The "Music Highway" was proposed by a Japanese named Shizuo Shinoda. He accidentally used a bulldozer to grind some construction debris into the road. When he drove past here again, he unexpectedly heard various sounds coming from under the car. So how does "Music Highway" sound? Let Zhongda Consulting help you answer the mystery of the "Music Highway".

Description

Many car owners like to listen to the radio while driving, or prepare a few of their favorite CDs in the car to enjoy music while relieving the fatigue of driving. But have you ever thought about listening to the wonderful music coming from the road? An invention by Japanese engineers will turn dreams into reality.

There are two Melody Roads, one in Gunma and one in Wakayama. Both roads are marked with prominent colorful musical notation. When the driver passes by here, as long as he keeps the speed at 40 kilometers per hour, Melody Road can play the Japanese song "见上げてごらん夜の星を"! Amazing, right? In fact, its principle is very simple. When a car passes through a groove on the road at a certain speed (commonly known as a washboard road~), the friction between the tire and the ground will make a specific sound. The height of this sound is consistent with the groove. It is related to the spacing between them. The smaller the spacing, the higher the pitch. In other words, as long as we have enough patience to create enough grooves on the road, we can also let China's Chang'an Street play "Hee Swah Swish".

How it works

How Music Highway works is simple. Divide the tracks left by the car on the ground into several segments according to certain standards, and set small deceleration ridges or ground markings on the ground. When a car drives over, a rumble occurs in the space between the car's chassis and the road. According to the distance of the driving track, when the car drives by, it can produce music and melodies with different levels and patterns, so that a piece of music can be played. However, people must control the driving speed at 45 kilometers to enjoy wonderful music. If it is too fast or too slow, it will produce the effect of fast or slow playback.

Creativity comes from life. The idea of ??"Music Highway" was originally proposed by a man named Shizuo Jiaoda. He accidentally used a bulldozer to crush some construction debris into the road. When he drove past here again, he unexpectedly heard various sounds coming from under the car. Later, engineers in Sapporo, Japan, refined Touta's design and developed the new technology, including using infrared light to detect uneven and dangerous road surfaces. If you want to get a beautiful melody, people must close the car windows and control the speed at 45 kilometers per hour to let the "Music Highway" sing to your heart's content. Driving faster will produce a fast-forward sound, while speeds as low as 20 kilometers per hour will produce a slow-forward sound.

Application Cases

Three "music highways" have been born in central and northern Japan. The pavement of this kind of highway is marked with musical symbols of different colors. When a car drives in, the highway will make a pleasant sound.

China’s first music highway was built in an ecological community in Changge New District, Henan Province. This two-way road combines physics, acoustics, and music-related technologies. When a vehicle passes by at a constant speed, the air impact sound generated when the tires contact the seams in the road, and the micro-vibrations generated when passing through the grooves, combine into music and melody with different levels and rhythms, playing corresponding music.

Practical applications need to be improved

Since people have different tastes, their preferences for music are of course difficult to agree on. But as far as current technology is concerned, "Music Highway" can only play a fixed piece of music according to the designed pattern. At the same time, getting a beautiful melody is not an easy task. People must close their car windows and control the speed at 45 kilometers per hour to let the "Music Highway" sing to their heart's content. If you drive faster, it will produce a fast-forward sound, and if the speed is less than 20 kilometers per hour, it will produce a slow-forward sound. For those passionate rock enthusiasts who want to pursue dynamic music and people who advocate music DIY, the practical application of "music highway" is far from meeting their needs.

The above is the introduction provided by Construction Network on the working principle and application cases of "Music Highway".
