Creating echolocation for humans

1 (training) While blindfolded.
-Having a person at a fixed distance make noise at a random fixed distance with an object or a speaker. The person then has to point towards that person.
-Having a person at changing distances make noice at random spots with an object or a speaker. The person then has to point towards that person. 
-Having a person walk around and and having the person point at him by the noise of his steps.
-Having small speakers all around a person  and having the person point at a speaker that made the noise. The speakers should also be above him etc.

2
- First making noise with the fingers, mouth or with a speaker, without something around. And then going close to a wall and making the noise. And hearing the difference.
-Same as the above but try with metalic and wooden barriers etc.
-Blindfolded go closer to a wall while making the noise and detect when the wall is close, going from wall to wall.

Warning: Safety is of some importance, don't fall etc.
