Imagine you're trying to listen to your favorite song on your phone, but someone next to you is shouting really loudly, that's interference from external sources!
Like a noisy neighbor
When you’re listening to music, it’s like having a quiet conversation. But if a loud person starts talking right beside you, it makes it harder to hear the music clearly. That loud person is like an external source, something outside of your phone that's adding noise.
What happens in real life?
In the world of sound or signals (like on your phone), interference means other things are mixing in and making it harder for you to understand what you're trying to hear. It’s like when you’re trying to read a book, but someone keeps tapping you on the shoulder, it messes up your focus.
So, interference from external sources is just something extra that gets in the way of what you're trying to listen to or see clearly.
Examples
- You can't hear your friend on the phone because a loud car passes by.
- Your TV starts showing static because of a thunderstorm outside.
