How Noise Cancelling Headphones Can Improve Your Listening Experience

Noise cancelling headphones use microphones to pick up ambient sounds and generate an anti-noise tone that blocks unwanted noises. They're great for blocking out rumbles and chatter from planes and trains but they won't help to stop the sound of your brakes squealing or your passenger's animated conversations.

Active noise cancellation requires a good seal, whether it's earbuds and over-ear headphones, or padding around the ears. We've examined how well they mute lower-frequency constant sounds like train and traffic noise as well.

What is noise cancellation?

Noise cancelling allows listeners to concentrate on their audiobook or music without distraction from the background noise. Noise cancelling headphones are equipped with microphones that block outside sounds from entering your ears. This allows you to listen to your audiobook or music in peace.

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

This is known as destructive interfering. The valleys and crests of waves cancel each other out, leaving only the music that you are listening to. This is great for monotonous, continuous sounds like the drone of an airplane engine or that colleague Bob who can't seem to quit. However, it's less effective on louder or more frequent sounds that are harder to discern and filter out like the click of a keyboard or that alarm beeping from your smartphone.

Another form of noise isolation is passive, which stifles noise by forming an ear-to-ear seal using the foam padding in the ear cups. This can be a good option for those who don't want rely on batteries for their ANC function, Anker A3i Earbuds: Deep Bass - Noise Cancelling - AI-Enhanced – Superior Sound Experience! but prefer a peaceful environment while working or relaxing at home.

It's important to remember that all headphones require some form of power, be it for battery or audio processing, to function. While ANC can reduce most external noises, they are unable to create the illusion of a cone-shaped silence around your ears. If the ambient sounds are loud enough, they will simply bead into your ears. This is why it's crucial to wear the headphones snugly enough that they don't have any gaps in the fit so you can get the full benefit of ANC.

How do you make it work?

The technology behind noise cancelling headsets involves tiny microphones in the earcups, or buds, which listen to sounds around you. They're then processed inside the headphones to create an opposite sound wave that effectively cancels out those sounds and prevents the sound from reaching your ears.

Sound waves, regardless of whether they're emanating from outside or from your music, are composed of air molecules that oscillate. This means that sound has a height, or the amplitude. It is measured by the distances between peaks in an unsteady graph. Sound waves with greater amplitudes are taller, while those with smaller amplitudes are smaller. ANC headphones use this to create an audio that is in opposition to the sounds you hear around you.

ANC headsets are equipped with several features to block out noises from the surrounding environment, including feedback mics and ANC chipsets. These chips employ algorithms to reverse incoming sound signals and then emit an opposite signal, which is similar to launching anti-ballistic missiles to destroy the warheads coming in (again think of military-grade countermeasures from war movies).

The ANC drivers in each ear cup create these opposing signals. When you activate ANC by pressing a button on your headset, the sounds of the surrounding environment are minimized or eliminated.

The technology behind ANC is amazing, it comes with a few drawbacks. The additional electronics required to run this technology can increase the weight and size of your headphones, making them bulkier than comparable models. They also consume more power, which can cause a decrease in the life of the battery and some high-frequency hiss.

Another issue is that some users have reported being disoriented or dizzy while wearing ANC headphones. While this is a problem, it's usually due to something else triggering those feelings, not the ANC headphones itself.

The good news is that more advanced ANC headsets are beginning to address a few of these issues. The Bowers & Wilkins PX7, for example, offers different ANC modes such as 'office', 'plane' and 'city' with a slider that lets you customize the amount of external sounds you want to pass through. Apple's newest AirPods Pro 2 also feature the same function, and include the 'Ambient Aware mode' that adjusts the volume of ANC to the surroundings.

They may be more comfortable if you tilt them forwards or backwards to adjust their fit. They are also lighter, which makes them more mobile and easy to carry. In our tests, the majority of earbuds offer some level of noise isolation but it's not as effective as over-ear headphones.

What should I look out for when buying headphones that block out noise?

The best noise cancelling headphones minimize ambient sound so you can focus on audio without having to worry about your surroundings. They typically use active noise cancellation (ANC) to achieve this, however not all ANC headphones are created equal. It's important that you consider the type of ANC, whether it's over-ear or in ear and also their build quality.

Both in-ear and over-ear headphones provide superior noise isolation. In-ear headphones are more portable and less bulky. While over-ear models can be more comfortable but they can also be more expensive. Over-ear headphones are more expensive however, they usually have better sound. In-ear models are more affordable, but still deliver a solid performance.
