This research team focuses on advancing technology in enhancing the acoustic and vibration control in the built environment. Topics concerned include the application of active noise control, development of assessment methodology, noise prediction and control in flow ducts, air-borne and structure-borne sound transmission within residential estates and within buildings, acoustical environment performance, mobility studies, speech intelligibility in schools, architectural acoustics and signal diagnostics.

Efforts have also been made on the development of commercial usable products. A low pressure loss broadband compact duct flow silencer is in the design stage. Also, research works concerning vibration transmission within buildings will lead to the development of a realistic statistical energy model for use in new building design. In addition, it is planned to develop an active controller for transient noises. The research team also gives advices to the industry in forms of brief communications and/or PolyU consultancy projects. The topics / issues cover nearly all branches of applied acoustics and are not restricted to those described above.

The team is prepared to build a multipurpose acoustic testing facility of international quality. Industrial donation and collaboration are involved in its building.
