The expansion of Phu Quoc International Airport is part of a broader infrastructure programme preparing the island for the APEC 2027 summit and supporting its long-term ambition as a leading international destination. Developed for Sun Group and Sun Airport Corporation, the project includes a new Terminal T2, a VIP terminal of approximately 6,000 sqm, additional aircraft stands and major runway infrastructure, with a long-term capacity target of up to 50 million passengers per year by 2050. The architectural teams were led by CPG Consultants, with interior design by AEDAS and HOK.
Addressing airport noise control across spaces of this scale required careful coordination from the earliest stages of design. Large open halls, waiting areas, circulation corridors and VIP lounges each carry distinct acoustic expectations while remaining connected within the same passenger journey. The combination of high ceilings, reflective architectural finishes and constant passenger movement naturally drives reverberation upward and raises background noise levels, making speech intelligibility for public announcement systems a critical performance requirement. Finding the right balance between the architectural openness of the terminal and the acoustic design standards expected of a next-generation international airport was one of the defining challenges of the project.
We were appointed to support the acoustic strategy for the future terminal and passenger areas of the airport, working in close coordination with the architectural, MEP and AV teams throughout the design development.
Our work focused on passenger acoustic comfort, reverberation control and speech intelligibility studies for public announcement systems across the main terminal spaces. Particular attention was given to large circulation and waiting areas where noise build-up and extended reverberation times could affect both passenger comfort and communication clarity. We provided recommendations on architectural shapes at early stages and then for ceiling systems, finishing materials and acoustic treatments adapted to the operational constraints of the airport environment while remaining consistent with the architectural concept developed by CPG Consultants, AEDASand HOK. Throughout the project, the objective was to support a smoother and more comfortable passenger experience by integrating noise reduction requirements into the design rather than addressing them separately from the wider architectural and operational ambitions of the terminal.
Our acoustic studies supported the development of a more comfortable and intelligible passenger environment across the future airport facilities. By addressing reverberation control and speech clarity in the main public areas, the project was positioned to deliver clearer announcements, better comfort in waiting zones and a more balanced acoustic atmosphere despite the scale and activity of the terminal spaces. The acoustic strategy also contributed to improving the experience within the VIP terminal, supporting the premium standards expected from an international facility of this significance.
Through continuous coordination with the wider design teams, noise control requirements were integrated into the project from early design stages, helping maintain consistency between passenger comfort, architectural intent and airport operations. The project forms part of Phu Quoc’s broader infrastructure development ahead of APEC 2027, where acoustic quality contributes directly to the international standing of the island as a destination.
