A Symphony of Trees, Grasses, Birds and Streams

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. The National Park Service regards these sounds as part of a web of natural and cultural resources that must be protected. From growing demands for park overflights to expanding energy development, noise sources are proliferating. But so are efforts to understand their effects and avert negative impacts.
