In the case of sound, these waves of reflected energy are called " echoes ". Echoes and other sounds can convey spatial information that is comparable in many respects to that conveyed by light.
Echoes make information available about the nature and arrangement of objects and environmental features such as overhangs, walls, doorways and recesses, poles, ascending curbs and steps, planter boxes, pedestrians, fire hydrants, parked or moving vehicles, trees and other foliage, and much more.
Echoes can give detailed information about location where objects are , dimension how big they are and their general shape , and density how solid they are.
Dimension refers to the object's height tall or short and breadth wide or narrow. By understanding the interrelationships of these qualities, much can be perceived about the nature of an object or multiple objects.
For example, an object that is tall and narrow may be recognized quickly as a pole. An object that is tall and narrow near the bottom while broad near the top would be a tree.
Something that is tall and very broad registers as a wall or building. Something that is broad and tall in the middle, while being shorter at either end may be identified as a parked car.
An object that is low and broad may be a planter, retaining wall, or curb. And finally, something that starts out close and very low but recedes into the distance as it gets higher is a set of steps.
Awareness of density adds richness and complexity to one's available information. For instance, an object that is low and solid may be recognized as a table, while something low and sparse sounds like a bush; but an object that is tall and broad and very sparse is probably a fence.
Some blind people are skilled at echolocating silent objects simply by producing mouth clicks and listening to the returning echoes, for example Ben Underwood.
Although few studies have been performed on the neural basis of human echolocation, those studies report activation of primary visual cortex during echolocation in blind expert echolocators.
In a study by Thaler and colleagues,  the researchers first made recordings of the clicks and their very faint echoes using tiny microphones placed in the ears of the blind echolocators as they stood outside and tried to identify different objects such as a car, a flag pole, and a tree.
The researchers then played the recorded sounds back to the echolocators while their brain activity was being measured using functional magnetic resonance imaging.
Remarkably, when the echolocation recordings were played back to the blind experts, not only did they perceive the objects based on the echoes, but they also showed activity in those areas of their brain that normally process visual information in sighted people, primarily primary visual cortex or V1.
This result is surprising, as visual areas, as their names suggest, are only active during visual tasks. The brain areas that process auditory information were no more activated by sound recordings of outdoor scenes containing echoes than they were by sound recordings of outdoor scenes with the echoes removed.
Importantly, when the same experiment was carried out with sighted people who did not echolocate, these individuals could not perceive the objects and there was no echo-related activity anywhere in the brain.
This suggests that the cortex of blind echolocators is plastic and reorganizes such that primary visual cortex, rather than any auditory area, becomes involved in the computation of echolocation tasks.
Despite this evidence, the extent to which activation in the visual cortex in blind echolocators contributes to echolocation abilities is unclear.
This would suggest that sighted individuals use areas beyond visual cortex for echolocation. Echolocation has been further developed by Daniel Kish, who works with the blind through the non-profit organization World Access for the Blind.
He learned to make palatal clicks with his tongue when he was still a child—and now trains other blind people in the use of echolocation and in what he calls "Perceptual Mobility".
Kish reports that "The sense of imagery is very rich for an experienced user. One can get a sense of beauty or starkness or whatever—from sound as well as echo.
Thomas Tajo was born in the remote Himalayan village of Chayang Tajo in the state of Arunachal Pradesh in the north-east India and became blind around the age of 7 or 8 due to optic nerve atrophy.
Tajo taught himself to echolocate. Today he lives in Belgium and works with Visioneers or World Access to impart independent navigational skills to blind individuals across the world.
Tajo is also an independent researcher. He researches the cultural and biological evolutionary history of the senses and presents his findings to the scientific conferences around the world.

From childhood on, Ben used this clicking -- called echolocation -- to "see" the world. In , a few years after appearing on "The Oprah Show," Ben died from his retinal cancer.

As shown in the documentary video, Ben Underwood used echolocation technique to help his navigation, and even without eyes, he could accomplish feats like running, playing basketball, riding a bicycle, skateboarding and even fight a karate match.
Human echolocation is the ability of humans to detect objects in their surroundings by sensing the echoes from those objects. They do this by actively creating sounds — for example, by tapping their canes, stomping their foot lightly or even making clicking noises with their mouths, like in the present case of Ben.
Many species like bats and dolphins use this echolocation technique to get around, and many blind people listen for echoes to certain extent.1/20/ · Ben Underwood, 16, passed away at his home in Elk Grove.
