Sound reaches beyond the visual frame. It travels through architecture, changes with distance and surrounds the body before we decide to pay attention to it.
That makes sound central to immersive design. It can establish scale, guide attention, connect separate rooms and give visitors a physical sense of presence. This effect comes from precise relationships between sound, space, time and movement, and can be achieved quietly with a modest loudspeaker system.
IMMERSION BEGINS WITH ATTENTION
Immersion is often used as a label for spectacular technology. In practice, it describes a quality of attention: the point at which visitors stop observing an experience from outside and begin to feel situated within it.
Sound can support that shift because it is not confined to the direction of the gaze. A source behind us changes our awareness of the room. A distant event suggests that the experience continues beyond what we can see. A quiet transition can make the next space feel larger without adding another visual cue.
These effects are strongest when sound has a clear role. It may orient visitors, make an object feel present, carry a narrative between rooms or turn participation into an audible consequence. Immersion follows from those relationships, not from the number of effects in the room.
The Austria Pavilion begins with a self-playing grand piano performing a newly composed work in the Viennese classical tradition. Orchestral accompaniment expands the piano into the surrounding space and introduces motifs that return later in the exhibition.
Visitors first meet the music as listeners. The next stage changes that relationship. In an interactive space, up to four people can work with a digital instrument and recombine earlier motifs with electronic sounds. Material that was introduced as a performance becomes something visitors can influence together.
Sound gives this transition its continuity. The musical language remains recognisable while the role of the visitor changes from listening to participating. That shift becomes audible in the way the music responds.
MINESET uses a different approach. The museum route extends for 1.7 kilometres through a former mining complex in Beringen. Across several buildings and rooms, visitors encounter an 18-minute incident from changing acoustic perspectives.
Machinery, water, radio transmissions, voices and alarms give each space a distinct function within the story. Some events are heard directly; others arrive through a doorway or from a room that visitors have not yet reached. Architecture determines how the narrative is revealed.
The soundscape develops from everyday operation towards emergency. Because the same incident continues across the route, distance and movement become part of the dramaturgy. Visitors do not receive the story from one fixed listening position. They assemble it while moving through the site.
Here, immersion comes from consistency between sound and place. The industrial architecture supports the recordings, while the spatial score keeps the changing viewpoints connected. The result is detailed and physical without requiring every moment to be loud.
WHAT IMMERSIVE DESIGN REQUIRES
The two projects use sound differently. The Austria Pavilion builds immersion through music, recurrence and participation. MINESET uses spatial continuity and realistic detail to place visitors inside a developing narrative.
Both depend on the same design principles:
- Sound has a defined role within the visitor journey.
- Architecture and playback are planned together.
- Transitions connect one listening condition to the next.
- Interaction changes the experience only where the response has meaning.
- Quietness and distance are treated as compositional material.
Immersive sound design therefore begins before final audio production. It belongs in conversations about architecture, scenography, media, visitor flow and technical infrastructure. Decisions about thresholds, materials and loudspeaker positions already shape what can be heard.
This early integration is the work of sound scenography. It connects composition, spatial audio, acoustic conditions, interaction and sonic dramaturgy across the whole experience.
Spatial audio helps place and move sound. Interactive sound makes actions audible. A spatial score maps when and where events appear. Sonic dramaturgy defines how attention develops from arrival to departure. Together, these practices make immersion a designed relationship between visitors and the space around them.
This approach guides our work on immersive sound for exhibitions, museums and installations, from early spatial planning to composition, system integration and on-site tuning.
