Scientific concert by the Ophonius group
For the past four years, the Laboratoire Centre Lyonnais d'Acoustique (LabEx CeLyA) at the University of Lyon, in collaboration with the Groupe Ophonius, has been offering scientific concerts for local secondary school students.
This group, created some 25 years ago and made up of 3 professional musicians and 2 musicians/teacher-researchers from the Université du Maine (Le Mans), offers "scientific concerts" for the general public.
The group's original music, somewhere between jazz and world music, takes the listener by the hand to explore his or her own perception of the world of sound.
The "scientific concerts" show invites listeners to discover the physical phenomena that generate this perception, to quantify it, to protect themselves from it when it becomes unpleasant, or to shape matter to make it pleasant.
Technically speaking, this show presents the physical phenomena of acoustics, relying initially on the spectator's own perception.
The physical phenomena behind this perception are then analyzed using live experiments and multimedia supports (photos, videos, animations) commented on by the acoustics teacher-researchers and supported by the group's original soundscapes and music.

How do your ear and brain perceive sound? How do you locate a sound source in space? How can you hear with just one ear?
- The concert on Thursday 20 February 2025 at 6.18 pm is open to all. To register, click here: théâtre Astrée
- The concert on Friday 21 February 2025 at 10.00 am is for local secondary school students in science classes.
These concerts (lasting 1h30) are FREE but registration is required subject to availability.
Venue: Théâtre Astrée, 6 avenue Gaston Berger, 1st floor, Campus La Doua, Villeurbanne. Access

IMMERSONS
How do your ear and brain perceive sound? How do you locate a sound source in space? How can you hear with just one ear?
To answer these questions, the OPHONIUS quintet, celebrating its 25th anniversary this year, invites you into a three-dimensional sound space in a show combining music, experiments, illustrations and perceptive phenomena.
Enter the world of sound perception and discover how the human ear perceives sound.
