In our image-saturated contemporary society, sight often eclipses other senses that are vital to understanding the unseen dynamics of our sensory relationship with environments. As a counter- project to the hegemony of images, the act of listening opens up new possibilities for exploring both built and natural environments and moving our attention to granting a voice to more-than- human agencies. Ecotones showcases investigations on the relevance of sound in territorial studies. It is developed as a curated collection of texts from various disciplines and practitioners exploring spaces, territories, and ecologies through sonic endeavors. With a variety of formats, from essays and fiction pieces to situated case studies, Ecotones narrates sound as a medium, the act of listening as a political tool, and sonic experiments.
