Singing dunes are natural phenomena found in various desert regions around the world, where sand dunes produce a sound resembling music or singing when the sand grains move. This occurs when the sand is dry and the conditions are just right, allowing the grains to slide over one another, creating vibrations that generate sound waves. The sounds can vary in pitch and volume, often described as a low hum or a deep roar. Notable locations for singing dunes include the Great Sand Dunes National Park in the United States and the Liwa Desert in UAE. These unique features attract visitors and researchers interested in their acoustic properties.
