What Noise Reduction Coefficient (NRC) is required for indoor pickleball warehouse ceilings?

Commercial indoor clubs require acoustic materials with an NRC of 0.85 or higher to prevent deafening echo build-ups across multi-court play.

The detail

Unmitigated steel warehouse buildings have hard concrete floors and corrugated metal roofs with an NRC of 0.05, reflecting 95% of acoustic energy. When 8 to 16 courts operate simultaneously, reverberation time (RT60) can exceed 4.5 seconds, creating a chaotic 85+ dBA wall of sound that hinders communication and causes auditory fatigue. By suspending flame-retardant melamine foam baffles or fiberglass acoustic clouds with an NRC of 0.85 to 1.05 across 40% of the ceiling area, reverberation time drops below 1.5 seconds, dramatically lowering the overall ambient sound floor.
