Sound art is an artistic discipline in which sound is utilised as a medium. Like many genres of contemporary art, sound art is interdisciplinary in nature, or takes on hybrid forms. Sound art can engage with a range of subjects such as acoustics, psychoacoustics, electronics, noise music, audio media, found or environmental sound, explorations of the human body, sculpture, film or video and an ever-expanding set of subjects that are part of the current discourse of contemporary art.
