Still more evidence that Daredevil's superpower isn't being able to navigate using echolocation, but to be able to take a beating (which he inherited from his father).
"The researchers trained 14 sighted and 12 blind people for between two and three hours twice a week over 10 weeks. They started by teaching participants to produce mouth clicks, then trained them on three tasks. The first two involved judging the size or orientation of objects. The third involved navigating virtual mazes, which participants moved through with the help of simulated click-plus-echo sounds tied to their positions."
This was kind of cool https://www.youtube.com/watch?v=nsg81Tn3s28
I didn't like the first wall example because the clicking cadence changes, but the field and trees were very clear
