Humans capable of using echolocation

Producing certain kinds of tongue clicks helps people to identify objects around them without seeing them - a useful tool for the blind, but also for people lost in fog or in the dark. By using echolocation, it is possible to measure the distance of an object based on the time that elapses between the emission of a sound wave and an echo being received.

"In certain circumstances, we humans could rival bats in our echolocation or biosonar capacity," claimed Juan Antonio Martínez, lead author of the study and a researcher at the Superior Polytechnic School of the UAH.
