How do noise canceling headphones work

If you’re looking for a way to reduce distractions and focus in noisy environments, noise-cancelling headphones may be a good option. But how do noise canceling headphones work?

These headphones work by using various technologies to block out external noise. This can help you to concentrate on what’s essential and make your work or leisure activities more enjoyable.

In this article, we’ll take a closer look at how noise cancelling headphones work and their benefits and types.

How Do Noise Cancelling Headphones Work?

There are a number of different technologies used to create noise-cancelling headphones, but the most common is acoustic engineering. This involves using sound waves to cancel out other sound waves.

The technology works by stimulating certain areas of your ear with low-frequency sound waves. These vibrations help to reduce the impact that external sounds have on your hearing.

This means that you can hear more clearly and without being disturbed by outside noises.

Benefits Of Noise Cancelling Headphones

Aside from reducing distractions and helping you to concentrate, noise-canceling headphones have other benefits. These include:

  • Improved communication abilities.
  • Noise-cancelling headphones can provide an enjoyable listening experience. This is because they reduce the level of external noise while preserving sound quality.
  • They can be helpful if you have a hearing impairment or sensitivity to loud noises.
  • They can also help improve your quality of sleep by reducing the amount of noise that reaches your brain during the night and wake up refreshed in the morning.

How Do Headphones Cancel Outside Noise?

When you put on a noise cancelling headphone, the acoustic engineering technology inside works to reduce or eliminate outside noises. This can be done in different ways:

Active Noise Cancellation

This involves using microphones and other sensors to detect and analyze sound waves. When the headphones encounter a loud noise, they will automatically activate filters that block out the sound.

Passive Noise Cancellation

In contrast, passive noise canceling headphones rely on factors such as your head size and ear shape to reduce external sounds.

They use materials like leather or foam padding around each earcup to help block out outside noises.

There are many different types of noise-canceling headphones available on the market, each with its own advantages and disadvantages.

It is essential to choose the right style for your needs in order to get the best possible experience.

Types Of Headphones Best For Noise Cancellation

The different types of headphones that are best suited for noise cancellation include:

Over The Ear Headphones:

These are the most popular type of noise-canceling headphones, and they offer the best overall sound quality.

They’re also the least portable, so if you’re looking for a headphone that you can take with you wherever you go, over-the-ear headphones aren’t your best option.

In-Ear Headphones:

In-ear headphones are perfect for people who want to avoid being seen wearing noise-canceling headphones, as they’re usually less conspicuous than over-the-ear or audiophile types of headphones.

They also tend to offer better sound quality than other types of noise-cancelling devices, but they can be more difficult to get comfortable with over time.

On-Ear Headphones:

On-ear headphones are a good option if you want to be able to move around while wearing your noise-cancelling headphones.

They typically offer better sound quality than other types of noise-canceling devices, but they don’t usually have the best range.

Quality Noise Cancelling Headphones:

Quality noise Cancelling headphones will have superior acoustic engineering technology inside them to produce clearer sound quality while reducing outside noises. Ultimately, the type of headphones you choose is based on your preferences and personal needs.

Tips For Choosing A Good Pair Of Noise Cancelling Headphones

Follow these tips to choose a good pair of noise canceling headphones that will give you the best overall sound quality:

1. Identify Your Noise-Canceling Headphone Needs

If you want them primarily for travel or general listening around town, a cheaper option may be enough – such as earbuds or in-ear headphones. If you want something more specific and professional, go for Noise Cancelling Headphones designed specifically for that use. 

2. Consider Your Budget

Noise Cancelling Headphones come in all price ranges, so don’t be afraid to start out with a lower-end option if you need help saving money down the road. Active noise canceling models can be quite expensive though – especially if they include features like ANC ear cups or a built-in mic.

3. Consider What Features Are Important To You

Some people simply want a good pair of earbuds that do the job, while others may be looking for headphones with advanced noise canceling technology and an intelligent assistant like Apple’s AirPods.

Not all Noise Cancelling Headphones offer both features, so it’s worth doing some research before making your purchase.


I hope you’ve found this article helpful. Now you know how noise-canceling headphones work? To conclude, Noise canceling headphones are a great way to reduce the level of outside noise while preserving sound quality.

They can be helpful if you have hearing impairments or sensitivity to loud noises.

Lastly, they can also help improve your quality of sleep by reducing noise that reaches your brain during the night.

The acoustic engineering technology inside can make it easier for you to fall asleep and wake up refreshed in the morning.


Do noise Cancelling headphones really work?

Yes, noise-cancelling headphones do work. They use different technologies to reduce or eliminate outside noises.

Does noise cancelling hurt ears?

No, noise cancelling headphones don’t actually ‘cancel’ out the sounds. They instead use various technologies to reduce or eliminate outside noises. This can include using microphones and acoustic filters.

Why can I still hear noise Cancelling headphones?

There are several reasons you may still hear noise cancelling headphones. Most likely, it is because the microphones and acoustic filters aren’t perfect.

When outside sounds enter the headphones, they can be ‘cancelled’ but some of the sound waves will still reach your ears.

This can result in a faint background noise that you can sometimes hear when wearing noise cancelling headphones.
