has lost energy.

The thickness of acoustic ceiling and acoustic qualities of the insulation used (glass wool, Rockwool, hemp wool, cellulose wadding, etc. cf: an article which insulation to choose? ) Are extremely important in optimizing the acoustic performance of the insulation. system. Choosing the right sound insulation allows sound insulation systems to achieve greater performance.
