Acoustics is the science of mechanical waves in gases, liquids, and solids. It deals with the interaction between sounds, objects, humans and animals, including sound perception and production.

The Acoustics Research Institute (ARI) is committed to application-oriented fundamental research in the field of acoustics. ARI consists of four groups working in close collaboration to address these research demands. Each of the groups is active in both fundamental and applied research, aiming for scientific excellency, particularly in interdisciplinary projects.
