Sainte-Anne Multipurpose Concert Hall

Tisseyre + Associés has 40 years of experience in the acoustics of performance halls, its core business originally. 30 years ago, anticipating the digital revolution and 3D visualization, we developed a tool for 3D models of performance halls: Hall Acoustics^®. 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 performance hall are structuring for its architecture, we have developed a joint working methodology with the architect.

Complete room acoustic mission – “all-reflective” solution

Thanks to our 3D model tool, Hall Acoustics^®, we can collaborate from the design phase with the architect in order to integrate the acoustic performance of the room into the architecture. Our work therefore does not focus on the dimensioning of a posteriori solutions of acoustic absorbers to attenuate the effects of reverberations. We work with the architect on the choice of shapes and materials used in order to optimize the reverberations so that they contribute to the acoustic performance of the room, which can be summarized as:

• Sound strength, clarity and definition. The sound should be loud, clear and precise.
• The sound envelopment of all spectators. The people in the room feel like they are part of the show: the sound envelops them.

Tailor-made acoustic solutions

The integration of acoustic performance in the performance hall has led us to offer tailor-made solutions for the ceiling, the walls and the reflective mobile panels.

• The shaping of the ceiling was designed in such a way that its reflexivity allows the sound to be distributed evenly in the space;
• The choice of materials as well as the shapes of the walls and the movable reflective panels have been sized so that they can adapt to the versatile use of both contemporary and classic shows.

The sound reflection lobes were calculated when designing the acoustic wood panels of the room so that they contribute to the acoustic performance of the room for each use.
