This former hospital has been rehabilitated into a multidisciplinary complex in the town of Neuilly-sur-Seine. It includes: a 700-seat auditorium; a music conservatory with ten rehearsal studios; an exhibition hall and multidisciplinary activity rooms.
Methodology
30 years ago, anticipating the digital revolution and 3D visualization, Tisseyre + Associés developed a tool for 3D models of rooms: 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.
Tasks
Complete acoustic mission
Uses being structuring for the acoustics of a place, we are interested in the needs of music conservatories. As these are places where music is taught, the acoustics of the place must meet two main criteria:
Accurately report on a student's playing to facilitate a teacher's critical analysis without the reverberation of the place being excessively rewarding for his playing.
A homogeneous acoustic response from the room: for optimal group music learning, each student must have acoustic feedback from their own playing and perfect listening to others, regardless of their position in the room.
To respond to this, we integrate acoustic solutions into the architecture, whether in the choice of volumes, materials or even in the shape of moldings.
Bespoke architectural acoustic solutions
First of all, given the low volumes, it is important to integrate some absorbent materials in order to adjust the acoustic reverberation to a sufficiently low value.
In addition, in order to guarantee the homogeneity of the acoustic responses of the classrooms, we have developed a panel based on a wooden claustra with the industrialist Laudescher, adaptable to measure according to the contexts. Thanks to our 3D modeling tools, we model the shapes of the reflection waves (low, medium and high frequency) on the panel and thus adapt the design to provide an optimal acoustic response to each classroom.
