José Cabanis media library

Tisseyre + Associés has 30 years of experience in 3D modeling of acoustic phenomena in rooms in operation and the acoustic performance of materials. Instead of using the sound ray shooting technique which does not take into account the architectural details, we use the finite element mesh technique which allows these details to be modeled with finesse in order to fully integrate them into the acoustic performance. of the room from its conception. Based on the observation that the acoustics of a room are structuring for its architecture, we have developed a joint working methodology with the architect.

Complete acoustic mission

Our tool for digital models of workspaces in operation, Intelligibility®, constitutes a work support allowing us to offer tailor-made solutions according to needs. These 3D models fill in the gaps of sound measurements which are only acoustic photographs. They thus make it possible to anticipate acoustic solutions according to the multiplicity of uses in order to integrate them into the architecture.

Sound insulation and dry dies

The José Cabanis media library is based on a wooden structure. Consequently, the soundproofing of the place represented an important issue with regard to the polluted sound environment in which it is located (nearby transport route). Thanks to our virtual acoustic laboratory we were able to verify the acoustic performance of the wood materials used. The virtual acoustic laboratory has enabled us in particular to ensure:

• Controlling the acoustic performance of walls equipped with stiffeners
• Taking into account, in the laboratory test reports, the site realities of the assembly details of these structures, determining their acoustic performance.
• The integration of mechanical effects under stress or related to the effects of expansion of wooden planks. Thus we were able to predict and solve the potential problems of airtightness (and therefore acoustic) of the walls.
