音乐沙在夏威夷群群岛的哈那伊沙滩上,有一片绵延800多米,高达18米的沙丘,它由珊瑚、贝类及砂粒堆积而成。每当人们迈步在沙丘上时,就会听到脚下发出动听的音乐。如果用两手抓起一把沙子用力磨擦,手中的沙子也会发出奇妙的声音来。据科学家分析,这是由于这里的沙子被海水和雨水打湿以后,随着水分的不断蒸发,产生振动,而在沙子表面的空气薄层就在振动的情况下产生音响,于是就发出了节奏不同、音色各异的音乐。
Musical Sand On the sandy shores of Hanayi in the Hawaiian Islands, there is a sand dune stretching over 800 meters and up to 18 meters in height. It is made up of coral, shellfish and sand. Whenever people move in the sand dunes, they will hear the sound of music at the foot. If you use both hands to grab a sand friction, the hands of the sand will make a fantastic sound. According to the analysis of scientists, this is because after the sand is wetted by seawater and rain water, vibrations are generated as the water evaporates. A thin layer of air on the surface of the sand generates sound when it vibrates. As a result, a rhythm Different, different tonal music.
