Auditory Biomechanics - I

Developed an optical coherence tomography system to measure the tissue

vibrations inside the inner ear in live rodents. Used it to investigate soundprocessing in the inner ear.

Current/Future Research

Acoustics

Improve the transmission loss performance of vibro-acousticsilencers

Acoustic characterization of porous materials including periodic

foams

Noise control for electronic cooling applications

Auditory Biomechanics

Design novel microscale sensors to measure both pressure and

vibration in the inner ear

Wave propagation mechanisms involved in otoacoustic

emissions (which are sounds emitted  by the ear)

Processing of sound by the inner ear
