Description: If a tree falls in the woods, and no one is around to hear it... it may have been recorded!
Efforts to protect the acoustical environment in our national parks are driven by NPS management policies. But before any action can be taken, park planners and managers need reliable data about a park's existing acoustical environment. What natural and cultural sounds can be heard at the park? What types of human-caused noises can be heard? Where, when, and how often are they heard, and how loud are they?
Through sound monitoring efforts, parks can learn about the acoustical environment as a whole and identify desirable and appropriate sound sources, as well as those that are undesirable in the park setting. Information gathered can then be used to identify the potential impacts of non-natural sounds and proposed developments or actions that may affect the acoustical environment.
Elk bugling in the cool autumn air of Rocky Mountain National Park, waterfalls thundering in Yosemite Valley, cannons firing at Fort McHenry National Monument, the quiet hush among giant redwoods--these are the sounds that make visiting our national parks a unique experience.
Natural and cultural sounds awaken the sense of awe that connects us to the splendor of national parks and have a powerful effect on our emotions, attitudes, and memories. Who can forget the flash of adrenaline from the sound of looming whitewater or the lightning bolt that cracked just a little too close? The National Park Service regards these sounds as part of a web of natural and cultural resources that must be protected.
Like thunder rumbling in the distance, threats to natural and cultural soundscapes are increasingly difficult to ignore. From growing demands for park overflights and expanding energy development to greater numbers of park visitors, potential noise sources are proliferating. So too, however, are efforts to understand their effects and avert negative impacts.
