Miles away from the nearest road in Colorado’s Wheeler Geologic Area, the problem of noise pollution hit home for conservation biologist Rachel Buxton.
‘It was a gorgeous, remote valley, and then a plane flew over and you could hear the noise for ages as it reverberated in the valley,” she says. “I remember thinking, ‘wow, this is a really pervasive issue.’”
Buxton teamed up with researchers from the National Park Service and Colorado State University to author a 2019 study documenting manmade noise in U.S. national parks.
The study was part of a growing pile of research exploring noise’s negative impacts on animals and humans alike. Noise makes it hard for animals to find food and mates and can lead humans to suffer stress, high blood pressure and other ailments.
