Natural sounds are an important part of the experience of being in wild places. Some sounds are gentle and we may not even notice them much in the background; think of the sounds of flowing water, bird songs, frogs, insects, the wind. Other sounds are dramatic, awe-inspiring; think of wolf howls or a glacier calving.

Natural sounds can be masked by human sounds such as engine noise (from cars, all-terrain vehicles, snowmachines, boats, and planes) and not only disturb our enjoyment of the natural world, but also disrupt natural ecosystems. Wildlife use sounds to communicate. Young vocalize to communicate with their mothers; calls are used to find mates; warning sounds are made to raise the alarm about predators. These sounds are important in both terrestrial systems as well as marine ecosystems (including underwater communication among whales, for example). The National Park Service documents and monitors soundscapes to ensure natural sounds are protected.

    In 2008, 12 visually impaired students along with sighted teenagers and guides embarked on a Colorado River trip through Grand Canyon National Park. It was the first of its kind. The data they collected helped the park do further soundscape monitoring.

    Map shows Glen Canyon National Recreation Area, Lake Powell, and surrounding Navajo Indian lands.

    Noise models are effective tools for showing how noise distributes across park landscapes. Scientists in the Natural Sounds and Night Skies Division created a noise map of Lake Powell at Glen Canyon National Recreation Area, Utah that shows the distribution and duration of aircraft noise above Lake Powell.

    Soundscapes, the combined sounds from natural and non-natural sources, are recognized as an important resource in national parks. In the year 2000, park managers recognized that the natural soundscape of Denali was increasingly affected by non-natural sounds. Because preserving the natural soundscape also helps preserve the associated wilderness values and visitor experiences, a soundscape program was initiated.

    When the weather warms, national parks across the country rouse from winter’s sleep. The sounds you hear in parks reflect this seasonal change. They contribute to the unique soundscape of these special places, and are among the resources that the National Park Service protects.

    In an NPS partnership with the Colorado State University Sound and Light Ecology team, undergraduate students working in the Listening Lab discover and assess a spectrum of acoustical data collected in national parks around the country. The primary goal of the lab is to aid in the understanding of natural soundscapes by providing a resource to efficiently analyze the thousands of hours of natural and anthropogenic, or human-caused, sounds recorded each year.
