The adapted version of radio.earth.Weimar for The Pond project features two live broadcasts transmitting the acoustic atmospheres of underwater environments from two ponds in Weimar: one in Ilm Park and the other in the rainwater garden pond on the Bauhaus University Weimar campus. Using mobile microphone units with hydrophones, these broadcasts allow listeners to immerse themselves in distinct yet interconnected underwater soundscapes over extended periods. The project integrates the perception of natural and environmental sounds into The Pond’s research and learning processes, inviting an ongoing engagement with seasonal changes and fostering an intensified sensory connection across spatial distances.
Initiated in the summer semester of 2024, radio.earth.Weimar is a long-term collaboration between Acoustic Ecologies and Sound Studies at Bauhaus University Weimar and the international project radio.earth by Udo Noll. Together with students, Udo Noll and Kerstin Ergenzinger developed one mobile microphone unit powered by a power bank and two semi-stationary, solar-powered units. The mobile system supports regular live-listening practices, enabling participants to attune to the dynamics of ecosystems and their transformations over time. At the same time, the project contributes to the wider radio.earth community, an established participatory art and radio initiative dedicated to the perception of ecological crises through sound.
