Humans are surprisingly good at echolocation.
For example, with your eyes closed, hold your arm out with your palm facing your face and make a droning noise while bringing your palm towards your face.
Now try making a 'click' noise while facing inches away from a wall. Now try the 'click' in a hallway.
There's a blind guy named Daniel Kish who rides a bike using echolocation. He teaches this stuff to people through an organization called world access for the blind.
I would also like to hear like a bat.
That's cool
