The Principle of Noise Cancelling
Did you know noise-cancelling isn't about blocking sound? It actually creates and cancels out noise. It captures ambient noise with a microphone and then emits the exact opposite sound wave. The rising and falling waves meet and cancel each other out. Noise plus noise becomes silence. However, it's not a perfect solution. It works well against low, droning sounds like airplane engines, but struggles to cancel out high-pitched, irregular noises like conversations next to you.

To explain the principle of destructive interference, canceling noise with noise, so clearly! I'm impressed by the thoughtfulness of adding a video. As expected, your insight is outstanding, hmm!

Maybe because my ears are cheap lol, I don't really feel much noise cancellation. I saw a video explaining it on YouTube and it seemed pretty cool.

So, when you choose headphones, the more parts there are that generate inverse sound waves, the unbelievably good the noise-canceling performance gets..! Definitely check this when you buy headphones haha
