Theoretical and Applied Acoustics

The Walker Department of Mechanical Engineering has supported a strong concentration in the research area of Theoretical and Applied Acoustics for more than five decades. The foundation of this program of work is a sequence of eight core graduate courses, four of which cover the foundations of theoretical acoustics: two courses on physical acoustics, one on nonlinear acoustics, and one on advanced topics in acoustical wave phenomena, and four of which cover traditional areas of applied acoustics: acoustical transducers, underwater acoustics, architectural acoustics, and ultrasonics.

These core courses are supplemented by a broad diversity of acoustics-related courses throughout not just the Cockrell School of Engineering but also the Jackson School of Geosciences, the College of Communication, and the College of Fine Arts.

The faculty in Theoretical and Applied Acoustics perform research on problems of both a basic and applied nature in physical acoustics, engineering acoustics, and ocean acoustics. Basic research is conducted on modeling acoustic and elastic wave propagation in complex media that include metamaterials, composites, multiphase media such as marine sediments, and nonlinear tissue-like media, and on modeling bubble dynamics in the context of diagnostic and therapeutic ultrasound as well as underwater applications. Applied research is conducted on topics such as new acoustical transduction materials, ultrasonic nondestructive testing, energy absorption and vibration isolation using negative-stiffness-bearing structures, acoustic cloaking, nonreciprocal acoustic and elastic wave devices, underwater anthropogenic noise abatement, animal bioacoustics, and scattering, reflection and transmission at the ocean bottom.
