Japan's Musical Road
>> Friday, November 16, 2007
Engineers in Japan were able to make music from one of their roads by virtue of vehicle tires rolling over different sets of grooves.
The musical notes you see on the road are simply warnings that just up ahead you'll start to hear music from your tires. The music is made from a series of grooves cut perpendicular to the road. Different pitches are created by cutting the gooves closer or further apart.
The result is a cacophony of tires humming. Apparently, 28mph is the ideal speed to hear for a musical interlude.

This 'musical road' idea, like many others, was copied by Japan from the good ol' USA - with a slight difference. Stateside, they ran trials of a hard-shoulder 'rumble strip'with different pitch grooves to make music from tyre hum - same concept, but pitched for the 50mph speed limit. The tune selected was "Nearer, my God, to thee"...........
