Amazing. I actually lost my eyesight about 3-4 years ago, for almost 2 months. All i could see was white light, and everything was blurry. I had to get treated by a delaware lasic surgeon. Long story short... I NEVER thought i would be like this kid. In that short of a period I had already given up.
I give him credit.... he's awesome with that clicking.
Umm.. but this last part freaked me out a little.....
The Mystery of Sonar Boy
Bats use echolocation. Can people use it, too?

In early September, a 14-year-old kid with empty eye sockets strode on stage for a taping of the talk show Ellen. "I'm not blind," he told the host to wild applause, "I just can't see." The story seemed lifted from the pages of a comic book: At the age of 3, Ben Underwood lost his eyes to retinal cancer. Three years later, he discovered that he could sense objects around him by making little clicking noises with his tongue and then listening for the echoes. Now, he uses these clicks to find doorways and locate cars on the street. That's right—he navigates with sonar.
The Sonar Boy had been on the CBS Evening News a few days earlier, Rollerblading, playing Foosball, and throwing pillows at his sisters. But his big break came back in July, when People magazine ran a five-page profile that dubbed him "The Boy Who Sees With Sound." "Ben pushes the limits of human perception," one expert told People. Watch the clips of him on YouTube and it's hard to disagree—if this kid's not a prodigy, he's a brilliant fraud.
Ben Underwood's echolocation isn't a hoax, but it's not an unexplained mystery, either. Ben really can sense nearby objects with reflected sound waves. But so can you. If Sonar Boy is some kind of superhero, then we're a nation of Daredevils.
Go ahead and try out the skill you never knew you had. First, close your eyes and put on a blindfold, and then ask a friend to move a frying pan forward and backward in front of your face. Now start making noises—any noises you want. You can click your tongue like Sonar Boy, or you can whistle, or you can sing a scale. With a little bit of practice, you'll be able to tell when the pan is close to you and when it's not.
You won't even know you're hearing an echo. In general, you'll only catch your sound repeated if it bounces off something far away: First you'd hear your own voice, then a pause, and then the echo of your voice returning to your ear. When you bounce a noise off of something that's close to your face—like the frying pan—it zips back so fast that it overlaps with the original sound. The brain hears the combination of the two as something like an alteration in pitch. So, you may not hear a discrete echo when you whistle at a frying pan, but your ears can pick up the difference.
Anyone can echolocate, but blind people happen to be especially good at it. (And Ben Underwood seems to be even better than most blind people.) You don't even have to make your own clicks or whistles; some people use the echoes from ambient noise, or even from their own footsteps, to sense obstacles. With trained ears, you might be able to tell when you're passing an open door in a hallway by the way the sound "opens up" around you.
For centuries, scientists have been working on the question of how blind people compensate for their loss of vision. Diderot's "Letter on the Blind" from 1749 described an "amazing ability" to navigate in the absence of sight, which later became known as "facial vision." (Practitioners described a sensation of feeling objects or barriers on the skin of their faces.) The notion that this spatial sense arose from touch and not sound was only disproved in the 1940s.
At the time, no one knew exactly how a person might "hear" an object. Echolocation was still a new concept—the term had been coined a few years before, and its use by bats had only been documented in 1938. Research into sonar exploded in the early years of the Cold War, due to its apparent military applications. But the notion wasn't systematically applied to blind people—and "facial vision"—until a notorious psychologist named Winthrop Kellogg began his human-echolocation research program around the time of the Cuban Missile Crisis.
Kellogg was best known for a controversial, Depression-era experiment in which he raised a baby chimpanzee alongside his own infant son. (Click here for a movie he made of the two babies.) But he'd also spent years showing that porpoises, like bats, use reflected sound waves to navigate their environment. In 1962, he published his first major study showing the ability in humans. Using a setup not much different than the frying-pan test described above, Kellogg was able to prove that people—and especially blind people—can use self-generated noises to locate discs of various sizes and materials. (His subjects could even distinguish between discs covered in velvet and denim.)
Of course, the human echolocation he demonstrated wasn't nearly as sharp as that of other animals. Bats, for example, emit and hear sounds at very high frequencies, which allows them to track tiny insects in midflight. Some bats even compensate for the Doppler effect as they swoop toward their prey and cancel out the interfering sound of their own fluttering wings. People couldn't do any of this fine-scale discrimination, but Kellogg showed that they could use sound to sense a world of blobs and textures.
Meanwhile, the same postwar period had seen the development of another branch of research on people who were visually impaired. Staffers at military hospitals spent much of the 1940s figuring out how to teach orientation and mobility skills to blinded World War II veterans. Aspects of the "O&M" program they developed—which made use of long canes and reflected sound—are still in use today. Earlier this year, a panel of O&M experts included echolocation on a list of skills that should be taught to every blind student.
Everyone agrees that sonar can be useful, but the extent to which it should be relied upon remains a controversial issue in O&M. A few specialists, like Dan Kish (the expert quoted in People), believe that echolocation can be used as a primary mode of getting around. But it's more often taught as a secondary skill—to be employed only in conjunction with a cane or guide dog. (A specialist might suggest tapping the end of a metal-tipped cane for sonar feedback.)
Many O&M specialists believe that even the most talented echolocaters would be better off—that is, safer—with a more conventional mode of navigation. Even Ben Underwood's own specialist worries over his reliance on clicks. "It would be much safer for him to use a cane," the specialist told the Sacramento Bee back in May. For all his skill, the specialist added, Ben still runs into people and trees and walls.
The story of Ben Underwood propagates another idea that advocates for blind people find uncomfortable. They've been working for years to dispel the long-standing "myth" that people without sight can compensate for their deficit with superhuman hearing or touch. (Some people who are blind don't hear well at all, and the ones who do would rather not be thought of as freaks of nature.) And now here comes the amazing Sonar Boy, the Boy Who Sees With Sound.
Did Ben get to be so good at echolocation because of some extraordinary brain development? Or is it just that he's been practicing in his every waking minute for eight years? Kellogg's experiments couldn't distinguish between the two. Even today, scientists don't have a handle on the extent to which blind people are better at using their ears.
If people who are blind really do have exceptional hearing, it's not easy to demonstrate it in the lab. It wasn't until the late 1990s that blind test subjects were shown to be better at localizing sounds, and even then it was only for sounds that originated from off to the side. (Subsequent work implied that blind people are worse at localizing sounds from directly ahead of them.) Other experiments suggest that the blind may be slightly better than average at discriminating pitch and that their ears might be a bit more sensitive to echo cues. Sensory compensation may not be a myth, but it's not a miracle, either.
Just like the Sonar Boy. We were all amazed by his ability to sense objects with tongue clicks, but we only believed in him because he's blind. We knew that humans can't use sonar, but we were just as certain that blindness can make you superhuman. That pair of misconceptions was enough to make Ben Underwood a celebrity.

