entertain themselves, after engineers in Japan developed a musical road surface.
A team from the Hokkaido Industrial Research Institute has built a number of "melody roads",
which use cars as tuning forks(音叉)to play music as they travel.
The concept works by using grooves(凹槽).They are cut at very specific intervals in the road
surface. The melody road uses the spaces between to create different notes.
Depending on how far apart the grooves are, a car moving over them will produce a series of
high or low notes, and designers are able to create a distinct tune.
Patent documents for the design describe it as notches(刻痕)"formed in a road surface so as
to play a melody without producing simple sound or rhythm and reproduce melodylike tones".
There are three musical strips in central and northern Japan-one of which plays the tune of a
Japanese pop song. Reports say the system was invented by Shizuo Shinoda.He scraped some
markings into a road with a bulldozer(推土机)before driving over them and found that they helped
to produce all kinds of tones.
The optimal speed for melody road is 44 kph,but people say it is not always easy to get the
intended sound.
"You need to keep the car windows closed to hear well,"wrote one Japanese blogger."Driving
too fast will sound like playing fast forward, while driving around 12 mph[20 km/h]has a slowmotion
effect, making you almost carsick."
