“The discovery of this miraculous natural phenomenon will provide technical support for the development and protection of tourism resources in Hainan,” said the Northwest Institute of Environmental Resources and Resources (NIEER) of the Chinese Academy of Sciences. , said.

“Singing” sand – also known as “shaking”, “whistling” sand or “music” sand – usually occurs in sandy areas of deserts or coastlines. Due to a combination of physical characteristics, including grain size and composition, sand has naturally generated sound in the wind.

China has recorded sand “singing” in Many areas, including the famous Sand Sing Mountain, are located near the Mogao Thousand Buddhas Cave in Dunhuang City, northwest Gansu Province. Such sights are very attractive to tourists who want to experience the strange phenomenon.

But here is the first time “singing” sand has been recorded on the coast of China, tXinhua pig.

“The distribution of coastal sandbars is considered to be a reflection of the quality of the beaches. It has long been assumed that coastal China does not have quality sandbanks, and our latest study has offers a new answer,” said Qu Jianjun, a NIEER researcher and study leader.

The NIEER team also discovered many singing sands along the coasts of Clearwater Bay, Shenzhou Peninsula and other areas in Hainan.

The study shows that the unique geomorphology and breaking dynamics of these bays form fine-sized coastal sand grains.

The scientists studied the characteristics of coastal singing sands, such as mineral composition, grain size, surface structure and acoustic characteristics, and compared them with regional singing sands. desert.

The surface of coastal sands is often sunken in a typical V-shape, formed by underwater mechanical corrosion.” The surface porous physical structure is an important factor in controlling the acoustic mechanism. the sound of singing sand,” said Mr. Qu.

However, the frequency spectrum of coastal singing sands is narrower than that of desert singing sands, with a high proportion of sand components and relatively sharp sound, according to the study.

In the world, there are famous singing sand dunes in California, Northern Michigan, Nevada (USA), as well as the Namib desert in Africa and the area near the city of Mesaieed in Qatar. Music created by sand can also be heard in South Sinai, Egypt, and Odashi, Japan.
