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:

1. To carry out high-quality research and development to meet the industrial, commercial and community needs of the society;
2. 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;
3. 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;
4. To assist/influence government noise control policy and to enhance the competitive edges of HK in acoustical products/designs through active technology transfer;
5. To underpin graduate/undergraduate teachings with knowledge created from research and development works.
