Théâtre de Beaulieu

Originally opened in 1954, the Théâtre de Beaulieu remains to this date the largest in Switzerland. Its renovation and upgrade include the design of a new acoustically optimised orchestra shell and the integration of an electronic reverberation system to enhance natural acoustic reverberation. The Théâtre hosts miscellaneous shows ranging from contemporary dance, drama, classical concerts, including those with the Orchestre de la Suisse Romande and with the Orchestre de Chambre de Lausanne, to jazz and pop concerts. This renovation grants the Théâtre with a great acoustic versatility and ensures an excellent quality for all uses.

Théâtre de BeaulieuThe stage of the Théâtre de Beaulieu was equipped with a new modular orchestra shell allowing classical concerts to be held with excellent listening conditions on stage. The sidewalls and the ceiling of the shell are cladded with curved wooden panels, while a semi-reflective fabric closes off the rear of the stage, allowing for lighting effects or video-projection.

The new ceiling follows a complex curved shape, which was precisely optimized for the most homogeneous acoustic experience achievable. In particular, concave ceiling areas were carefully checked and adjusted to avoid excessive acoustic focussing. Foto © Kahle Acoustics
