L’Écho des pierres is an immersive sound installation—a device that reveals the acoustic life of a space and offers a singular sensory experience.
Four rotating ultra-directional loudspeakers emit sound waves that bounce off the walls, bodies,
and every object present in the environment. As visitors move through the space, they can physically sense the relationship between sound and architecture.
Through directional-speaker technology, the audio signal is modulated into ultrasound.
It becomes audible only when it meets a body or encounters the architecture of the space.
Through this interplay of directivity and rotational movement, one can distinctly hear how the architecture filters sound—its dimensions, shapes, materials, and surfaces becoming active agents in the listening experience.
The composition is structured as a writing of sounds and movements for four
modules—loudspeakers and motors. Each section articulates a particular relationship between sound and motion.
The first part is built from violin recordings: each loudspeaker plays a single note, and together these notes form chords that invite the visitor into the music, allowing them to perceive the intervals
and harmonic tensions between tones.
The second part explores the spectral territory of white noise—a rich, continuous field that shifts our perception of the space as the motor speeds modulate.
The third part introduces a more rhythmic development, making the architecture itself resonate through patterns of movement and silence.
The fourth is more pointillistic, composed from sounds of glass and bouncing materials, creating a constellation of fleeting sonic events.
These four phases span a wide spectrum of auditory perception and activate psychoacoustic effects born from the dynamic relationship between the visitor and the surrounding architecture.
Conceived as an instrument for listening to—and revealing—the acoustic body of a space, the installation can adapt to large resonant environments.
The first exhibition, following an artist residency, took place in the Church of Champaubert.
Composition: 25-minute loop

This work has been presented in a series of remarkable architectural settings: the church of Champaubert on the shores of Lac du Der; Saint Nicholas Church in Tournai; Institut Saint-Louis in Namur as part of KIKK Festival; and the Sépulcre in Caen for the ]Interstice[ Festival.
