This is what most of us tend to think of when we hear the words “ noise-cancelling headphones.” It’s what helps the wearer drown out ambient noise and focus on talking to someone or listening to music.

So if you don’t want to be the friend who always sounds like they’re in a wind tunnel or on the set of an action movie, a headset with noise-cancelling microphones might be for you. In the end, the basic principle is the same: Your voice gets the green light, while the background noise is stopped at the door. Jabra call theirs Noise Blackout™, for example. This may sound like voodoo, but it works.Ĭompanies use different branding for their dual-mic noise cancellation. Combined with some digital algorithms, they “subtract” the surrounding noise from the equation, leaving just your voice. While the first one picks up your voice, the other one picks up more of the surrounding noise. How? In a nutshell, the two mics have some distance between them, which means one of them is closer to your mouth than the other. More advanced headsets use multiple mics to truly take noise cancellation up a notch. Some headsets even come with a special wind sock that practically eliminates all wind noise. This noise cancellation can be achieved in different ways, including microphone shape and positioning, digital signal processing, and other tech words. We’ve already covered noise-cancelling microphones in an earlier post. Noise-cancelling microphones are built to pick up your voice while ignoring the background noise. Instead, it helps others hear you better. This doesn’t actually benefit you directly. Now let’s look at each one of them in a bit more detail. The second type protects you – the wearer – so that you aren’t disturbed by that same bar noise. The first type helps the person on the other end of the line to hear your voice instead of the ruckus in the bar you’re calling from. Let’s try to unravel the riddle.įirst off, there are two broad types of noise cancellation – one in the microphone(s) and one in the headphones themselves. It’s not your fault: Depending on the context, noise cancellation can mean a number of things, and companies aren’t exactly consistent in how they use the term. I can also bet that you weren’t always quite sure what it meant. If you’ve ever shopped for headsets or headphones, I bet you’ve heard the term “noise cancellation” used once or twice.
