This guy is the type of guy that would survive if he was in bird box

[setsunaimpacto]

This is the only guy who can complete a mirror house with bumping their face in anything.

[Concetta]

It’s amazing how the body is designed to adapt when it loses one of its senses.

[davidca]

this has always amazed me, its remarkable how good his ears became to be able to distinguish echo'd sound to location and map it in his brain.

[maksillorenzo]

This dude can “see” density- that’s so freaking cool

[CHAD-RYAN]

Imagine if i clicked back at him, he wouId be like wtf is going on.

[TheWtfnonamez]

I worked with a guy who used to do this. I first spotted him doing it when the lift doors opened. He could tell if anyone else was in the lift ahead of him by the sound that bounced back.

[intotheunknown]

This man is the definition of amazing.

[octagontowers]

No words can define how extraordinary this guy is... Woooow!

[deniedprosperity]

People underestimate the power of sound and hearing. I felt this as a kid, when I was behind a theater with a blindfold on. I was behind this veil, and every time I talked I hear a sound, a resonating one, I could picture exactly where it was coming from and what was happening based just on the acoustics. Whether it was people talking in the lobby, music playing on stage, or other noises backstage, I had a whole scene painted in my mind from audio alone. It was amazing how much information you can perceive just through listening. Ever since then, I've been fascinated by how we interpret the world through our sense of sound. There's so much packed into what reaches our ears. I think if more people paid attention to listening actively, they'd be surprised what they can discover about their surroundings and even other people just through picking up on the auditory details around them. This man, is telling the truth. You can train yourself to adjust to a certain degree of technique without feeling the need to just sit there and let yourself die out of boredom. I'm not blind, but everytime I walk, I close my eyes and everytime, i could picture what is beneath me, what type of vehicle is moving on the on other side of my ear, it is phenomenal. And if you think I walk at a few hundred meters, you'd be wrong. I know exactly what the layout of my hometown is therefore it makes it so much easier for me to simply walk all the way home without opening a single eye. The sound of my footsteps never stop echoing bottom to top, that I genuinely know what shape the ground is, a rocky upward slope, a straight but bumpy road, it made me realize that I have also honed a the technique this man uses.

[TDDY]

There is a boy that also did this, unfortunately he passed away

[some_guy]

This blows my mind, one of the most amazing things I've ever seen.

[RazEdits]

Does he fight crime at night? He's a ninja :D

[haleyc.]

Aesop Rock uses a clip of the first line of this video as the opening to his song "Klutz"!!!

[tedrichardson]

I showed this to my students and they were amazed.

[SenulHettiarachchi]

they are the real people who claim the success whatever bad happens in their lives

[cashmoney]

did anyone else try too shh and click at your device to see if you could do it?

[KonradPawlak_]

Imagine playing the last of us, and 10 minutes later you hear this in school

[mbsoysal]

I have a theory on why clicking sound works for him. In engineering, in signals and systems topic to be more specific, there is a concept called "impulse response". Basically what you do is that you apply an impulse (an infinitely short pulse) to the system and see how the system responds to it. This way you can mathematically model the system. This person very cleverly figured that out with a clicking sound. He applies a short sound pulse and identifies the system around him. I think it helps that the hearing part of our brain can do a frequency analysis. This video brought me back to my signals and systems course days :)

I went to school with Danny. He was amazing to watch him get around without a cane. He's a really cool dude as well.
