1. Physical principles involved in absorption mechanisms
Absorption is the phenomenon resulting from the dissipation of sound waves. This dissipation can occur either when the wave comes into contact with a wall or obstacle, or during propagation.
The acoustic quality of a room depends to a large extent on the characteristics of the reverberant field (level, duration, homogeneity, etc.). Controlling this quality therefore involves controlling all the parameters likely to modify absorption, particularly those of the materials making up the room walls.
1.1 General principles governing wall absorption mechanisms
The aim of this section is to show how materials act according to their physical properties.
To better explain the phenomena involved, we'll simplify them by...
