When you buy any kind of headphones, the point of noise cancellation comes into play. Noise cancellation is one of the prominent features of modern headphones. Be it the wireless earbuds or the headphones, they all are nowadays having noise cancellation. There is nothing to confuse, as noise cancellation is what the name suggests. The noise cancellation is nothing but the technology, which digitally cancels the outside noise and lets you enjoy the music without external interruptions. If you are the one willing to know more about noise cancellation, then there are two types.

In this post, we are going to share detailed information on the Active and Passive Noise cancellation in the headphones. You’ll understand the details of active and passive noise cancellation and also the benefits of each type. So, if you are unaware of this technology and want to know which one is better for your needs, then you’ll get all the knowledge in this post.

What is Active Noise Cancellation?

Active noise cancellation is a technology, which is quite useful in reducing noise. With active noise cancellation, you can immediately reduce the outside noise while wearing the headphone. In this technology, small microphones have been used that capture the outside noise and reduce them digitally. So, while wearing the active noise cancellation headphone, the feed cancellation occurs digitally, and you won’t hear any sound from the outside. With the feed cancellation, forward-feed cancellation, and digital cancellation, the outside sound is masked properly, so you can hear the music or any audio with ease. Though note that the ANC tech comes in premium earbuds only.

Benefits of Active Noise Cancellation

Effective Noise cancellation in digital mode is the biggest benefit of the Active Noise Cancellation technology. The microphones picking up the external sounds and digitally filtering them so that you won’t hear anything through the headphone is the biggest benefit. The ANC or the Active Noise cancellation devices are highly useful in sound recording studios, heavy noise places like Airports and factories. Also, it’s highly recommended for outdoor communications, as the external noise doesn’t affect the communication.

What is Passive Noise Cancellation?

Passive Noise cancellation is the technique of isolating the sound from reaching your ears. The Passive Noise cancellation comes with similar technology but has fewer microphones to capture the external sound. Also, the sound isolation depends on the cushioning on the earmuffs, which isolates most of the sound. Passive Noise cancellation is great for normal usage. That’s why most of the basic headphones come with passive noise cancellation. They mostly rely on noise cancellation based on the cushioning, so you may hear some hissing sound while using such headphones. Also, the noise cancellation feature is only available in the headphones and not the earphones.

Benefits of Passive Noise Cancellation

Passive noise cancellation uses fewer amount of microphones. So, the users will have less sound isolation, but the battery life of the headphone will be increased. Less the fewer microphones, the more the battery life will be. The passive noise cancellation headphones are best for general usage. If you are living indoors and always use headphones for playing games and listening to music indoors, then it’s the best thing. Also, if you tend to use the headphones while driving, the passive noise cancellation headphones suit you the best, as they tend not to filter the horn noises helping you understand the traffic scenario.

Final Words

Most of the time, we cannot hear the music with headphones when there is excessive noise in the environment. Not all people can go to serene and calm places to enjoy the music. That’s why Active and Passive noise cancellation headphones are highly recommended. With the proper noise isolation, you can easily hear everything but filter out the external noise. Unfortunately, most people have no idea about the ANC and PNC technologies. So they choose the wrong type of headphone for their requirements.
