🏍️ — Singing exhaust pipe !

The idea is quite simple : placing diapason on exhaust pipes to get singing motorcycles.

A. As visible on the original board (below) you could place several of them along the exhaust pipe shape, attached in one or two points depending on the thickness of the joint.

B. The jointed diapason height, width and hollowed cavities can help selecting a precise resonance frequency.

C. Selected resonance frequencies for the jointed diapasons may vary thanks to speed, hence changing during accelerations or even help the driver know it has reached a particular speed limit with a chosen frequency (like 130 km / h).

D. Positives effects :

• • Less overall hearing loss, fatigue or damage (both for drivers and pedestrians).

  • Less sleep perturbation, cardiovascular and cognitive troubles, etc.

  • Less sonore pollution (which would produce positive effects both for the living and the biosphere).

End note : this idea applies to all vehicles having exhaust pipes.
