What’s the deal? What is an Echo?
An Echo occurs when the sound from your voice bounces off of an object and comes back to you. That’s why if you ever catch yourself in a cave, screaming “Hello!”, you’ll hear your voice come back to you in the form of an Echo.
The closer the object, the louder the Echo. When the sound waves lose their energy, the Echo fades.
Next time you’re outside, give it a try. Of course, make sure you don’t scream at people! Look for open spaces. Ideally.
