Year

Delivered in 2002

In 2002, this mixed room which hosted concerts and conferences was rehabilitated to give it optimal acoustics suitable for hosting concerts. It previously had an internal electroacoustic system suitable for use in conferences but unsuitable for concerts.

Methodology

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.

Tasks

Complete room acoustic mission – “all-reflective” solution

Thanks to our 3D modeling 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

Thanks to Hall Acoustics®, we have developed acoustic solutions of vertical and inclined panels. Their composition as well as their inclination have been calculated so that they participate in an optimal response of the acoustics of the room.

In addition, we participated in the custom design of the chairs. Thus, the armchairs modified with acoustic raisers incorporate acoustic reflectors. This enhancement promotes early reflections and thus contributes to increasing the loudness of the room.
