Is there a specific question? Otherwise a google search would be more useful.

You can do both. A google search on en.wikipedia.org

Type this in the google search box:

There is more to echolocation than just determining distance. There is also horizontal direction and azimuth. Bats can accurately locate prey in the dark. Some insects can accurately locate prey (or mates) by determining direction of sound. Female crickets chirp so male crickets can find them using a clever directional hearing system.

So can humans. Close your eyes and have someone pick someplace in the room to stand after your eyes are close and talk to you; you'll be able to find them based on direction of sound. Of course that's not echolocation, but just directional hearing.

The term echolocation is pretty self-explanatory in terms of a definition, though.
