Project Context & Acoustic Challenge

Hotel ballrooms and expansive event venues feature massive spatial volumes and hard structural surfaces, which inherently generate long reverberation times and muddy sound reinforcement. High-occupancy banquets, conferences, and amplified speeches suffer from harsh slap echo and low speech intelligibility, while conventional flat acoustic panels fail to complement the vibrant, high-end interior aesthetics required in modern hospitality spaces.

Engineered Solution & Design

To achieve superior sound absorption while creating an engaging visual landmark, the ballroom walls were clad in custom carved PET acoustic wall panels featuring a dynamic dual-tone perforated dot array. Precision CNC-routed circular cutouts expose a striking orange and white background substrate, transforming acoustic treatment into an artistic feature wall. Installed as a continuous vertical array behind guest lounge seating, the pattern effectively breaks up planar sound reflection paths across large wall elevations.

Performance & Compliance

Engineered from high-density, eco-friendly PET polyester fiber, the perforated panel matrix achieves an upgraded NRC 0.85 noise reduction rating to dampen mid-to-high frequency vocal reflections and acoustic echo. Multi-axis CNC routing ensures razor-sharp, burr-free perforation edges that resist fraying or distortion over wide surface areas. Certified for strict ASTM E84 Class A fire-retardant safety and low-VOC indoor air emissions, the light-fast panels provide exceptional durability and acoustic comfort for demanding hospitality operations.
