Singing Sand Dunes
From Biocrawler, the free encyclopedia.
The Singing Sand Dunes, also described as roaring, booming, squeaking, or musical, is the name given to a natural sound phenomenon that occurs in about 35 deserts around the world. The sound is similar to a loud, low-pitch, rumble, and it emanates from the crescent-shaped dunes, or barchans, without any direct wind involvement. Although the phenomenon has not been fully understood, scientists believe that it is a resonance from the sliding of similarly-sized grains of sand during avalanches, reverberating over a more solid batch of sand.
