This thesis argues that the Australian Broadcasting Corporation’s sound art program The Listening Room has been , both through broadcasting and related activities, a major factor in the life and growth of sound art in Australia. The thesis also argues that, internationally, The Listening Room is accepted as a leading member of the world sound art community by its contribution to the artistic development and wider recognition of the genre. In order to examine the influence of The Listening Room, interviews and case studies with Australian composers and overseas producers and observers are recounted and analysed. Finally, pertinent data from historical summaries, interviews and case studies are conflated to demonstrate the depth and significance of The Listening Room. / Doctor of Philosophy (PhD)
