How Noise Cancelling Headphones Can Improve Your Listening Experience

Noise cancelling headphones rely on microphones to track ambient sound and generate an anti-noise sound that counteracts unwanted noises. They are ideal for blocking out rumbles and chatter from trains and planes, though they don't do much to cut the sound of your brakes squealing or your passenger's animated conversations.

Active noise cancellation requires a great seal, whether it's earbuds and over-ear headphones or padding for the ears. We've also tested whether the Headphones Noise Cancelling can block lower-frequency sounds such as traffic and train noise.

What is noise cancelling?

Noise cancellation is a feature which allows listeners to concentrate on their music and audiobook without being distracted by distracting background sounds. Noise cancelling headphones have built-in 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 commonly used headphone features on the market. It's available from a variety of brands of headphones, in various sizes and colors, and is even included in some budget models. The technology behind them is simple: the earcups or earbuds contain miniature microphones that "listen" to ambient noise frequencies, and headphones Noise cancelling then play back equal but opposite noise waves to cancel them out before they reach your ears.

This is referred to as destructive interfering. The valleys and crests of the waves cancel each other out, leaving only the music you're listening to. This is great for monotonous, continuous sounds such as the drone of an airplane engine or the hum of your colleague Bob who just can't seem to quit. However it's less effective for high-frequency or sudden sounds that are more difficult to discern and filter out like the sound of a keyboard, or the alarm sounding from your phone.

Another type of noise isolation is passive, which blocks sound by creating a seal with your ears with the padding of the ear cups. This is a good option for those who do not want to rely solely on batteries to provide ANC functionality, but still require a peaceful working environment or at home.

All headphones require power to function, regardless of whether it's a battery or audio processing. Even though ANC can cut out the majority of external noise, the headphones can't create a quiet cone around your ears. If the ambient sounds are too loud they'll simply bleed through to 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, to get the maximum benefit from ANC.

How do you make it work?

The technology behind noise cancelling headsets consists of tiny microphones within the earcups, headphones Noise cancelling or buds, which listen to sounds around you. They are then processed inside the headphones to create an opposite sound wave which effectively blocks out the sound and prevents them from reaching your ears.

Sound waves, whether coming from the outside or through your music are made up of air molecules that oscillate. This means that the sound waves have a height or amplified. It is measured by the distances between peaks on an undulating graph. Sound waves with higher intensities are larger, whereas those with smaller amplifies are smaller. ANC headphones make use of this to create a sound that is opposite to the sounds you hear around you.

ANC headsets come with several features to block out ambient noises, including feedback mics and ANC chipsets. These chips use algorithms that invert incoming sound and then release a counter-signal which is similar to firing antiballistic missiles at warheads that are coming in.

The ANC drivers inside each ear cup produce these opposite signals. When you activate the ANC by pressing a button in your headset, the sounds of the outside are muffled or eliminated.

The technology behind ANC is impressive, it comes with some tradeoffs. The additional electronics needed to make this technology work can make your headphones heavier and larger. your headphones, making them heavier than similar-looking alternatives. They also draw more power, which can lead to a shorter battery life and potentially some high-frequency hiss.

Another issue is that some users have reported feeling dizzy or disoriented wearing ANC headphones. Although this can be a source of frustration but it's usually due to something else that triggers these sensations, rather than the ANC headphones itself.

The good news is, more advanced ANC headsets are beginning to address these problems. The Bowers & Wilkins PX7, for instance, has various ANC modes such as "office", 'plane' and 'city', along with an adjustment slider that lets you customize the volume of external sound you want to let through. Apple's newest AirPods Pro 2 also feature the same feature, and comes with 'Ambient Aware mode which digitally adjusts the amount of ANC to match your surroundings.
