Singing Sand - in Dunes

In Dunes

Singing sand dunes, an example of the phenomenon of singing sand, produce a sound described as roaring, booming, squeaking, or the "Song of Dunes". This is a natural sound phenomenon of up to 105 decibels, lasting as long as several minutes, that occurs in about 35 desert locations around the world. The sound is similar to a loud, low-pitch, rumble, and it emanates from the crescent-shaped dunes, or barchans. The sound emission accompanies a slumping or avalanching movement of the sand, usually triggered by wind passing over the dune or by someone walking near the crest.

Examples of singing sand dunes include California's Kelso Dunes and Eureka Dunes; sugar sand beaches and Warren Dunes in southwestern Michigan; Sand Mountain in Nevada; the Booming Dunes in the Namib Desert, Africa; Porth Oer (also known as Whistling Sands) near Aberdaron in Wales; Indiana Dunes in Indiana; Barking Sands in Hawaiʻi; Mingsha Shan in Dunhuang, China; Singing Beach in Manchester-by-the-Sea, Massachusetts; near the Al Udeid Air Base west of Doha, in Qatar; and Gebel Naqous, near el-Tor, South Sinai, Egypt.
