Booming Dunes of Badain Jaran Desert
The tallest stationary dunes on Earth also happen to sing
Category Natural Wonders, Geological Oddities
Badain Jaran Desert is home to the tallest stationary dunes on Earth. Reaching over 1,600 feet tall, they are roughly the same size as the world's tallest buildings. This area also shares a mysterious property with some three dozen other deserts around the world. Known as singing sands, whistling sands, or booming dunes, the dunes of the Badain Jaran Desert make a surprising amount of noise.
Singing sands are generated when the desert wind pulls the top layer of sand off layer below. It is believed that the noise is generated by electrostatic charge this action creates. On a small scale, such as a beach, this phenomenon creates a high-pitched sound, but on a much larger scale, it can emit a low-pitched rumble or booming sound, and at up to 105 decibels, it can be quite loud.
Despite singing sands and booming dunes being a feature shared by some 35 deserts and beaches around the world, the mechanism that makes the sound is still not fully understood.
