Acoustic qualities

A new approach regarding acoustics of your spaces

Control of a building’s sound quality is obtained by the balance between absorption, diffusion and reflection of the sound. Tectonique 5.5 ceilings, due to their shapes and relief forms, directly influence these three acoustic characteristics. The choice of a model will therefore be made according to its relief and openings, taking into consideration the layout of the space and the acoustic effect being sought.


Sound absorption is the ability of a wall to partially absorb a sound wave and only to return a part of the energy received to the point of departure. This property thus helps reducing reverberation in a space and increases the acoustic comfort and the intelligibility of speech.

The sound absorption of Tectonique 5.5 ceilings, is created by the position of the tiles and the spaces between them and by the characteristics of the material.


Reflection is a physical phenomenon by which a surface returns a portion of the sound waves. It is the type of surface and the nature of the material which affect the reflection of a sound wave.

The surface of Tectonique 5.5 tiles contributes to controlling sound reverberation. A part of the wave is reflected whereas the other part enters the material.


When a sound wave encounters a flat obstacle, the angle of reflection is equal to the angle of incidence, same as a mirror. If the surface has relief forms and shapes, the obstacle becomes a point of dissemination and the sound wave is sent back in all directions.

The relief forms and the changes of planes of Tectonique 5.5 ceilings create this dissemination and limit the areas of focus of the sound and echoes. This more diffuse and homogeneous acoustic enriches the sound balance of the space.

The evaluation of these three acoustic characteristics is provided in the data sheets for each model. These give guidance in aimed at comparing the potential of acoustic correction of one model in relation to another.
