Marc
DebièsSound Scenographer & Designer

Sound is an invisible architecture.
I transform the acoustic wave into a sensory experience — from complex large-scale flows to palace hotels, from luxury to art.

Users and customers live more intense, more memorable moments — and come back.

Marc Debiès — Scénographe & Designer Sonore

Marc Debiès

Sound is a fundamental issue, not a finishing touch.

I am a sound scenographer and sound designer, founder of hého design — the pioneering agency in spatial sound design that I founded and led for close to 20 years. Now working independently, I create new sensory experiences of space and time, coordinating when needed a network of long-standing talents and partners.

I translate the emotional and physical potential of sound into concrete and strategic experiences — reconciling sensory ambitions and real-world constraints. I orchestrate sonic journeys and soundscapes that bring life, coherence and resonance to spaces — to soothe, guide or make vibrate. Always at the service of those who live in them.

Bringing sound in from the design stage makes it a signature — the one you remember without knowing why.

What drives me is understanding, imagining, experimenting, creating: opening up new sensory territories, anticipating the uses of tomorrow, exploring possibilities to enrich everyday life.

Complex projects, multidisciplinary teams, deadlines met.

"Working with Marc Debiès profoundly renewed our approach to sound. Together, we designed a sonic journey starting from auditory perception and users' felt experience. By taking psychoacoustics into account, we were able to create work environments that are clearer, calmer and more inclusive."

Working together

A project often starts with an intuition — before the budget, before the brief.

To move forward without immediate commitment, I offer an immersion mission — one or two days to map the sonic challenges of your project, identify risks and opportunities, and outline first creative lines of thinking. A concrete deliverable, a controlled investment.

It all starts with a conversation!