A Remarkable Blind Teen
John Blackstone reports on a California teenager who is blind and overcomes his disability by experiencing life with all his other senses. | Share
(CBS) In a pillow fight, 14-year-old Ben Underwood can deliver a dead-on shot; in foosball, he's a determined competitor; when a video game is going, his fingers fly. And when he is on his skates, he's fearless. For most teenagers, it's nothing remarkable. But Ben is blind.
As CBS News correspondent John Blackstone found out, Ben uses sound to find his way around. To walk down the street with Ben is to be amazed at what he can see with his "ears."
Ben makes clicking sounds and while walking down a sidewalk can even determine the difference between a fire hydrant and a trash can.
Ben was just 2 years old when cancer claimed his eyes. Both were surgically removed. It was a day of heartbreak for his mother, Aquanetta Gordon.
"And he woke up from that surgery and Ben said, 'Mom, I can't see any more, I can't see any more,'" she recalls. "And I said 'You can't use your eyes but you've got your nose, and your ears and your mouth.'"
From that day on, Ben has used his hearing, his sense of touch, his sense of smell to conquer a world of darkness. And he is good: while going for a walk with Blackstone, Ben deftly stepped around a fallen trash can on the sidewalk.
Somehow, Ben has mastered echolocation. It's the same way dolphins get around, bouncing sound waves to figure out where they are.
On a trip to Sea World a few weeks ago, Ben found that he and the dolphins shared an amazing talent.
Out of the water, it becomes easy to forget that Ben is blind, as Blackstone found out when he was beaten 5-2 in a friendly match of foosball.
Playing video games with his brother Isaiah, in the assault of noise, Ben can figure out everything that's happening just by listening.
How does he manage to compete? "Because they got different voices," Ben explains.
"Nobody is going to tell him that there is an impossibility for him. 'Cause there are none," says his mom.
"This mom ought to be teaching a course on how do you raise a kid who can't see well," says Kaiser-Permanente ophthalmologist Dr. James Ruben.
He says Aquanetta has done exactly the right thing with Ben: never being overprotective and never putting limits on him. "You know, I think the real story here is not, is not his talents, but his attitude. And attitude is what it's really about."
Aquanetta agrees. "We have to give our kids confidence. We give them pride. Empower him with who he is, and be proud of who you are, no matter what!" she says.
"'There's nothing you can't do..." she adds. "And that's the attitude, you know what I'm saying? That's what I want to give him."
Watching him in action, it seems clear that Ben really can do anything.

So, basically, he's getting attention for doing something that most people can do anyway, but only because he's gotten really good at it. Like an outstanding sports star, or a physicist.

See that is the silliest thing you have ever said, This boy deservers alot more attention than Rossi, or hayden, he certainly deserves more attention than any celeberty on earth, what he does, despite what you may think, is truly amazing.
Scientists Cannot discredit him so now its "everyone has this ability" really? So how come no other blind people are running around doing it? Will they, sure someday they will. But for now, he is the big wonder, and wonder he is.
You say everyone has this ability, that may be true, I believe most people have abilities that your great scientists like Randi say do not exist, like dowsing, or maybe ESP, but since science can fully discredit it, it doesnt exist becouse its random, but I say sonar is done in nature, and so do animals find water, nothing amazing there is it, but if a human does, he is a fool and misguided.
Quit picking and choosing what can and cannot be done.

Again, it is based on known science, namely echolocation, and is therefore not "paranormal" in any way. Is he gifted, sure. He has developed a skill to the point of near perfection, and far better than anyone else. Blind people are better at it than people with sight, and he is better at it that most blind people. Its the same as comparing someone who's never ridden a motorcycle (sighted people), to people that ride daily (sightless people) to Valentino (this kid).
Dowsing and ESP are not based on any known science. It's not that science can't discredit it, it's that those that claim to do it can't prove it. The burden of proof is on the dowser. No one is picking a choosing what can't be done. He can do it because he has proved it to scientists. You can't dowse because you haven't.

You havent read the other threads obviously, I dowse all the time. So do millions of other people, The reason science discredits it is simply becouse they do not yet understand it, in time, they will.

So... who cares if that's the only reason he is getting attention. He's probably missed out on a lot over the years because he was robbed of his eyes... let him have his moment.

I'm relatively sure the boy is not reading my posts and, thus, I am not robbing him of his moment.

For doing what anyone with hearing can do to some extent, only better? Not really.

Other blind people are doing it. Sighted people are doing it as well, though they tend not to notice because they depend more on their sight.
Echolocation is an innate ability in those who can hear, and depends both on noises you make and ambient noise. Documents and Video
