Center for sound and vibration research

Due to a more acute demands in the research for acoustics and vibration, the Center for Sound and Vibration Research (CSVR) was established in 2000. The main facilities of this center encompass anechoic chamber, reverberation chamber, MTS dynamic test lab, vibration lab.



There are 5 professors and more than 20 master and doctoral students engaged in this center. The main research areas of CSVR include:

  1. Noise generation mechanism and its control: tire pitch pattern design, noise source from machinery, noise source identification in buildings;
  2. Phycical model for noise and Vibration: underwater acoustics, structural acoustics, aero-acoustics, fluid-structure coupling vibration;
  3. Vibration and noise control: design of noise barrier, active control of noise, vibration insulation design, test for sound absorptive material, test for sound insulation material;
  4. Propagation model for noise and vibration: statistical energy method, stress wave method, finite element method, boundary element method, rail-wheel noise model;
  5. Human response to vibration: vibration regulations, human response to vibration, comfort index for rail vehicle;
  6. Modal testing;
  7. Source identification;
  8. Room and architectural acoustics.

With these labs and faculties that are specialized in the theories of vibration and acoustics, CSVR has become one of the best institutes in Taiwan for undertaking researches in acoustics and vibration.

Underwater acoustic and hydrodynamic research center

This center was established in 1999 to manage the operation of our medium cavitation tunnel and large low background noise cavitation tunnel.

We have two areas of study: (1) the flow field and associated hydrodynamic phenomena of high-speed submerged bodies with complicated geometry; (2) the control of cavitation inception and characteristics of the acoustic field induced by cavitating and non-cavitating propellers.

The medium cavitation tunnel tests the performance (shaft thrust, torque, vertical and horizontal force) and cavitation behavior of propellers for high-speed crafts at inclined shaft conditions. There are two dynamometers and a pressure fluctuation measuring system available in this tunnel, allowing us to test contra-rotating propellers and measure pressure fluctuation induced by cavitating propellers.

The large cavitation tunnel is completed in December, 2001. Low background noise is our most important design goal. The test section is 10m in length, 2.6m in width, and 1.5m in height. Test speeds can reach as high as 12m/sec. An anechoic acoustic chamber is located beneath the test section. In this chamber, a matrix hydrophone arrary with 60 hydrophones is installed to take accurate measurement of all kinds of noise generated by the testing body in the test section. This tunnel is equipped with a very powerful contra-rotating dynamometer, a six-component balancer and other sophisticated measuring systems.

Small business computer center

The Small Business Computer Center has been established to research and develop applications on computer technology and consultation especially for small business. The five main services are:

  1. Research and development of computer technology
  2. Initiation of projects supported by the government or civil organizations
  3. Trainings for the government or civil organizations
  4. Consultation for the government or civil organizations
  5. Extension education on computer technology
