Project Background
A regional transport hub launched full ceiling renovation for its main departure lounge to resolve long-standing noise pollution issues. The original mineral fiber ceiling possessed weak sound absorption capacity. High passenger flow generates overlapping chatter, luggage rolling friction noise and repetitive public announcement echoes. As a high-density public transit venue, the space enforces strict requirements for ceiling material Class A fire safety, humidity resistance and long-term dimensional stability under large-span air-conditioned environments.
Solution
Complete full-area replacement with inorganic high-density fiberglass acoustic ceiling panels was carried out across the entire departure waiting zone. Inherent Class A zero-flame-spread, low-smoke performance complies with international public transport construction fire safety codes. Interconnected porous substrate delivers an NRC of 0.90–0.95 to absorb crowd chatter, luggage rolling sound and mechanical ventilation background noise. The material resists sagging, mildew and permanent deformation under circulating air and fluctuating humidity, compatible with standard exposed grid ceiling systems for seamless integration with lighting, air vents and fire sprinkler facilities.
Final Outcome
Ambient noise levels during passenger peak hours inside the departure lounge decreased substantially. Public broadcast audio became clear with no echo interference, helping passengers easily receive service information. The durable, low-maintenance ceiling system cuts annual facility maintenance expenditure for the hub management department.
