The acoustic firm Tisseyre + Associés has developed a joint working methodology with the architect. For 40 years we have been working with digital 3D modeling tools to model the soundscapes of different spaces. These tools and methodologies are essential working aids for close collaboration with architects and urban planners at all stages of the project. By anticipating, optimizing and integrating acoustic solutions within architecture and urban planning, we build coherent sound spaces according to uses and needs.

Solutions to urban acoustic pollution

In this polluted sound environment, we have optimized acoustic insulation solutions thanks to BIMAE^®. This tool and method for 4D (temporal 3D) modeling of soundscapes in the future state of completion takes into account the noises of transport routes and those of human activities hour by hour from the design phase.

Solutions to vibrations related to railway tracks

Thanks to our R&D, we have developed unique technical solutions in protection against vibrations: structural impedance breakdown. The acoustic trenches provide a buffer between the vibration emission zone and the receiver. This innovation not only reduces work time but also costs (around 1 million euros here).

Acoustics of work spaces

We have developed fixed and mobile partitions using our tool for digital models of open spaces in operation, Intelligibility^®. Real support for joint work with the architect, these models make it possible to anticipate acoustic solutions according to the needs of users in order to integrate them into the architecture. An open space must meet mainly 3 criteria in terms of acoustics:

• Easy communication between employees, it must be intelligible
• Concentration on intellectual tasks, the ambient noise level must be controlled
• Acoustic discretion between the teams, the different activities must be isolated.

All these factors being co-dependent, it is essential to anticipate them in order to ensure the acoustic quality of a workspace.
