Almost everyone loves to listen to music while driving down long stretches of roads. But what if the road itself provided the tunes? Thanks to the world’s musical roads, drivers can now enjoy music while taking road trips, even without the radio on.
How does a musical road actually work? It has to do with3 the vibrations created when a vehicle’s tires pass over grooves that are cut into the surface of the road. The closer together the grooves are, the higher the pitch. On the other hand, grooves that are farther apart will create lower notes. The first musical road was created in Gylling, Denmark, in 1995. The tune played was a simple group of notes in the key of F major.
To produce the desired effect, drivers must pass over the grooves at a certain speed. This is similar to the concept of vinyl records, which have to spin 45 or 33 times per minute. Signs often tell drivers the desired speed, and motorists must also make sure they hit the grooves head-on.

不需藍牙或立體音響就能聽到
幾乎每個人都愛在行駛漫長的道路時聽音樂。但如果道路本身就 能提供曲調呢?多虧了世界各地的音樂之路,即使沒有打開收音機, 現在駕駛也能於開車長途旅行時享受音樂。
音樂之路實際上是如何運作的呢?它和車輪駛經那些路面上被切 割出的溝槽時產生的振動有關。溝槽之間的距離愈近,音調就愈高。另 一方面,那些相距較遠的溝槽會產生較低的聲音。第一條音樂之路於 1995 年被建在丹麥吉林。該路發出的曲調是一組簡單的 F 大調音符。
為了產生理想的效果,駕駛必須以特定速度駛經溝槽。這和黑膠 唱片的概念類似,它每分鐘必須旋轉四十五或三十三次。路標常會顯 示理想的車速,且駕駛也必須確保他們正面駛經溝槽。
