If you’re looking for a way to reduce ambient noise without completely blocking it out, noise cancelling headphones can be a godsend.
They’re designed to tune out different frequencies of sound by using deep bass waves.
In this article we shall figure out whether noise-canceling headphones are worth buying & safe for use as well.

What is Noise Cancellation?
Noise cancellation acts like a sonar, using the relative positioning of the listener and sound source to block them out. Your brain transfers the sound waves to different parts of your skull based on where they’re coming from.
The side of your head will have a stronger signal from one source if it’s closer. So, by focusing more on what you’re listening to and less on the ambient noise, you can better hear things that are important.
This technology can be used in headphones and earbuds, as well as earphones and hats. Some devices, such as high-end headphones and advanced noise cancelling earbuds , use mini microphones to record the necessary frequencies of your surroundings.
They then output those frequencies, creating a “cancellation wave” that fends off the background noise. This is more effective than passive noise control, which just blocks out certain sounds.
It’s important to note that these devices don’t create complete silence – you’ll still hear a faint noise – so it’s not ideal for concerts or loud bars.
How Noise Cancelling Headphones Work:
The design of noise-cancelling headphones relies on blocking out different frequencies of sound. You’ll typically focus on one frequency, like the bass, to reduce the number of “annoying” sounds you hear. But how do they work? How do they reproduce specific frequencies? Let’s dive into the science!
First off, there are three main parts to your body that respond to sound waves: your ear, your eardrum and an inner ear. There are also two parts of the ear that you might not think about: your stapes and your oval window.
Sound travels through the air, but it can’t travel underwater. So, when you’re in the water, your stapes will push against your oval window to create vibrations that are transmitted into your inner ear. This creates an echo that changes depending on the resonant frequency of the medium.
You might have heard about bone conduction technology before if you’ve ever worn headphones while swimming or running. Sometimes people use this technology to listen to music or podcasts while they work out because it doesn’t block their ears with headphones.
Bone conduction allows you to hear both the ambient noise around you and what you’re listening to at the same time.
There are two main types of noise-cancelling headphones:
Active Noise Cancellation:
The first type is known as active noise cancelling, or ANC. This system creates sound waves that are opposed to the original sound waves. Having two high frequencies can cause high-frequency health problems, so this isn’t ideal for every consumer.
ANC uses miniature microphones to record the frequencies of ambient sounds, so they have to use batteries for power.
Passive Noise Cancellation:
The alternative is passive noise control, which just blocks out all sound with earmuffs or earbuds . These devices rely on acoustics to block out all unwanted sound without creating a “cancelling” wave.
How to Improve Your Noise Cancelling Headphones Experience:
Noise cancelling headphones, unlike passive noise blocking earbuds, don’t necessarily have to be good. They just have to work well enough that you can ignore the rest of the world, which isn’t necessarily ideal. So, here are some ways you can make your experience better:
Pick the right size for your ears:
If you’re wearing premium noise-cancelling headphones and they feel like they’re pressing against your ear, they may not be the right size for you. Some people might have a larger ear canal to start with, while others might need a smaller size. They also vary from person to person.
Get a storage case:
If you decide to keep your headphones in a case or backpack, they’ll be more likely to stay clean and sound better when you listen to them. Also, it’s much easier if they don’t get tangled when you’re not using them.
Find different tips for your noise-cancelling headphones:
For some people, cheap noise cancelling headphones feel really tight when they’re in earbuds or earplugs. Others experience this problem with their super-closed earbuds that seal out the outside world.
Conclusion:
As you can see, noise-cancelling headphones use special technologies to keep your ears comfortable and your music clear. If you’re interested in purchasing a pair, do some online research and compare different pairs of passive or active noise cancelling headphones to see which is the best fit for you.
