How Noise Cancelling Headphones Can Improve Your Listening Experience

Noise cancelling headphones employ microphones to listen for ambient sounds and generate an anti-noise sound that counteracts unwanted noises. They're great to block 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 good isolation, either through padding your ears or a solid seal with earbuds or over-ear headphones. We've tested how well they muffle lower-frequency constant sounds, like traffic and train noise also.

What is noise cancellation?

Noise cancelling lets listeners concentrate on their audiobook or music without distraction from 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 complete peace.

Active noise cancellation (ANC) is among the most commonly used headphone features on the market. It is available on many different brands of headphones, with a variety of sizes and Headphones cheap colors, and even on some budget models. The concept is quite simple: the earbuds or earcups have mini-microphones that "listen" to ambient sound frequencies and playback equal but opposite anti noise waves to cancel them before they reach your ear.

The crests and troughs of these waves cancel each other in a process known as destructive interference, leaving you with nothing other than the music you're listened to. This is particularly effective for monotonous, continuous sounds like the drone of an airplane engine or the hum of your colleague Bob who is unable to shut up. However it's not as effective on high-frequency or sudden sounds that are harder to discern and filter out, such as the sound of a keyboard, or the alarm sounding from your smartphone.

The foam padding inside the ear cup can be used to reduce the noise. This is a great alternative for those who don't want to rely on batteries to provide their ANC function, but need to have a peaceful environment when working or at home.

All headphones require power to function, regardless of whether it's an audio processor or battery. While ANC can cut down on most external noises, it isn't able to create an enveloping silence around your ears. If the sounds around you are loud enough, they will bleed into your ears. It is essential to wear your headphones tightly enough to ensure there aren't any gaps in the fit. This will allow you to enjoy the full benefit of ANC.

How do you make it work?

The technology behind noise cancelling headphones is based on miniature microphones inside the earcups or earbuds that listen to the sounds around you. They're processed inside the headphones to produce an opposing sound wave that effectively blocks out the sounds and prevents them from reaching your ears.

Sound waves, whether coming from the outside or from your music, are composed of oscillating air molecules. This means that sound waves have a size or amplitude. This is measured by the distance between peaks of an undulating graph. Sound waves with higher amplifies are larger, while those with shorter magnitudes are smaller. ANC headphones use 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 like feedback microphones 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 incoming warheads.

These opponing signals are produced by two ANC drivers within each ear cup. When the ANC is activated by pressing the button on your headset, the sounds of the surrounding noises are reduced or removed.

The technology behind ANC is impressive, it comes with some tradeoffs. The additional electronics required to enable this technology can add weight and size to your headphones, making them bulkier than similar-looking alternatives. They also consume more power, which could cause a reduction in battery life, and even high-frequency hiss.

Another issue is that some users have reported being disoriented or dizzy while wearing ANC headphones. Although this can be a source of frustration, it's usually due to something else triggering those feelings, not the ANC headphones themselves.

The good news is, more advanced ANC headsets are beginning to address a few of these problems. Bowers & Wilkins PX7 headphones provide different ANC modes, such as 'office,' 'plane, and city'. They also have an adjustment slider that allows you to customize the amount of external sound you want through. Apple's newest AirPods Pro 2 also feature the same function, and include 'Ambient Aware mode which digitally adjusts the amount of ANC to match your surroundings.
