Shhhh, quiet please! Listen.

Can you hear the echo of the water bouncing off the rock?

Stand in front of this boulder, and listen to the echo of the water. This stone surface amplifies sound, just like ancient Mayan ball courts. In the Chichen Itza ball court in Mexico, a whisper can be heard clearly from 500 feet away.
