Introduction
The Aerodynamics and Acoustics Facility (AAF), was formerly named the CLP Power Wind/Wave Tunnel Facility (WWTF). The facility is one of central research facilities at the Hong Kong University of Science and Technology (HKUST). The facility was first opened by the Hon. Tung Chee Hwa, Chief Executive of Hong Kong SAR, the Chancellor of HKUST, and the Hon. Michael D. Kadoorie, Chairman of CLP Holdings, on the 9th of June, 2000. Between 2015 and 2019, the facility was redeveloped with a brand new state-of-the-art low-noise wind tunnel, and world-class large acoustic testing laboratories, focused towards to a new era of modern and exciting aerodynamics and acoustics research and development.

Prof. Xin Zhang welcomed Ms Lillian Cheong, Under Secretary for Innovation, Technology and Industry Bureau, to the facility on Friday.
During the visit, Ms Cheong toured HKUST's Aerodynamics and Acoustics Facility (AAF), accompanied by Prof. Zhang and Prof. Tim Cheng. Ms Cheong was introduced the current research projects and the capabilities of the facilities.
The visit provided an opportunity to introduce HKUST’s research strengths and explore potential avenues for collaboration with Hong Kong’s Innovation, Technology and Industry Bureau.
HKUST AAF welcomed Prof. Larry Li’s students for a MECH3640 laboratory class. The session introduced the large and small wind tunnels, as well as the acoustics chambers. Students also took a guided tour of the facilities and received an overview of their capabilities.
We were pleased to support the course and give students the opportunity to connect wind-tunnel and acoustics theory with practical laboratory demonstrations.
HKUST AAF welcomed Prof. Xin Zhang's students for MECH5981 lab class. The session introduced two key acoustics spaces: the reverberation chamber and the anechoic chamber.
In the reverberation chamber, students explored how sound reflections and room modes affect measurements. Demonstrations of microphone movement and reverberation-time testing showed how acousticians assess sound decay and use room measurements in sound-power and sound-absorption evaluations.
The class also visited the anechoic chamber, where sound-absorbing wedges help create a controlled free-field environment. Students learned how the chamber is designed and verified, and how sound levels change with distance from a source. The visit highlighted why sound-pressure measurements at multiple positions are important when estimating a source’s sound power.
We were pleased to support the professor’s teaching and give students the opportunity to connect acoustics theory with practical laboratory demonstrations.
