BOB HIRSHON (host):

Our noisy wilderness. I’m Bob Hirshon and this is Science Update.

[nature sounds] Visitors come to national parks and other protected areas not only for their magnificent scenery, but also for their natural soundscapes: singing birds, water rushing over rocks, and wind in the trees. But those sounds now have competition from human-produced noise. In the journal Science, Colorado State University conservation biologist Rachel Buxton and her colleagues report analyzing a million hours of acoustic measurements taken from 492 sites. They found that in over 60% of the sites, background sound was at least double what it would be without human input.

RACHEL BUXTON (Colorado State University):

And sound at these levels impacts both the human experience in national parks and have a range of repercussions for wildlife.

The work could help pinpoint areas where noise reduction could have the biggest benefits. I’m Bob Hirshon, for AAAS, the science society.
