This phenomenon is called an echo, which has its origins in the Greek ekho, meaning “sound.” An echo happens when a sound wave reflects off a surface, such as the water at the bottom of a well, and the sound is repeated back to you.

How is an echo created?
An echo is made by sound waves bouncing off a hard surface. ... The sound waves are typically absorbed before they hit something hard that they can bounce off of. But sometimes there still isn't an echo, even if you're in a place where there are no soft things to absorb the sound waves.
