A Californian sound physicist reveals a mystery that existed long ago around the pyramids built by the Mayans. The sound at the foot of these pyramids gives rise to a special echo that local tourists show as curiosity.
Physicist David Lubman has investigated this phenomenon and given it a simple physical explanation based on the shape of the steps of the pyramid. When sonar occurs echo in each level of the pyramid, but in each level a curious effect occurs at every moment. In Lubman's opinion, this phenomenon was used to mimic the sound of the sacred rooster and probably thanks to an unexpected discovery.
