Acoustics

Acoustics is one of the oldest branches of science and has a broad scope of applications, from the detection of microscopic cracks to the measurements of the global ocean temperature. Acoustics has become an indispensable tool for medical diagnostics, underwater and geophysical exploration, engineering, art and life sciences.

Acoustic research in the Davidson Laboratory is involved in various innovative research initiatives motivated by advanced scientific and technological needs. One of the strengths of our program is the study and application of the nonlinear interaction of acoustic and vibration energy in various media and materials. The lab uses state-of-the art equipment such as multi-channel signal analyzers, data acquisition and processing systems, wide range of sound and vibration measuring and generating instrumentation, including unique non-contact ultrasonic, microwave and laser-doppler vibrometers.

Our acoustic research faculty maintains strong relationships and has access to facilities of the Department of Civil, Environmental and Ocean Engineering; and the Mechanical Engineering and Materials Science Departments including their anechoic chamber, electron microscopes, compression/tension universal testers, etc.

Current research thrusts include:

  • Nonlinear vibro-acoustic nondestructive testing.
  • Acoustic and vibration characterization of porous materials
  • Detection and characterization of submerged/buried objects such as land mines, pipes, etc.
  • The use of powerful sound and vibration for biofouling control.
  • Development of low frequency underwater sound sources.
  • Noise and vibration control
