Desert dunes that sing!

Badain Jaran Dunes

The tallest stationary dunes on Earth can also sing! Over 1,600 feet tall, the Badain Jaran Desert Dunes in China are roughly the same height as the world’s tallest buildings and hold a mysterious property known as singing sands, whistling sands, or booming dunes.

This rare occasion emits a sharp, loud noise that can be maintained for more than a minute. It is believed that it is caused by an electrostatic charge that is generated as wind pulls the top layers of sand down a dune slope, producing a low pitched rumble that can reach over 105 decibels.
