Re-echo for Dummies

Re-echo is a word that we use to describe a sound or a noise that bounces back to us after it hits a hard surface, like an echo. Have you ever shouted or clapped your hands in a big empty room and then heard the sound come back to you? That's kind of what re-echo means - it's like the sound is coming back to us for a second time, repeating itself.

Imagine you're in a big open field and you shout, "Hello!" The sound of your voice travels through the air, but when it reaches a tall mountain, it bounces off and comes back to you. So instead of hearing the sound just once, you hear it twice - once when you shout and again when it bounces back. That bouncing back of sound is called re-echo.

Sometimes re-echo can happen even without mountains or big open fields. It can happen in a closed room too. If you're in a room with hard walls and you clap your hands, the sound can bounce off those walls and come back to your ears. This is another example of re-echo.

So, in simple words, re-echo means the repetition of a sound when it bounces back to us after hitting a hard surface. It's like hearing the sound again, but this time it's not because someone else made the sound, it's because the sound bounced back to us. Like our own personal echo.
