Wieden+Kennedy is a groundbreaking advertising agency with offices worldwide. The conference rooms of its Amsterdam office were plagued with poor acoustics, caused by their high ceilings and glass walls.

As part of a comprehensive plan to improve acoustics, two Round&Round 120XL luminaires were installed from the ceiling, totalling 22 square meters (237 square feet) of acoustic foam. Resulting from this large surface of sound absorbing material, reverberation time was brought down from over 1.3 seconds to 0.7 seconds, enabling the Amsterdam staff to have clear video conferences with colleagues in for instance Shanghai or São Paulo.
