We know that bats and whales use echolocation to find the right path. Recently, we have learned that we humans also can visualize their environment by emitting certain sounds with his mouth.
In the new study exposed the details of the world's first description of human echolocation , including its acoustic characteristics and spatial extent of the sounds issued by mouth.
"Understanding the acoustic mechanisms will help us better understand what information we used our brains to eholotsira" explains Laure Thaler of the University of Durham.
Although seeing the world through sound is not something that people have a natural ability, studies have shown that those who do not see may develop with practice senses , similar to bats. The latest data suggest that there is no need for people to have trouble seeing to learn echolocation. Scientists have found that people with normal vision can detect the size of virtual rooms using the technique of echolocation.
