when you produce sound, and it hits a barrier, and reflect back. echo is hearing the sound again after the vanish of the original sound. you can only hear it if these two reasons are satisfied:
1) the barrier should be wide (large) enough.
2) distance between source of sound ( the observer) and the barrier is 17 meters or more.

The easiest answer is that you hear echo by your own ears. DONE BY AHMED HUSSIEN and i thank mr. Ahmed my physics teacher... because without him i wouldn't of had these information....
