About — Studio
A quiet practice in sound.
SOUEND is an acoustic systems studio working at the intersection of material science and architectural design. We build measurable silence into the spaces where it matters most.
Practice
We collaborate with architects, interior designers and acoustic consultants to translate technical performance into architectural form. Each system is engineered to ISO 354 and tested for the entire 125 Hz – 8 kHz band.
Our partnership with CELLOFOAM — Germany's leading manufacturer of acoustic foam systems — gives every product a scientific foundation. Polyester, polyurethane and melamine cores are layered to deliver broadband absorption without sacrificing the calm of a finished space.
