How Noise Cancelling Headphones Can Improve Your Listening Experience

Noise cancelling headphones rely on microphones to listen for ambient sounds and produce an anti-noise signal that counteracts unwanted sounds. They are ideal for blocking out train and plane chatter however they will not help you block out your seatmate's animated conversation or screeching breaks.

Active noise cancellation requires good isolation, either by padding around your ears or an earbuds that are sealed or over-ear headphones. We've also examined how the headphones can block lower-frequency noises like traffic or train noise.

What is noise cancellation?

Noise cancellation is a feature that lets listeners focus on their music and audiobooks without being distracted by distracting ambient sounds. Noise cancelling headphones come with microphones that block out external sounds from getting to your ears. This lets you listen to your music or audiobook in complete peace.

Active noise cancellation, also known as ANC is among the most popular headphone features in the market in the present. It is available on many different brands of headphones, in a variety of colors and sizes, and even on some models that are budget-friendly. The technology behind it is surprisingly simple: the earcups or earbuds contain mics that "listen" to ambient noise frequencies, and then play back equal but opposite anti-noise waves to eliminate them before they reach your ears.

This is known as destructive interfering. The valleys and crests of waves cancel each other out, leaving only the music you are listening to. This works great on monotonous, continuous sounds like the drone of an airplane engine, or the hum of your coworker Bob who is unable to shut up. It's less effective when there's high-frequency or sudden noises which are more difficult to detect and block out. For instance the pinging of a computer keyboard or the alarm ringing on your phone.

The foam padding in the ear cup can also be used to cut down on the sound. This is a good option for those who do not need to rely on batteries to provide ANC function, but require a peaceful working environment, or at home.

It's important to remember that all headphones require some kind of power, whether it's for audio processing or battery, for them to function. While ANC can help reduce the impact of external noises, headphones cannot create an enveloping silence around your ears. If the ambient sounds are loud enough, they will get into your ears. This is why it's crucial to wear your headphones comfortably enough to not have any gaps in the fit, so that you can enjoy the maximum benefit from ANC.

How does it work?

The technology behind noise cancelling headphones consists of miniature microphones within the earcups or earbuds which listen to the sounds around you. The sound waves are processed in the headphones to create a sound wave opposite which cancels the sound waves out and stops them from reaching your ears.

Sound waves, whether they're emanating from outside or your music, are made up of air molecules that oscillate. This means that sound waves have a height or amplitude, which is measured by the distance between peaks on an unsteady graph. Sound waves with higher intensities are larger, whereas those with smaller amplitudes are smaller. ANC headphones make use of this by listening to sounds around you and generating an opposing sound that neutralizes them.

ANC headsets have several features to block out noises from the surrounding environment like feedback microphones and ANC chipsets. These chips make use of algorithms to invert sound signals and then emit an opposing signal. This is much like firing anti-ballistic missiles to destroy the warheads that are incoming (again, think of the military-grade countermeasures from war movies).

The ANC drivers in each ear cup generate the opposite signals. When ANC is activated by pressing the button on your headset, the sounds of the environment are reduced or completely eliminated.

The technology behind ANC is impressive, but it comes with some compromises. The additional electronics required to run this technology can add weight and bulk to your headphones. They also use more power, which could cause a decrease in the life of the battery and 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, it's usually due to something else that triggers these feelings, not the ANC headphones themselves.

The good news is that more advanced ANC headsets are beginning to address some of these issues. Bowers & Wilkins PX7 headphones provide different ANC modes, including 'office,' 'plane, and city'. They also have a slider to allow you to customize the amount of external sound that you prefer to hear through. Apple's latest AirPods Pro 2 also feature the same function, and include 'Ambient Aware mode that adjusts the volume of ANC to the surroundings.

What are the best noise cancelling headsets?

Noise cancelling headphones can make a huge differences to your listening experience. They can aid in concentration in the workplace, or block out engine sound on planes and trains. They are also great for commuting or working from home. They can be used with all kinds of audio equipment like computers, tablets and smartphones.

You can try changing the tips of your headphones to see if this improves the fit and lessens the background noise. This is also compatible with earbuds from all brands.

You can adjust the fit of your headphones sale by tilting them back or forward. They're also generally lighter, making them lighter to carry and more convenient to carry around. In our tests, all earbuds provide a certain amount of noise-isolation, but not as effective as over-ear headphones.

What should I look for in noise-cancelling headphones?

The most effective noise cancelling headphones reduce background noise to allow you to concentrate on your music and not be distracted by the surrounding. They usually use active noise cancellation (ANC) to achieve this, although not all ANC headphones are created to be equal. It is crucial to think about the kind of ANC and whether it's in-ear or in-ear and their quality of construction.

In-ear and over-ear headphones are generally the more popular options, and both deliver strong noise isolation. In-ear headphones are more portable and less bulky. While over-ear models are more comfortable but they can also be more expensive. Over-ear headphones are generally more expensive but often offer a better sound quality, while in-ear models provide an affordable option that still delivers solid performance.

Some ANC headphones let you alter the volume of ANC to fit the needs of the moment. You can choose to turn off ANC on an airplane, on public transport, or at home, but switch it back on when you are at work or at home to block out the whirr of your PC's cooling fans or the lawn mower of your neighbour.
