Sometimes you just need a little peace and quiet.

Here's your guide to finding it.

The National Park Service has a whole team dedicated to measuring the din of daily life, analyzing millions of hours of sounds across the U.S. to determine where noise pollution is worst and where it's lightest.

In a map displayed this week at the annual meeting of the American Association for the Advancement of Science, the NPS' Natural Sounds and Night Skies Division laid out the state of sound from sea to shining sea and revealing that the Rocky Mountains are home to the quietest spots in the country.

On the other hand, manmade sounds blanket huge chunks of the Northeast, the Midwest, California, Texas and Florida.

In fact, loud is the norm east of the Mississippi River — check out the full map below for confirmation.
