First Time in the World, researchers created an impression of a submerged human recorded by a dolphin’s echolocation.

A team of researchers used an imaging system known as a Cymascope the system, developed by John Stuart Reid (who also assisted with the project), made it possible to record and isolate dolphin echolocation sounds directed onto specific objects, and then create 2D images from those sounds. A computer then converted those images into 3D, which allowed the researchers to 3D-print robust, real-world models.
  “We’ve been working on dolphin communication for more than a decade.When we discovered that dolphins not exposed to the echolocation experiment could identify objects from recorded dolphin sounds with 92% accuracy, we began to look for a way for to see what was in those sounds.”

For the experiment, a feminine dolphin named Amaya directed her sonar beams at a submerged diver, whereas a hydrophone captured the following echos. To keep away from added “noise,” the diver, Jim McDonough, swam and not using a respiration equipment to ensure no bubbles would adversely have an effect on the outcomes. As Amaya scanned McDonough together with her excessive frequency sound beam, the CymaScope imprinted sonic vibrations inside the water medium.
Along with the diver, the researchers additionally had Amaya direct her sonar at a flowerpot, a dice, and a plastic “+” image.
“We have been thrilled by the primary profitable print of a dice by the sensible staff at 3D Techniques,” stated Kassewitz. “However seeing the 3D print of a human being left us all speechless. For the primary time ever, we could also be holding in our palms a glimpse into what cetaceans see with sound. Almost each experiment is bringing us extra pictures with extra element.”
