What is SNR?

SNR is how loud your favorite song is compared to the background noise when you're listening on your headphones.

Imagine you're at a party, and you really want to hear your friend whispering in your ear, but there's music playing, people talking, and maybe even a blender going. The louder your friend's voice is compared to all that other sound, the easier it is for you to understand them. That’s like SNR, it measures how clear the main signal (like your friend’s whisper) is compared to the background noise (the party sounds).

Think of SNR as a scale from 1 to 100. If the music at the party is really loud, and your friend is barely speaking, it might be like an SNR of 1, hard to hear! But if you turn off the music and your friend speaks clearly, that’s like an SNR of 100, super easy to understand!

In real life, SNR helps things like radios, phones, and even your headphones work better. The higher the SNR, the clearer everything sounds, just like how you can hear your friend better at a quiet party!
