I’m assuming you meant “yes we see 3d surfaces in 2d” to be consistent with the parent comment? Also, I’m impressed that dolphins have that ability. How does projecting them to each other work biologically? Do they somehow encode what they see as sound (less lossily than humans do)?
I'd imagine they work directly in the frequency domain. They don't "see with sound", they'll just hear nested spheres or whatever.
This suggests to me that humans could harness the same audio phenomena.
Some people can. There's a few cases of blind humans who can echolocate to some degree of accuracy (enough to ride a skateboard in one case).
