Example:
Imagine you're trying to make a phone call in a noisy cafe, but your voice gets lost among all the chatter and clinking dishes. This situation is similar to how an echo works because just as your voice struggles to cut through the ambient noise and reach the person on the other end, a sound wave travels until it hits a surface and reflects back to the listener. In both scenarios, whether it's your voice in a bustling cafe or a sound wave bouncing back from a wall, the challenge lies in overcoming interference to ensure the original message or sound is heard clearly.

Echo: A reflected sound wave. Echo. An echo is when a sound bounces off a surface and returns to your ears.
