The Listenn Project is grounded in the field of Acoustic Ecology which studies and documents the sounds of the environment. The Listenn team pursues questions about the role and function of sound and the perception of sound for a deeper understanding of place, presence, belonging and sustainability issues. The team has already established one of the largest online databases of surround sound field recordings in the American Southwest and is expanding with partners in Germany, Mexico and Chile. Further growth is expected over the next decades through including field recordings made by park communities and visitors across the globe. Over time the sound recordings will critically indicate changes in land use and species adaptation and point to the importance of the sonic environment for wildlife and our communal, social and global health.
