I'm not Ashley, but I can tell you what echolation is.

Just like light, sound bounces off of, or is absorbed by, objects and 
then bounces back into our ears. Echolocation takes advantage of this 
in the same way sight does. The main difference is that, for the most 
part, there is an outside light source apart from the seer. In this 
case, the listener generally produces the sound that will bounce off of 
objects. Cane taps are usually sufficient. The quality of the sound 
tells the listener if it has been absorbed or bounced back and to what 
extent. Those who get good at it can even tell the shapes of the 
objects they listen to, where they are exactly located, and how far 
away they are. A listener can also gain this kind of information by 
using outside sound sources and listening to how those sounds bounce 
off of the objects they're close to.

The average echolocation user can generally tell where trees and bushes 
are, people, large buildings, glass windows and doors, metalic objects 
like cars, curbs, and other very noticeable things like that. Some of 
us can tell smaller objects such as street poles, planters, and other 
things of the sort. Echolocation takes practice. I had to study it in 
Louisiana (I studied under Roland Allen, who is quite adept at 
echolocation). I would love to study under Dan Kish, the king of 
echolocation, however.

Respectfully,
Jedi
