How Noise Cancelling Headphones Can Improve Your Listening Experience

Noise cancelling headphones Samsung rely on microphones to track ambient sound and produce an anti-noise signal that blocks unwanted sounds.

What is noise cancelling?

Noise cancellation is a feature that helps listeners concentrate on their music or audiobook without being distracted by distracting ambient sounds. Noise cancelling headphones are equipped with microphones that block out external sounds before they get to your ears, effectively reducing the outside world so that you can listen to your music or audiobook with peace.

Active noise cancellation (ANC) is one of the most common headphone features on the market. It is available on many different brands of headphones, with a variety of sizes and colors and even on some budget models. The technology behind them is simple: the earcups or earbuds contain tiny microphones that "listen" to ambient sound frequencies, and then play back equal but opposite anti-noise waves to cancel them out before they reach your ears.

The crests and troughs of these waves cancel each one another in a process referred to as destructive interference, leaving you with nothing other than the music you're listening to. This works great on monotonous, continuous sounds like the drone of an airplane engine or that colleague Bob who is unable to stop talking. However it's not as effective on louder or more frequent sounds that are more difficult to recognize and filter out, such as the sound of a keyboard, or that alarm beeping from your smartphone.

Sound waves, regardless of whether they're emanating from outside or your music, are made up of oscillating air molecules. This means that sound has a height, or the amplitude.

ANC headphones benefit from this by listening to the sounds around you and creating an opposing sound that neutralizes them.

ANC headsets have numerous features that block out ambient noises like feedback microphones and ANC chipsets. These chips make use of algorithms to invert incoming sound signals and then emit an opposing signal, which is similar to launching anti-ballistic missiles that shoot down the warheads that are incoming (again think of the military-grade countermeasures in war films).

These signals that are opposite to each other are generated by a pair of ANC drivers in each earcup. When ANC is activated by pressing the button on your headset, the sound of the environment are lowered or completely eliminated.

While the technology behind ANC is impressive, it does come with a few drawbacks. The additional electronics required to make this technology function can add weight and bulk to your headphones. They also draw more power, which can cause a reduction in battery life and possibly high-frequency hiss.

The Bowers & Wilkins PX7, for instance, comes with different ANC modes like 'office', 'plane' and 'city' with a slider that lets you customise the amount of external noise you want to let through.
