But what exactly does noise cancelling mean? How does it work? And what are the different types of noise-cancelling headphones available?

In this article, we will explore the world of noise-cancelling headphones and answer these questions and more. Whether you’re a frequent traveler, a music enthusiast, or someone who simply craves a moment of silence, understanding noise-cancelling technology can greatly enhance your listening experience.

So, let’s dive in and discover what noise cancelling really means and how it can make a difference in our daily lives.


How Does Noise Cancelling Work?

Noise-cancelling headphones use a combination of advanced technology and clever design to reduce or eliminate unwanted background noise. The key concept behind noise cancellation is to create an “anti-sound” that effectively cancels out the incoming noise.

Active noise cancellation (ANC) is the most common technology used in noise-cancelling headphones. These headphones are equipped with tiny microphones on the earcups that pick up external sounds. The headphones then produce a sound wave with the exact opposite phase to the incoming noise, effectively canceling it out. This process is known as destructive interference, where the peaks and troughs of the sound waves cancel each other out. The result is a quieter and more peaceful listening experience.

It’s important to note that noise-cancelling headphones work best for steady, low-frequency sounds like the humming of an airplane engine or the rumble of a train. These constant sounds are easier to cancel out compared to sudden, sharp noises like a door slamming or a loud conversation.

Passive noise cancellation, on the other hand, relies on the physical design and materials of the headphones to block out external noise. Over-ear headphones with closed-back earcups provide a physical barrier that helps reduce external noise. The padding in the earcups also helps to create a seal around your ears, preventing sound from leaking in or out.

Combining active noise cancellation with passive noise cancellation provides the best results. The active noise cancellation technology actively cancels out external noise, while the passive noise cancellation design blocks out additional noise.

Overall, the technology behind noise cancelling headphones is truly remarkable. It allows us to create our own personal oasis of tranquility amidst a noisy world, immersing ourselves in the sounds we want to hear while blocking out the ones we don’t.


Active Noise Cancelling vs Passive Noise Cancelling

When it comes to noise-cancelling headphones, there are two main types: active noise cancelling (ANC) and passive noise cancelling. While both technologies aim to reduce external noise, they differ in how they achieve this.

Active noise cancelling headphones utilize advanced technology to actively cancel out unwanted noise. As mentioned before, these headphones use built-in microphones to detect external sounds. The headphones then generate sound waves with inverted phases to cancel out the incoming noise. This process effectively reduces or eliminates the external noise, allowing you to focus on your audio content or enjoy a moment of peace.

Passive noise cancelling, on the other hand, relies on the physical design and materials of the headphones to block out noise. Over-ear headphones with a closed-back design provide a physical barrier that seals in sound and prevents external noise from entering. The padding in the earcups also helps to create a tight seal around your ears, further reducing noise leakage.

While active noise cancelling headphones are more effective at reducing low-frequency constant noise like airplane engines or train rumble, passive noise cancelling headphones provide excellent noise isolation from a wider range of frequencies, including higher-pitched sounds or sudden noises.

One advantage of active noise cancelling headphones is their ability to let you customize the level of noise cancellation. Many active noise cancelling headphones come with adjustable settings that allow you to control the amount of external noise you want to cancel. This can be particularly useful if you still want to be aware of your surroundings or need to hear important announcements while wearing the headphones.

Passive noise cancelling headphones, on the other hand, do not require any power source or batteries to operate. They also tend to be more affordable compared to active noise cancelling headphones. This makes them a popular choice for individuals who want to enjoy enhanced audio experience without the need for additional technology.

It’s important to note that the effectiveness of noise cancellation can vary between different headphone models and brands. It’s always a good idea to read reviews and do some research before making a purchase to ensure you choose the type of noise cancelling that best suits your needs.
