Hidden in the vast landscapes of Altyn-Emel National Park, Kazakhstan’s famous Singing Dune (also known as the Singing Barchan or Aigaikum) is a natural wonder that produces eerie, resonant sounds when the wind blows or sand slides down its slopes. Often called a “singing mountain,” this massive sand formation hums like a deep organ or distant aircraft engine, captivating visitors and scientists alike.
What Makes the Dune “Sing”?
The humming sound occurs when dry sand grains rub against each other as they avalanche down the steep slopes, especially in windy, dry conditions. Friction creates vibrations, amplified by the dune’s size and shape.
- Sound description: A low-frequency rumble, often compared to organ music, a roaring plane, or thunder.
- Best time to hear it: Strong winds or sliding down the dune yourself larger sand movements produce louder “songs.”
- Scientific explanation: Caused by synchronized grain movement and possible static electricity in the quartz-rich sand.
