A sound installation is a type of artwork that primarily uses sound as its medium. It can take many different forms, including site-specific installations in which the sounds are designed to interact with and enhance the physical environment they're installed in, or more traditional gallery installations where visitors listen through headphones or speakers. Sound installations often incorporate a variety of audio elements such as spoken word, music, environmental recordings, or other sonic effects to create an immersive experience for the viewer/listener. The goal is usually to evoke emotions, provoke thought, or simply provide an engaging and memorable auditory experience.
