COMSOL Conference 2013

Acoustics and Vibrations

Acoustic pressure wave propagation in fluids can result in vibrations in the surrounding structure. View the papers, presentations, and posters on this page to learn how multiphysics simulation was used to model physical phenomena such as acoustic scattering, transmission, and radiation for the design of devices such as mufflers, transducers, loudspeakers, and sound insulation materials.
