Similar to its visual counterpart, a sonic landscape exists as an accumulation of presences and absences. A topophone (from τόπος – place or location + phōnē – voice) is a solar-powered sound device based only on analog electronic components that intervenes in an existing landscape. Powered only by solar energy and creating insect-like vocalizations of different rhythms and timbres under changing light conditions, the topophones create connections between a place, speech, and hybrid nature/technology sounds. The sounds emitted are simultaneously disruptive and strangely familiar – technological echoes of insect and bird voices. Each topophone is equipped with a custom-shaped lime-green mouthpiece around its piezo speaker. This mouthpiece visualizes the waveforms of spoken words. The visualized vocabulary recalls negotiations or confrontations between technology, ecology, and profit. In this edition of the project, we have shaped the topophones’ mouthpieces based on the audio-waveform of names of highly toxic pesticides that poison and kill pollinators. These names, which include Silencer, Swagger, Warhawk, Venom and Hero speak a history of aggressive battle and annihilation that is part of industrial agriculture’s perception of nature that can be easily categorized as good and bad in the pursuit of ever increasing yields and profits.
