Soundscape Ecology Research Projects
Our most recent research thrust in the HEMA lab has been the exploration of sound dynamics in landscapes. We refer to this area of discovery as “soundscape ecology”. We are interested in characterizing the patterns of sounds that occur across different spatial extents and time periods. The connection to land use is obvious, we are interested in the types of sounds that occur in various major land use types and how planning and management might impact the quality and quantity of natural sounds in these environments.
Key Papers, Databases, and Tools
BioScience paper - This section contains the sound files of the Pijanowski et al. (2011) BioScience article titled "Soundscape Ecology: The Science of Sound in the Landscape."

Soundscape Data Sites
Tippecanoe Soundscape - This site contains an interface to over 32,000 15-min recordings made in 2008 at 7 sites in Tippecanoe County, Indiana. Each 15-min recording was analyzed for the amount of acoustic diversity and as well as the composition of acoustic frequencies. Recordings started at the top of every hour. The recordings were stored originally as wav files in 44.1 kHz, 16 bit format. Files were compressed to FLAC for long term storage and to MP3 for listening over the web.
La Selva Soundscape - This site contains over 9,000 recordings made in 2008 at 24 sites in the La Selva Field Station and the Braulio Carrillo National Park, Costa Rica. The sites covered a range of elevations, from 100 meters to about 600 meters above sea level.
Wild Sanctuary - Home to the largest private archive of natural sound. A worldwide collection of over 3,500 hours of wild soundscapes and nearly 15,000 species. Their mission is to help connect people to the wild by preserving, presenting, and protecting the voice of the natural world.
