singing sand
Humming desert grains
Singing sand refers to sand that produces audible sounds when disturbed by wind or movement.
The phenomenon occurs on certain beaches and desert dunes where dry, rounded grains of uniform size create squeaking, humming, or booming sounds when walked on or blown across.
We heard the dunes singing as the wind picked up.
The effect depends on specific conditions of grain size, moisture, and silica content.
