In this paper I will attempt to unite four areas of sound research:
1] Soundscape composition, in particular those compositions developed through the practice of soundwalking
2] Geosonification, the process of translating non-audible environmental data into sound
3] Sound activism, specifically when designed to raise awareness of the sound environment and change social and cultural practices
In bringing these distinct areas together, I will identify, compare and discuss each field, particularly with regard to subjectivity and listening attitudes between soundscapes and music, in an attempt to lay the groundwork for a theory of environmentally aware sonification practice defined as geosonification, specifically in response to climate change. I will argue that the act of listening through public soundwalks and other formal and informal exercises can build environmental and social awareness and promote changes in social and cultural practices.
