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.
