07 / Installation · Open Project
An adaptive light environment that translates crowd sound dynamics into luminous feedback — a living mirror of collective behavior.
Concept
This installation creates an immersive light environment that responds in real-time to the acoustic presence of people in a space. Distributed sound sensors translate the volume and spatial dis[...]
As visitors move through the space, their collective vocal energy — conversations, laughter, shouts, silence — becomes visible as shifting zones of brightness. Periodically and without anno[...]
The installation asks: at what point does a group of individuals become a collective entity? When does crowd behavior emerge as something beyond the sum of its parts?
Technical Approach
| Sensing | Distributed microphone array — electret or condenser mics feeding an Arduino or Raspberry Pi for sound level detection and basic spatial mapping |
| Processing | Microcontroller translates audio data into lighting control signals. Volume → brightness at MVP. Pitch → colour at scale. Inversion logic runs on a randomized timer to prevent predicta[...] |
| Lighting | DMX-controlled LED array — PAR cans, floods, or panels depending on venue and budget. Dimmer packs or smart controllers |
| Space | Rectangular corridor or room, minimum 20′ × 40′, 10–12ft ceilings. Flow-through design (separate entry/exit) to prevent bottlenecking. Dimmable ambient pr[...] |
| Power | 240V for stage lighting (6–8kW draw), standard 120V for control systems. Relay switching for higher-load instruments |
| Stack | Arduino / Raspberry Pi → audio interface → DMX controller → lighting fixtures. Code repository open below |
