Project Challenge
This major regional airport terminal concourse handles tens of millions of passengers annually, with a high-ceiling open layout and dense passenger flow. Complex mixed noise from passenger conversations, rolling luggage, PA announcements, retail outlets and HVAC systems created heavy reverberation. Public address announcements were often unintelligible, and the noisy environment increased passenger travel fatigue and staff work pressure. As a critical public transportation infrastructure, the upgrade required the highest standards of fire safety, smoke control, sag resistance and long-term low maintenance.
Solution
The entire concourse ceiling was replaced with high-density inorganic fiberglass acoustic ceiling tiles. The material provides inherent Class A fire resistance per ASTM E84 standards with zero flame spread and low smoke emission, fully complying with international aviation building fire safety codes. With an NRC of 0.90–0.95, the interconnected porous structure effectively absorbs complex mixed noise in the high-volume public space. The tiles offer exceptional sag resistance, mold resistance and dimensional stability, maintaining consistent performance in high-airflow, temperature-fluctuating airport environments with minimal ongoing maintenance.
Results
Post-renovation measurements showed a significant reduction in overall background noise across the concourse. PA announcement intelligibility improved dramatically in all seating and walking zones, and passenger surveys reflected a calmer, less stressful travel experience. The durable, low-maintenance ceiling system also reduces long-term facility operation costs for the airport authority. The project meets all modern public infrastructure standards, delivering both acoustic comfort and long-term operational value for a high-volume transportation hub.
