How do noise cancelling headphones work?

With the rapid development of science and technology, and in order to meet the needs of various consumers, the term noise-cancelling headphones has gradually entered the public’s field of vision. A series of terms such as active noise cancellation and passive noise cancellation have attracted people’s attenetion.

Noise-cancelling headphones have changed the game when it comes to headphones. As well as playing your favourite music ,game, podcast or video, they can diminish or erase the sounds around you to some extent.

They have become increasingly popular due to their incredible features, especially as so many Australian workers have switched to noisy at-home offices.

What are noise-cancelling headphones?

Noise-cancelling headphones have a built-in capability of minimising or completely negating the noises around you. Instead of just muffling the sounds to dull them, as you would find with a set of earmuffs, noise-canceling headphones actively work to reduce external noises.

Importantly, noise-cancelling headphones also work as regular headphones.They don’t just cancel external noises-they also play music and podcasts, and can function as a headset for work with an in-built microphone in some models. That’s why they’ve become such a popular option. They work both ways to ensure you can listen to the audio of your choice without having to turn it up to full volume to hear it over the sounds in the backgroud.

The current noise-cancelling headphones usually only have a good effect on low-frequency noise, but for high-frequency sound sources such as human voices, there is no headphones on the market that can efficiently deal with them.

Therefore, if you want to reduce some low-frequency ambient sounds indoors and when taking vehicles, buying a noise-cancelling headset is a good choice.
