Melody Road – speed control using music – best heard at 28 mph
November 11th, 2007

I was intrigued by a report coming out of Japan about Melody Road

“…We had no reason to offer any further proof that Japan is the unquestionable winner when it comes to wacky inventions, but the Melody Road convinces us our judgment is completely accurate. The Melody Road will allow a car passing above it to play a simple tune, which is made audible by ridges on the road’s surface. The pitch of the note created is increased by increasing the frequency of the ridges, and the opposite is also true.

“…The optimum speed for the best sound reproduction is a shockingly slow 28 mph. At that speed, a little noise will be needed to keep the driver/passengers alive awake. 

…… The Melody Road has been incorporated in three locations throughout Japan, including Hokkaido, Wakayama and Gunma. [Techeblog]
