The singing sand dunes in Kazakhstan’s Altyn-Emel National Park make a strange, melodious sound. Anyone who visits them is amazed by the sound, like a cello or bassoon, coming from the dunes themselves. The sound is even louder and clearer if you slide down from the top of the hill.
Altyn-Emel National Park is Kazakhstan's largest reserve, located near the Chinese border. It is becoming increasingly famous for its melodious sand sounds.
This sand dune is 150m high and about 3km long. Any visitor coming here is extremely surprised by the sound coming from the sand dune itself. The sound will be even louder and clearer if you slide down from the top of the hill.
The sound is intermittent, lasting only a few minutes at a time, and can only be heard in dry weather. Many visitors also say that the sound from the sand dunes is quite similar to the sound of a cello or bassoon.
Although there is no consensus on the explanation of this phenomenon, most scientists believe that the friction between sand grains along with the impact of wind creates this sound. When sliding from the top down, the sand moves and rubs against each other more, so the sound will be heard more clearly.
Scientists have also discovered that this type of sound is usually only emitted in light windy and sunny weather conditions. In addition, the drier the sand grain, the louder the sound. On wet days or in winter, the sand grains are often "silent".
In this park, archaeologists have also discovered many animal fossils, from rhinos to ancient turtles, some of which are millions of years old. However, the most mysterious thing in Altyn-Emel is the singing sand dunes.
Currently, this reserve is also home to more than 260 animal species, very rich in breeds and species.
