Room Acoustics
Precision control of early reflections, flutter echo suppression, and low-frequency modal balance for performance venues and recording spaces.
Helsinki / Est. 2018
Shaping architectural silence and deliberate resonance.
We design acoustic environments for concert halls, timber libraries, public transit nodes, and quiet listening rooms—treating air, geometry, and surface density as primary structural materials.
