Some Sand Dunes Sing And Have Musical Booms
- 9 years ago
A recently published study describes the reason why sand dunes are often described as musical.
Some sand dunes are known to make noises that resemble musical tones.
Now, a recently published study describes why and how these noises are made.
Using instruments called geophones which pick up on subterranean vibrations, researchers have found that “waves travelling through the dune move individual grains of sand.”
One sound which they call “burping” is caused by non-linear waves near the surface, and the other sound labeled “booming” is the result of linear waves in the dune’s interior.
The phenomenon is made possible due to
