How To Explain Headphones Noise Cancelling To Your Grandparents

How Noise Cancelling Headphones Can Improve Your Listening Experience

Noise cancelling headphones utilize microphones to pick up ambient sounds and produce an anti-noise tone that blocks unwanted sounds. They are great to block out train and plane conversations however they will not help you block out your seatmate's animated conversation or snarling breaks.

Active noise cancellation requires good isolation, either by padding your ears or an effective seal using earbuds or over-ear headphones. We've also tested how well the headphones muffle lower-frequency sounds like traffic and train noise.

What is noise cancelling?

Noise cancellation is a feature that helps listeners concentrate on their music and audiobook without being distracted by distracting ambient sounds. Noise cancelling headphones are fitted with microphones that block outside sounds from getting to your ears. This lets you listen to your audiobook or headphone Sales music in complete peace.

Active noise cancellation (ANC) is among the most popular headphone sales features on the market. It is available on many different brands of headphones in a wide range of sizes and colors, and even on some models that are budget-friendly. The technology is simple: the earbuds or earcups have mini-microphones that "listen" to ambient sound frequencies and then play back equal but opposing noise waves to cancel them before they reach your ear.

This is known as destructive interfering. The valleys and crests of waves cancel each and leave only the music that you are listening to. This is great for monotonous, continuous sounds like the drone of an airplane engine or your coworker Bob who is unable to stop talking. It's less effective for high-frequency or sudden noises which are more difficult to detect and eliminate. For example the pinging of a keyboard on your computer or the alarm ringing on your smartphone.

Another kind of noise-isolation is passive, which stifles the sound by forming a seal with your ears with the padding of the ear cups. This can be a good alternative for those who don't want rely on batteries to provide ANC capability, but still need to have a peaceful environment while working or relaxing at home.

It's important to note that all headphones require some form of power, whether for battery or audio processing in order to work. Although ANC can help reduce the impact of external noises, it isn't able to create an enveloping silence around your ears. If the ambient sounds are loud enough, they'll bleed into your ears. This is why it's important to wear the headphones snugly enough to not have any gaps in the fit to get the maximum benefit from ANC.

How does it work?

The technology behind noise cancellation headsets consists of tiny microphones within the earcups or earbuds which listen to sounds around you. The sounds are then processed by the headphones to create a sound wave that cancels them out and blocks them from reaching your ears.

Sound waves, regardless of whether they're emanating from outside or your music, are composed of oscillating air molecules. This means that sound waves have a height or amplitude, which is measured by the distance between the peaks on an undulating graph. Higher-quality sound waves have higher amplitudes and shorter ones have smaller intensities. ANC headphones benefit from this by focusing on the sounds around you and generating an opposite sound that neutralizes them.

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

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

The technology behind ANC is impressive but it comes with some compromises. The additional electronics required to enable this technology can increase the weight and size of your headphones, making them heavier than similar-looking alternatives. They also require more power, which can lead to a shorter life of the battery and some 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 triggering those sensations, rather than the ANC headphones itself.

The good news is that more sophisticated ANC headphones are beginning to address a few of these issues. The Bowers & Wilkins PX7, for instance, comes with different ANC modes like "office", 'plane' and 'city', along with an adjustment slider that lets you adjust the volume of external sound you want to let through. Apple's new AirPods Pro 2 also feature the same feature, and comes with 'Ambient Aware mode' which digitally adjusts the amount of ANC to your surroundings.
