Those vibrations don't stay the same strength forever. As they travel farther from where they started, they spread out over a bigger space, and each part carries less energy. That's why sound fades the farther away you are from it. *(drawing: The same shout, measured at 1, 5, and 10 metres away. The farther the sound travels, the shorter the bar, and the fainter it sounds.)* **Example.** Mia claps her hands once. Her friend standing right beside her hears a loud, sharp clap. Another friend standing far across the playground hears the very same clap, but it sounds soft and faint. The clap didn't change. It's the same vibrations, just weaker by the time they reach the far-away friend's ears. **Tip.** Next time you're outside, ask a friend to walk away from you while talking normally. Notice how their voice fades the farther they go. That's not your hearing failing, it's the sound vibrations spreading out and losing strength. **Recap.** Sound doesn't disappear with distance, it just spreads out, loses strength, and gets fainter the farther away you are from it. ## Practice 8 questions on this page, each with its working shown. ## Needs first - [Sound travels through materials](https://lightmysky.com/learn/science/sound-travels-through-materials-mt_ydtcIBwHB9) ## Opens up - [How Sound Waves Travel](https://lightmysky.com/learn/science/how-sound-waves-travel-mt_DQk9oDE7gr)
