HOW DO WE LISTEN TO THE EARTH? THAT IS THE CENTRAL QUESTION POSED IN _GEOSONICS: LISTENING THROUGH EARTH'S SOUNDSCAPES_. Working across sound studies, media theory, and environmental media studies, Joshua Dittrich explores the material and metaphorical geology of the sonic environment. In an epoch of climate crisis, environment is no longer a neutral background, site, or simple “surrounding”: environment is immanently implicated in the chains of mediation that make up the material and imaginative infrastructure of our lives. The analytical task of_ Geosonics _is to tune into that infrastructure through sound. Drawing on influential work in sound studies around the concept of transduction, this book explores how listening does not take place in a pre-existing soundscape, but rather makes place by etching out a mediated, mutually constitutive set of relations between listeners, media, and environments.
