How Noise Cancelling Headphones Can Improve Your Listening Experience

Noise cancelling headphones utilize microphones to listen for ambient sounds and generate an anti-noise tone that blocks unwanted noises. They are excellent for blocking out plane and train chatter however they will not assist in blocking out your seatmate's animated conversation or squealing breaks.

Active noise cancellation requires good over the ear headphones isolation, either by padding your ears with an effective seal using earbuds or over-ear headphones. We've tested their ability to can block lower-frequency sounds like train and traffic noise, too.

What is noise cancelling?

Noise cancelling helps listeners focus on their music or audiobook without distraction from distracting ambient sound. Noise cancelling headphones are equipped with microphones that block external sounds from reaching your ears. This allows you to enjoy your audiobook or music in peace.

Active noise cancellation, or ANC is among the most sought-after headphone features in the market today. It is available from a variety of different brands of headphones with a variety of sizes and colors and even on some budget models. The technology is simple: the earcups or earbuds have miniature microphones which "listen" to ambient sound frequencies and playback equal but opposite anti noise waves to block the sound before it reaches your ear.

The crests and troughs of these waves cancel each other in a process known as destructive interference, leaving nothing other than the music you're listening to. This works well with continuous, monotonous sounds such as the drone of an aircraft engine or Bob's endless chatter. However it's less effective for sudden or higher-frequency sounds that are harder to discern and filter out, such as the click of a keyboard or the alarm sounding from your smartphone.

Another form of noise isolation is passive, which reduces noise by forming an ear-to-ear connection with the padding of the ear cups. This is a good choice for those who do not want to rely only on batteries for ANC functions, but need a quiet work environment or at home.

All headphones require power to function, regardless of whether it's an audio processor or battery. Although ANC can cut out the majority of external noise, it's important to remember that the headphones won't be able to create a cone of silence around your ears. If the ambient sounds are too loud they'll be able to bleed through your ears. This is why it's important to wear the headphones in a snug way enough to not have any gaps in the fit, so that you can enjoy the full benefit of ANC.

What exactly is it that makes it work?

The technology behind noise cancellation headphones involves miniature microphones in the earcups, or earbuds, that listen to the sounds around you. They're processed inside the headphones to create an opposite sound wave which effectively blocks out the sounds and blocks them from reaching your ears.

Sound waves, whether they're emanating from outside or from your music, are made up of oscillating air molecules. This means that sound has a height, or amplitude. It is measured by the distances between peaks in an unsteady graph. Sound waves with higher amplitudes are taller, while those with lower magnitudes are smaller. ANC headphones make use of this to create the opposite sound to the sounds you hear around you.

ANC headsets feature a variety of features that make them more effective at blocking ambient sounds, including feedback microphones and an ANC chipset. These chips employ algorithms to reverse incoming sound signals and then release an opposite signal, which is basically like launching anti-ballistic missiles that shoot down the warheads coming in (again, think of the military-grade countermeasures seen in war movies).

The ANC drivers in each ear cup generate these opposing signals. When ANC is activated by pressing a button on your headset, the sounds of the surrounding noises are lowered or removed.

The technology behind ANC is amazing, it comes with a few trade-offs. The additional electronics needed to make this technology work can make your headphones heavier and larger. your headphones, making them bulkier than similar-looking alternatives. They also consume more power, which can result in a shorter lifespan of the battery, as well as high-frequency hiss.

Another issue is that some users have reported feeling dizzy or disoriented while wearing ANC headphones. This can be a bit frustrating, but is usually caused by something else, not by ANC.

The good news is that the latest ANC headphones are starting to address a few of these issues. The Bowers & Wilkins PX7, for example, offers several ANC modes, including 'office', 'plane' and 'city', with a slider that lets you customise the amount of external noise you want to pass through. Apple's AirPods Pro 2 feature a similar feature, which includes an 'Ambient Aware mode which adjusts the volume of ANC according to your surroundings.
