Visual feedback to sonar clicks
The wildlife park Kolmården in Norrköping, Sweden, asked for a device that could visually feedback how dolphins use their ultrasound signals while echolocating objects. By recording the sound from the dolphin, process the sound and then create a visual feedback by having LED's flash in different frequencies, depending on the distance between dolphin and device. The purpose of the device is havVisual response to dolphin echolocation It is well known that dolphins use echolocation but how about watching what actually happens? A device that shows the audience some of the information contained within the emitted ultrasonic waves. It is a small fish look-alike device that is created to simulate how the dolphins behave while hunting. By picking up the echolocation signals sent out from the
