Jet Aeroacoustics
- Military Fighter Aircraft
- Rockets
- Explosive Volcanoes
Source Characterization Methods
- Near-field Acoustical Holography
- Vector Acoustic Intensity
- Phased-Array Analysis
- Equivalent Source Modeling
Nonlinear Acoustics

- Blast Noise Propagation
- Perception of Nonlinearly Propagated Noise
Noise
- Acoustical Design of an Aircraft Gatling Gun Range
- Active Noise Control of Cooling Fans
We have studied the noise source generation mechanisms in order to optimize the active control process and achieve global reductions in desktops, server trays, and laptops.
Musical Acoustics

- Acoustics of the Balinese Gamelan
Physics and Chemistry Demonstrations
- The Rubens Tube
- Acoustics of the Balloon Lens
- Acoustically-driven Vortex Cannon
- Audio-frequency Line Array
- Weak-shock Propagation Demonstration
- Auditory Risk of Chemistry Demonstrations
