How Noise Cancelling Headphones Can Improve Your Listening Experience

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

Active noise cancellation requires a strong seal whether it's earbuds or over-ear headphones or padding around the ears. We've also tested whether the headphones can block lower-frequency noises like traffic or train noise.

What is noise cancellation?

Noise cancelling is a feature that lets listeners concentrate on their audiobook or music without distraction from background noise. Noise cancelling headphones are equipped with microphones that actively block external sounds before they reach your ears, effectively shutting out the outside world so you can listen to your music or audiobook in peace.

Active noise cancellation, also known as ANC, is one of the most sought-after headphone features in the market today. It is available from many different brands of headphones, in a variety of sizes and colors and even on some budget models. The technology behind it is simple: ear cups or earbuds are equipped with tiny microphones that "listen" to ambient sound frequencies, then play back equal but opposing noise waves to block them out before they reach your ears.

This is known as destructive interfering. The valleys and crests of the waves cancel each one another out, leaving the music you're listening to. This works great on monotonous, continuous sounds like the drone of an airplane engine, or your colleague Bob who is unable to quit.

All headphones require power to function, regardless of whether it's an audio processor or battery. Although ANC can block out most external noise, the headphones can't create a quiet cone around your ears. If the ambient sounds are too loud, they'll simply bleed through to your ears. This is why it's crucial to wear your headphones comfortably enough that they don't have any gaps in the fit, so you can get the full benefit of ANC.

How do you make it work?

The technology behind noise cancellation headphones is based on miniature microphones inside the earcups or earbuds that listen to the sounds around you.

Sound waves, whether coming from the outside or from your music, are made up of air molecules that oscillate. This means that sound has a height, or the amplitude. It is measured by the distances between peaks in an undulating graph. Taller sound waves have higher amplitudes and shorter ones have lower amplitudes. ANC headphones benefit from this by listening to the sounds around you and creating an opposing sound that neutralizes them.

ANC headsets come with various features to block out background noises like feedback microphones and ANC chipsets. These chips use algorithms that reverse the sound coming in and Headphones Sale then release a counter-signal, which is akin to firing antiballistic missiles at incoming warheads.

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

Although the technology behind ANC is impressive, it comes with a few drawbacks. The additional electronics required to make this technology function can add weight and bulk to your headphones. They also use more power, which can lead to a shorter life of the battery as well as 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 that is triggering these feelings, not the ANC headphones themselves.

The good news is that more sophisticated ANC headphones review are beginning to address some of these issues.
