The group “Absorbent layers” has been added to the program library. This way, users can include 2D absorption elements in the project model. These, as occurs with furniture, are not taken into account in the sound insulation calculations and only affect the prediction of the reverberation level inside the space in which they are installed.
Since the types of absorbent layers are characterised by their sound absorption coefficient (α), they must be associated with the internal or external side of the partition.
