The purpose of the International Institute of Acoustics and Vibration (IIAV) is to advance the science of acoustics and vibration by creating an international scientific society that is responsive to the needs of scientists and engineers in all countries whose primary interests are in the fields of acoustics and vibration. The Institute cooperates with scientific societies in all countries and with other international organizations with the aim of increasing information exchange by sponsoring, cosponsoring or supporting seminars, workshops, congresses and publishing journals, newsletters and other publications. The IIAV provides a refereed journal on paper, the International Journal of Acoustics and Vibration (IJAV), electronic newsletter and the International Sound and Vibration Digest (ISVD) for all members as part of their dues.
