Acousmatic sound

The word acousmatic, from the French acousmatique, is derived from the Greek word akousmatikoi (ἀκουσματικοί), which referred to probationary pupils of the philosopher Pythagoras who were required to sit in absolute silence while they listened to him deliver his lecture from behind a veil or screen to make them better concentrate on his teachings.

In 1955, Jérôme Peignot and Pierre Schaeffer were the first to use the term acousmatic to define the listening experience of musique concrète.

The concept of reduction (epoché), as used in the Husserlian phenomenological tradition, underpinned Schaeffer's conceptualization of the acousmatic experience.

Schaeffer derived the word acousmatique from akousmatikoi (hearers), a term used in the time of Pythagoras to refer to his uninitiated students.

The use of silence related to the protocols of rituals connected with the mystery-like instruction and religious ceremonies of the Pythagorean order.
