Hi!
Anybody heard of such a thing?

On certain roads with pillars, trees, tunnels at the side and with
certain distances (pillar-street and pillar-pillar) and a certain speed
there are rythmic noises if a car passes by. Its a negative phenomenon
for the car drivers as well as for the residents.

The frequences and amplitudes should be calculated easily to avoid them.

Are there any existing projects to create music with it? A so called
"music wall" (of course in areas without residents). The americans and
french are often very playful with road, bridge and tunnel projects...

Maybe somebody knows of anything.
Thanks.
