What Are NoiseCanceling Headphones & How They Work Explained

Noise-canceling headphones have become a staple for those who prefer the best possible listening experience. Whether that experience be during a tiresome workout or even an intense gaming session, noise-canceling offers advantages for everyone. Simply hearing the word noise-canceling doesn’t fully explain why the feature is so useful, although it begins to make more sense once it’s understood how the magic of noise-canceling works.

In reality, noise-canceling might be one of the most important and welcomed innovations in audiophile technology, and it is important to understand there is more than one technique used to achieve noise-canceling. These differences are often referred to as passive and active. Passive noise-canceling headphones are often less desirable, because there is no real technology that goes into it. Instead, passive noise-canceling is achieved by the shape of the headphones or the material used to help keep excess noise from entering the listener’s ear.

Active noise-canceling is much more impressive, and that is why many of the highest-rated headphones on the market, including Bose headphones, label themselves as active noise-canceling. It has become such a popular feature that high-end earbuds have begun taking advantage of it as well. There are no drawbacks to active noise-cancellation which further adds to the feature’s appeal, even if someone may never use it.

Active Noise Reduction For Passive Listening

When listening to a song, a podcast, or even talking on the phone, it can be frustrating to hear the low hum of the dishwasher, a car passing by, or even that ceiling fan that clicks just a little too much. Noise-canceling headphones exist for exactly this reason. The goal is to deliver clear high-quality audio to the ears without all that noise pollution. Headphones are able to reduce unwanted background noise by countering it with low-frequency anti-noise. By using microphones located inside and outside the earpiece, the headphones can pick up sounds that would be distracting to the listener and combat them with the low-frequency tones. Of course, background noise doesn’t always rest at a set volume and can become louder and fainter in a matter of seconds. This is why many noise-canceling devices will often adjust the pitch of the low-frequency sounds hundreds of times per second. This ensures that you are always getting the most out of your audio experience.

For people who use their headphones a lot for phone calls and multiplayer gaming, active-noise cancellation can also be a very helpful tool. Much like when listening to music, active noise-canceling filters out the sound around the user in order to isolate the voice. This makes for better call quality that helps eliminate the distractions that would make the call harder to hear for both parties. This cuts down on the amount of time asking someone to repeat something, due to that distracting background noise.

What makes active noise-canceling so great as well is that it can be turned on and off at the user’s discretion. So, for those times when it is important to not be too engrossed in the listening experience that is always an option. Overall, it is an incredible feature to have and one that should not be overlooked when purchasing that next set of headphones.
