Have you ever heard that the sand of Mingsha Mountain can sing?It is an amazing natural phenomenon as well as a mysterious geological wonder. Today, I will introduce you to why the sand of Mingsha Mountain makes a sound, what are the characteristics of this sound, and how this sound has been studied and interpreted by scientists, so that you can have a comprehensive understanding of this wonderful sound.
Located about 6 kilometers southwest of Dunhuang City, Gansu Province, Mingsha Mountain is one of the four major Mingsha Mountains in China and the largest Mingsha Mountain in the world. The sand of Mingsha Mountain is a fine grain of sand composed of quartz, due to the action of the wind, when the sand slides on the dunes, it will make a sound similar to a musical instrument, some like a drum, some like a harp, some like a bell, and some like a flute, the sound is different, light or loud, giving people a wonderful auditory enjoyment. Why does the sand of Mingsha Mountain make a sound?This is a question that has puzzled people for thousands of years, and it is also an interesting scientific question. The ancients had various legends and speculations about the reason for the sound of the sand in Mingsha Mountain, some believed that there were gold and silver treasures buried under the sand mountain, some believed that there were gods living in the sand mountain, some believed that there were dragon kings in the sand mountain, and some thought that there were ghosts haunted by the sand mountain. These legends and speculations, while imaginative, do not conform to the principles of science.
With the development of science and technology, people have conducted in-depth research and exploration on the mechanism of sand sound in Mingsha Mountain, and discovered some meaningful laws and phenomena. Scientists have found that the sound of the sand in Mingsha Mountain needs to meet certain conditions, such as the shape, size, composition, water content of the sand particles, the slope of the dunes, the magnitude of the wind, and so on. If these conditions are not met, the sand will not make a sound, or the sound will be very weak. Scientists have also found that the sound of the sand in Mingsha Mountain has a certain frequency and tone, and the sound of Mingsha in different places is also different, some are low-pitched, some are high-pitched, some are single tones, and some are multiple tones. These sounds can be measured and analyzed with acoustic instruments, or they can be identified and appreciated with the human ear.
So, what is the principle of the sound of the sand in Mingsha Mountain?At present, scientists do not have a completely unified answer to this question, but there are some more reasonable hypotheses and explanations. The most influential of these are the "resonance hypothesis" and the "friction hypothesis". The "resonance hypothesis" holds that the sound of the sand in Mingsha Mountain is due to the formation of a resonance cavity by the porous structure on the surface of the sand particles, and the air between the sand particles vibrates and amplifies under the action of external forces, producing sound. The "friction hypothesis" holds that the sound of the sand in Mingsha Mountain is due to the friction and collision between the sand grains, which produces weak sound waves, which propagate and superimpose inside the sand dunes to form sounds. Both hypotheses have certain theoretical basis and experimental support, but there are also some shortcomings and doubts, which need further research and verification.
The sound of the sand in Mingsha Mountain is a magical natural phenomenon that not only shows the magic of nature, but also stimulates human curiosity and exploration. With the progress of science and the development of society, the research and utilization of the sand sound of Mingsha Mountain will be more extensive and in-depth, and contribute to the sustainable development of mankind.
