I vaguely recollect watching a documentary years ago, which had a blind kid who'd taught himself echolocation using clicking noises that he made with his mouth. I remember that some grownups were trying to discourage him from relying on that and to use a stick instead, but he wasn't keen. The echolocation was giving him more information it seemed like.
