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. The grooves on the road are designed and cut according to the tunes of different music. Different groove widths, groove spacing and groove depths symbolize different notes. The sound of the tire contacting the ground and the impact with the air becomes a rhythmic sound. sound.

"Imaginatively speaking, the grooved road is a 'record' and the car tire is a 'stylus'. When the two are combined together, they can 'sing' like a gramophone. When the car is traveling at a certain speed When passing through this road, it will sing specific music. Isn't it amazing? It creates specific grooves on the road, so that when the vehicle passes by, it will vibrate and emit a specific tone. For example, Mi in C major is. 330

Hz, so if a groove is placed every 61 millimeters on the road, and when the car drives by at a speed of 72 kilometers per hour, it can make the sound of Mi

We. In 2013, the concept and plan of raised music pavement was proposed, which is exactly the opposite of the Japanese groove principle. The project was completed and the corresponding technology development and experimental verification work was completed, and the raised music pavement technology was patented. It replaces the grooved music pavement and avoids damage to the existing pavement. It has the advantages of clear sound, fast construction, replaceability, cleanability, and easy maintenance. It is suitable for roads with speeds in the range of 50km/h~70km/h. The general construction period In about 10 days, the music road can be changed or erased as needed without damaging the existing road surface.

Such a music road can bring a sense of novelty to tourists. In addition, it can also help control vehicle speeds. . Because you can only hear the correct music when you pass at a certain speed. When the speed is too slow, not only will the music become slower, but the tone of the music will be lower; The pitch will also be higher.
