Sound recording of a silver-haired bat at BioBlitz 2016 in Washington, D.C.
Why parks record sound
The NPS Natural Sounds and Night Skies Division monitors soundscapes in parks across the United States. Natural quiet is treated as a resource to protect, like clean air or dark skies: noise from aircraft, vehicles and machinery can mask animal communication and change the experience of a place.
