Acousm
Acousm, derived from the Greek word "akousma" meaning "hearing," refers to a particular type of sound that is heard without being directly visible or identifiable. It is commonly associated with the experience of sound in a purely auditory manner, dissociated from its visual or physical source. Acousm can include various types of sounds, such as voices, music, or environmental noises, and it often involves an element of ambiguity or mystery, as the origin or cause of the sound remains hidden or unknown.
In the context of philosophy and sound studies, acousm is often used to describe the phenomenon of sound being experienced independently of its visible manifestation. This concept highlights the significance of sound perception and the role it plays in our understanding of the world. Acousm allows us to focus solely on the auditory aspects of sound, providing a unique sensual experience and opening up possibilities for interpretation and imagination.
In contemporary music and audiovisual arts, acousm is often utilized to create immersive and abstract sonic environments, challenging traditional notions of sound and its relationship with the visual. It enables artists to explore the boundaries between different forms of sensory perception and encourages listeners to engage with sound on a deeper, more introspective level.
Overall, acousm is a term that encompasses the intriguing and multifaceted nature of sound itself, emphasizing its independent existence and its capacity to evoke emotions, thoughts, and associations without the need for direct visual or physical presence.

The word "acousm" has its etymology in the Greek language.
The term "acousm" comes from the Greek word "akousma" (ἀκοῦσμα), which means "something heard" or "a hearing". "Akousma" is derived from the Greek verb "akouein" (ἀκούειν), which translates to "to hear" or "to listen".
In ancient Greece, the word "akousma" was primarily used to refer to the teachings of Pythagoras, the ancient Greek philosopher and mathematician. Pythagoras had an inner circle of students known as the "Akousmatikoi", who were disciples dedicated to learning his philosophical and mathematical concepts through oral transmission and secret teachings.
