Acousmatic sound is sound one hears without seeing an originating cause. The word acousmatic, from the French acousmatique, is derived from akousmatikoi, a term used to refer to probationary pupils of the philosopher Pythagoras who, so that they might better concentrate on his teachings, were required to sit in absolute silence while listening to their teacher deliver his lecture from behind a veil or screen. The term acousmatique was first used by the French composer, and pioneer of musique concrète, Pierre Schaeffer. In acousmatic art one hears sound from behind a 'veil' of loudspeakers, the source cause remaining unseen. The term has also been used by the French writer and composer Michel Chion in reference to the use of off screen sound in film. More recently, in the article Space-form and the acousmatic image (2007), composer and academic Prof. Denis Smalley has expanded on some of Schaefers' acousmatic concepts. .
