Have you ever tried? I find the article's description a bit too advanced for a first try. I have personally had success finding walls or large furniture after only a couple minutes of very slowly walking around a room and clicking my tongue (higher pitched) with my eyes closed. True, I probably won't ever be able to ride a bike, but it's sufficient to quickly test out basic echolocation. I have done many trials with friends and everyone is able to hear at least a subtle difference when standing directly in front of a wall as opposed to a few feet away.

Agreed. I taught myself basic echo location several months back after reading about Daniel Kish and being curious.

It doesn't need any external equipment to get the basics. To start out simply, just close your eyes in a (very) dark room and get the hang of the different sounds when a wall is close in front of you (couple inches) vs not.

Once you can clearly detect that difference, start extending from there. It definitely works ok.

I was referring to full blown echolocation as with Ben Underwood, not "basic echolocation".
