Wired covers the possibility of teaching humans to use echolocation:

Most animals that use echolocation have organs that are specifically adapted to emit and receive sonar signals, but we humans have to rely on our rather clumsy mouth and ears. For instance, while dolphins use a special structure in their nose to generate up to 200 clicks per second, people can make only three or four clicks per second.

echolocateBy studying the physical properties of the many different sounds the human mouth can produce, the Spanish researchers hope to maximize the power of human echolocation. In their latest study, published in a recent issue of the journal Acta Acustica united with Acustica, the group taught 10 of their students and colleagues to use basic echolocation. Then they compared different noises and clicks to determine the best type of sound for ?seeing? your surroundings.
Interesting, if not for everyone.
