A summary document has been created containing the results of the global acoustic indices obtained for each space, together with the limit values established by users. Similarly, users can configure the elements to be displayed and only show spaces that do not meet all the requirements or values obtained for each separator or connection.
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.
The following examples have been added:
As of the 2017.k version, AcoubatBIM by CYPE allows users to introduce external claddings for the roof and façade types, as was done in previous versions for partitions and floor slabs. Thanks to this implementation, ETICS insulation systems can now be introduced in the construction solutions used in the building.
AcoubatBIM by CYPE is a tool developed by CYPE and the CSTB (Scientific and Technical Centre for Building) with the aim to help users study the insulation and acoustic conditioning of buildings. It calculates the indices that evaluate the insulation of airborne noise (indoor and outdoor), impact noise insulation and the reverberation level in indoor spaces, in accordance with the procedure contained in the EN ISO 12354:2017 code.
This application is integrated in the Open BIM workflows using the IFC standard.
The first version of AcoubatBIM by CYPE is included in the installation of CYPE programs in French and English. It will be implemented in more languages in upcoming versions.
