The sound of sand dunes does not emit intermittently, each lasting only a few minutes.

This sand dune is 150m high and about 3km long. Any visitor who comes here is amazed at the organ-like sound coming from the sand dune itself. Even the sound will be louder and clearer if you slide down from the top of the hill

This sound is not continuous, each lasting only a few minutes and can only be heard when the weather is dry. Many tourists also think that the sound from the sand dunes is quite similar to the cello or bassoon.

According to the Mother Nature Network, many dunes in the deserts of Africa, China, Qatar and California, USA, emit intense sounds, like the hum of bees or the Gregorian hymn.

Sliding down from the top causes sand to move and rub more together, so a clearer sound will be heard. The scientists also found that the sound emitted by the sand dunes depends on the size and speed of the sand movement. But the fact they can not explain the cause of the phenomenon.
