How Noise Cancelling Headphones Can Improve Your Listening Experience

Noise cancelling headphones use microphones to listen for ambient sounds and produce an anti-noise signal that blocks out unwanted sounds. They are ideal for blocking out rumbles and chatter from trains and planes however they can't make much difference to the sound of screeching brakes or your seatmate's animated conversations.

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

What is noise cancellation?

Noise cancellation is a feature which allows listeners to concentrate on their music and audiobooks without being distracted by ambient sounds. Noise cancelling headphones have built-in microphones that actively block external sounds before they get to your ears, effectively reducing the outside world so that you can listen to your music or audiobook in peace.

Active noise cancellation (ANC) is among the most popular headphone features on the market. It's offered by a variety of brands of headphones, in a variety of sizes and colors, and it's even found on a few budget models. The concept is simple: the headphones or earcups contain tiny microphones that "listen" to ambient sound frequencies and playback equal but opposite anti noise waves to cancel them before they reach your ear.

This is known as destructive interfering. The valleys and crests of the waves cancel each and leave only the music you're listening to. This is particularly effective for monotonous, constant sounds, such as the drone of an aircraft engine or Bob's constant chatter. However it's not as effective on high-frequency or sudden sounds that are harder to discern and filter out, such as the click of a keyboard or that alarm beeping from your smartphone.

Another form of noise isolation is passive, which stifles sound by creating a seal with your ears by using the padding of the ear cups. This is a great option for those who do not need to rely on batteries to provide ANC functions, but want a quiet working environment, or at home.

It's worth noting that all headphones require some kind of power, whether it's for battery or audio processing in order to work. 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'll bead into your ears. This is why it's important to wear your headphones comfortably enough to not have any gaps in the fit so you can get the full benefit of ANC.

How does it work?

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

Sound waves, whether they're coming from the outside or from your music, are made up of air molecules that oscillate. This means that sound has a height or amplified. It is measured by the distances between peaks on an oscillating graph. Higher-quality sound waves have higher amplifies, while shorter ones have smaller intensities. ANC headphones make use 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 can make them more effective in blocking ambient sounds such as feedback microphones and an ANC chipset. These chips use algorithms that reverse the sound coming in and then release a counter-signal, which is like firing antiballistic missiles at warheads that are coming in.

The ANC drivers inside each ear cup produce the opposite signals. When you activate ANC by pressing a button within your headset, the sounds of the outside are muffled or eliminated.

The technology behind ANC is impressive but it comes with some tradeoffs. The extra electronics needed to enable this technology can add weight and bulk to your headphones. They also use more power, which could result in a decrease in battery life, and even high-frequency hiss.

Another issue is that many users have reported experiencing disorientation or dizziness when wearing ANC headphones. Although this can be a source of frustration, it's usually due to something else that is triggering these sensations, not the ANC itself.

The good news is that the latest ANC headphones are starting to address some of these issues. Bowers & Wilkins PX7 headphones are a good example, offering various ANC modes, such as 'office,' 'plane, and city'. They also have an adjustment slider that allows you to alter the amount of external sound you would like to hear through. Apple's AirPods Pro 2 feature a similar feature, and a 'Ambient Aware mode which alters the amount of ANC depending on the environment.

Over-ear headphones are usually more comfortable than in-ear designs. They have a larger headband and cushioned cups that sit over your ears, helping to keep them in place for longer. They're also more effective at blocking out ambient noise. There are exceptions, however, and the best headphones for noise cancellation will be determined by your lifestyle and music preferences.

Most over-ear headphones will provide some degree of noise reduction However, the degree of noise reduction will vary greatly depending on the design and how well they fit in your ears. An insufficient fit could let in more ambient noise, and it can even affect the quality of the bass.

In-ear headphones on sale can be uncomfortable to wear for long listening sessions as they do not sit on your ears, instead, but inside them. You can adjust the size of your headphones by tilting them either forward or backward. They're also typically lighter, which makes them lighter to carry and more portable. In our tests, we found that most earbuds provide some noise cancellation. However, they're not nearly as good as a pair of over-ear earphones.

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

The best noise cancelling headsets reduce background noise to allow you to concentrate on your music and not be distracted by your surroundings. They typically use active noise cancellation (ANC) to achieve this, however not all ANC headphones are made equal. It is important to take into consideration the type of ANC employed, whether they're over-ear or in-ear, and their build quality.

In-ear and over-ear headphones are generally the more well-known options, and both deliver strong noise isolation. In-ear headphones are more compact and less bulky. While models with over-ears can be more comfortable, they can also be more expensive. Over-ear headphones are more expensive but they typically have better sound. In-ear models are less expensive and still provide a good performance.
