The research group in Acoustics and Dynamics is devoted to an exploration of vibratory phenomena that are encountered in structural systems, in the air, and in the water. In fluid media, these vibrations are called sound, so the area is referred to as acoustics, but many of the questions and research tools are common to all areas. The basic objective shared by the projects is to understand the mechanisms by which the vibration or sound is initially generated, or modified as it propagates, or detected by the receiving transducer. In many cases, this information can be used to characterize the propagation medium. In some cases, this will lead to concepts for reducing the signal, but there are many situations where it is desirable to enhance it.
