How Noise Cancelling Headphones Can Improve Your Listening Experience

Noise cancelling headphones rely on microphones to monitor ambient sound and create an anti-noise signal that counteracts unwanted noises. They are ideal to block out rumbles and chatter from trains and planes but they won't make much difference to the sound of the squealing brakes or your friend's animated conversations.

Active noise cancellation requires a strong seal whether it's earbuds, over-ear headphones or padding for the ears. 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 which allows listeners to concentrate on their music and audiobook without being distracted by ambient sounds. Noise cancelling headphones are equipped with microphones that block out external sounds from reaching your ears. This lets you enjoy your audiobook or music in complete peace.

Active noise cancellation (ANC) is one of the most popular headphone features that are available. It is available from a variety of different brands of headphones, in a variety of sizes and colors, and even on some budget models. The technology behind it is surprisingly simple: the earcups or earbuds have miniature microphones that "listen" to ambient sound frequencies, then play back equal but opposing anti-noise waves to block them out before they reach your ears.

The crests and troughs of these waves cancel out each other, a process referred to as destructive interference, leaving you with nothing other than the music you're listened to. This works well with monotonous, constant sounds like the hum of an aircraft engine or Bob's constant chatter. It's less effective with high-frequency or sudden noises which are more difficult to detect and block out. For example the pinging sound of a computer keyboard or the alarm sounding on your phone.

Another form of noise isolation is passive, which blocks noise by forming a seal with your ears using the foam padding in the ear cups. This can be a good option for those who don't want to rely on batteries for their ANC function, but want to enjoy a quiet environment when working or at home.

It's important to remember that all headphones require some form of power, whether it's for audio processing or battery, for them to function. Although ANC can help reduce the impact of external noises, they are unable to create an enveloping silence around your ears. If the sounds around you are loud enough, they'll get into your ears. This is why it's important to wear the headphones snugly enough that they don't have any gaps in the fit to get the full benefit of ANC.

What exactly is it that makes it work?

The technology behind noise cancelling headphones consists of miniature microphones within the earcups or earbuds which listen to the sounds around you. They are then processed inside the headphones to produce an opposite sound wave which effectively cancels out those sounds and prevents them from reaching your ears.

Sound waves, whether coming from the outside or through your music are composed of air molecules that oscillate. This means that sound waves have a size or amplitude. This is measured by the distance between peaks on an undulating graph. Taller sound waves have higher amplitudes and shorter ones have smaller amplifies. ANC headphones on sale take advantage of this by focusing on the sounds around you and generating an opposing sound that neutralizes them.

ANC headsets come with a variety of features that help in blocking ambient noises, including feedback microphones and an ANC chipset. These chips employ algorithms to invert incoming sound signals and then emit an opposing signal. This is similar to launching anti-ballistic missiles to shoot down the warheads that are incoming (again, think of the military-grade countermeasures from war movies).

The ANC drivers inside each ear cup create these opposing signals. When ANC is activated by pressing a button on your headset, the sounds of the environment are reduced or completely eliminated.

The technology behind ANC is amazing, it comes with a few trade-offs. The additional electronics required to run this technology can add weight and bulk to your headphones. They also use more power, which can lead to a shorter battery life, and even high-frequency hiss.

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

The good news is, more advanced ANC headsets are beginning to address a few of these issues. Bowers & Wilkins PX7 headphones provide various ANC modes, including 'office,' 'plane, and city'. They also have a slider to allow you to customize the amount of external sound that you would like to hear through. Apple's newest AirPods Pro 2 also feature a similar function, with 'Ambient Aware' mode that digitally adapts the level of ANC to your surroundings.
