Listening Beyond the Human: The Autonomous Recording Unit and the Ethics of Sound in Biodiversity Conservation

Sound technologies and sound sensor networks play a crucial role in our understanding of biodiversity loss in conservation biology and the environmental sciences. Among these technologies, the autonomous recording unit (ARU) has been widely used for studying longitudinal biodiversity loss. This article draws on fieldwork conducted in 2016 and 2017 at a bioacoustics research laboratory to explore the significance of the ARU, developed by Wildlife Acoustics, as the central component of the research network for biodiversity conservation. While it is commonly acknowledged in Science and Technology Studies (STS) that research instruments are not neutral data collectors, this article examines how the ARU is deployed and programmed, and how it transcends the limitations of human-centered listening by (a) shifting the focus away from the perceiving human subject and (b) promoting a global ethic of response and responsibility as sound becomes more democratized in scientific practices.
