In his 2008 essay "Zur frühen Geschichte und Typologie der Klanginstallation" (On the Early History and Typology of Sound Installation), Volker Straebel identifies Max Neuhaus as the central figure who established the "sound installation" as an autonomous artistic category.
The "Invention" of the TermStraebel emphasizes that Neuhaus was the first to explicitly use the term "sound installation" in 1967 to describe his work Drive-in Music..
Straebel defines the sound installation as a site- and situation-specific work where sound is the primary characterizing element, distinct from traditional music or radio art because it cannot be subsumed by established forms.
Straebel notes a mid-1960s shift where "sound installation"—previously a technical term for setting up theater speakers—became a label for an artistic object created through sound emission.
