About this sound
Recorded from the sidewalk under the historic Francis Scott Key Bridge located in Washington, DC. This audio clip features city sounds and sounds of cars whooshing by under the bridge.
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.
