The walls are a very important element when it comes to the soundproofing of a building.

The transmission of sound through the wall depends on many factors such as:

  • Mass of the wall;
  • Angle of incidence of sound waves;
  • Porosity of the wall;
  • Stiffness of the wall.

The soundproofing of a wall (between the sender and receiver location) will consequently not only increase the insulation of the wall under intervention, but also increase the result of the acoustic insulation of the adjoining ceiling, reinforcing the soundproofing of the adjacent places.

This increase may be due to the elimination of acoustic bridges, resulting from the union of the acoustic insulation of the ceiling with the original wall.

It is for this reason that, when dimensioning a room’s sound insulation, we always have to take into account the walls.
