The NPS is revising its operational policies and procedures to facilitate, to the fullest extent practicable, the protection, maintenance, or restoration of the natural soundscapes associated with units of the national park system. Natural sounds are vital to the natural function of many parks, and may provide valuable indicators of the health of various ecosystems. The natural sound environment is recognized as one of the resources found in parks, and is highly valued by most park visitors. Increasingly, even those parks that appear as they did in historical context no longer sound the way they once did. Natural sounds are slowly and inexorably being masked or obscured by a wide variety of human activities. Soundscape preservation and noise management is one dimension of the complex problem the NPS faces in preserving park resources unimpaired while providing appropriate enjoyment for current and future generations.
