In acoustics, the group is led by Dr. Bliss whoose primary effort is in the application of ANM to structural acoustics, particularly to acoustic scattering from submerged elastic bodies with structural discontinuities. He has also developed a method called Alternate Resonance Tuning (ART) to prevent low frequency sound transmission into flexible wall enclosures, with applications to aircraft interior noise. He also conducts research on mathematical homogenization applied to structural acoustic systems, and on general boundary conditions for bulk-reacting sound absorbing surfaces.
