As part of the construction of the Pau conservatory, this former 19th century chapelth century has been rehabilitated to become an auditorium with optimal acoustic performance. Attached to the music school, this new auditorium had to be able to host concerts of symphonic and liturgical music, while not distorting the original architecture.
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 acoustic mission
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:
The significant initial reverberations of the place, specific to its initial use, made it unsuitable for hosting symphony or chamber orchestras.
Tailor-made acoustic solutions
Instead of looking for a reduction in sound volume, we worked on materials and shapes to reduce reverberation time by rebalancing reflections. For this, and with the aim of offering a reversible treatment, we have dimensioned thanks to Hall Acoustics® acoustic fabric solutions and various wall panels. We also sized and participated in the choice of furniture (stage area and seats) so that it contributes to the acoustic performance of the room.
