The Natural Sounds and Night Skies Division of the U.S. National Park Service has collected month-long acoustic recordings at more than 300 sites in 73 park units located throughout the United States, dating back to 2000. Each monitoring session lasted 25 days or more; some sites were monitored more than once. At all sites a calibrated Sound Level Meter recorded acoustic data in one-second, one-third octave band resolution; at many sites, simultaneous continuous acoustic recordings were collected using a digital audio recorder. These data were analyzed to identify broad patterns in bioacoustic activity within one-third octave bands. These bioacoustical patterns were analyzed in relation to site characteristics, seasons, and anthropogenic noise levels to identify significant associations. The resultant model could be used to produce a map predicting bioacoustical activity throughout the coterminous United States.
