Major aims are to foster close collaborations and build up better synergy in sound and vibration research through a research network including the Hong Kong Polytechnic University, overseas research institutions, public service corporations, local industry and governmental departments; and to assist/influence government noise control policy and to enhance the competitive edges of HK in acoustical products/designs through active technology transfer.
Targeting a leading position in research in relevant areas in the world, the research activities in the Consortium cover the whole spectrum of both fundamental and applied noise and vibration research, e.g., environmental noise, computational acoustics, aeroacoustics, flow-induced vibration and noise, structural vibration, structural health monitoring and damage detection, vibro-acoustics and active control. For convenience, the major research activities in the Consortium can be summarized in an alphabetic manner as
- Active Control of Vibration and Noise
- Building Acoustics
- Computational Acoustics
- Damage Detection and Structural Health Monitoring
- Environmental Noise
- Flow-induced Vibration and Noise
- General Acoustics
During the past few years has made collective efforts to be excellent in research and consultancies, Fruitful achievements have been well recognized by its peers, partially reflected its more than 300 SCI journal publications, more than 50 funds and grants from different governmental agencies, and more than 100 consultancy projects from industry.
The CSVR is established to create and develop a critical mass in the fundamental and applied research in the field of sound and vibration. The specific objectives of CSVR are:
- To carry out high-quality research and development to meet the industrial, commercial and community needs of the society;
- To foster close collaborations and build up better synergy in sound and vibration research through a research network including the Hong Kong Polytechnic University, overseas research institutions, public service corporations, local industry and governmental departments;
- To provide professional services to the government/industry/community in solving problems related to sound, vibration, control, structural integrity and health monitoring through carrying out consulting projects, arrangement of technical workshops and seminars, and development of engineering and scientific devices/systems/strategies;
- To assist/influence government noise control policy and to enhance the competitive edges of HK in acoustical products/designs through active technology transfer;
- To underpin graduate/undergraduate teachings with knowledge created from research and development works.
