Auditorium La Scène, Millennium, Crissier
La Scène, a 500-seat auditorium in the Millennium Crissier complex, is equipped with state-of-the-art audio and video technology. Kahle Acoustics has been tasked with improving the venue's acoustics so that it can host classical music concerts. The goal — both on stage for the musicians and in the audience for the public — is achieved through solutions that combine the optimization of natural acoustics with an electroacoustic system.

Above the 120 m² stage of the 500-seat auditorium, two rows of acoustic reflectors tilted and curved installed for bettering sound projection towards the audience, sound feedback for the musicians on stage and for offering early acoustic reflections to better the stage performance.

Professor Kahle and his viola are testing the response of the curved acoustic reflectors suspended above the stage to assess how sound is reflected and propagated on stage and throughout the auditorium. These tests help determine the optimal heights and angles of inclination for all the reflectors installed on stage. Photo © Kahle Acoustics
The tilt angles of the suspended reflectors are adjusted following testing, using a suspension system consisting of a rope on each side of the panel, suspended from a single point on the existing truss structures, which facilitates installation and removal. Photo © Kahle Acoustics
Lateral view of the stage and its wooden acoustic reflectors (stage-left). The loudspeakers used to incorporate an artificial reverb system and enhance the acoustic feedback from the auditorium to the stage are concealed within a fabric lining in the walls of the auditorium; the microphones are partly integrated above the stage and partly into the ceiling of the auditorium.
