Abstract

The spaces between the modernist categories of human and nonhuman, or nature and culture, are collapsing in the Anthropocene. As human technological influence continues become evidenced as a global geologic force, ‘liminal spaces’ expand. Liminal spaces are spaces at the intersections and aggregations of human- and nonhuman-animal umwelten mediated by technology. Soundscapes, the collection of human and nonhuman created sounds of a particular place and time, give us unique access to the semiotic exchanges that constitute those spaces. Soundscape ecology, the study of ecosystemic relations through sound, is a method by which to engage and understand those liminal spaces. Understanding liminal spaces in this context of soundscape ecology offers insights into new ways in which organisms relate to and within their environments through sign exchange; or, new ways animals engage complex worlds of experience. In this paper I articulate this argument and define ‘sonic liminality’ as a biosemiotic process of the creation and engagement in hybrid natures. I examine umwelt engagement through a specific case study: analysis of soundscapes at a local zoological park in the southeastern United States. I argue that the digital technology-driven empirical work of soundscape ecology gives semioticians access to informational ecosystems, and therefore to the ways in which information transforms the boundaries between individual organisms and their built and natural environments.
