Driven by the upsurge of global urban rail transit and airport hub construction, the acoustic environment of large passenger flow public spaces such as waiting halls and transfer stations has received increasing attention. High ceilings, hard floors and a large number of reflective surfaces lead to long reverberation time and poor broadcast clarity in transportation hubs, which affects passenger experience and operational efficiency. Acoustic design is gradually being included in the standard design specifications of transportation buildings.
Industry monitoring data shows that in the first half of 2026, acoustic projects in public areas of global transportation hubs increased by 25% year-on-year. High-density inorganic fiberglass acoustic ceiling tiles from the Ceiling Series (NRC 0.90–0.95) are fully applied in public areas, which efficiently control overall ambient reverberation in large spaces, and have excellent sag resistance and aging resistance, adapting to long-term operation of high-flow public places. Partial perforated acoustic panels with mineral wool backing are arranged on the walls to optimize mid-low frequency resonance and further improve the clarity of public broadcasts.
All QinSound transportation building acoustic solutions carry ASTM E84 / EN 13501 Class A fire certification, meeting the safety requirements of large public gathering places. Industry analysts predict that with continuous investment in transportation infrastructure, acoustic systems will become a standard configuration for the construction of transportation hubs.
