Think of it like this: If you have a perfect sine wave and play it along with its inverse wave-the mirror opposite-the result would be no wave at all. It uses microphones that actively sample the surrounding noise in an environment and then produce an inverse wave that cancels out those sounds. When you put your fingers in your ears when a loud siren goes by, that's a form of passive noise isolation.Īctive noise cancellation is much more complicated. Simply, when an object (such as a thick earpad with memory foam) blocks sound, it is passively (without any battery power) reducing the ambient noise you hear. Passive noise isolation, sometimes called passive noise cancellation, is basically a fancy term for what earplugs do. ![]() Plenty of headphones (and earphones) claim to isolate or reduce noise, but that doesn't mean they offer proper ANC. What's the Difference Between Active Noise Cancellation and Passive Noise Isolation? Read on for our top picks, followed by everything you need to know for your search. We've gathered our favorite noise-cancelling headphones and earphones below.
