what is passive noise cancelling

You must have heard the term noise cancellation technology in headphones and earphones. These headphones offer great features and noise-cancelling technology for better listening and calling experience.

There are some basic types of noise-cancelling headphones such as Active Noise Cancellation (ANC), Passive Noise Cancellation (PNC), and Adaptive Noise Cancellation.

Among all Passive Noise Cancellation headphones are assumed one of the most affordable and comfortable. So, keep reading to understand everything about Passive Noise Cancellation headphones. 

what is passive noise cancelling?

Passive Noise Cancellation or you can say Noise isolation headphones as these types of headphones do not use any specific technology to cancel the ambient noise instead they use their physical material and shape to block out the noise.

Passive Noise-Cancelling headphones are not embedded with microphones or any type of built-in technology but still, they can enhance your listening experience.

Another reason why passive noise-cancelling headphones are best is that you don’t need any special or additional technology to enjoy music and to take advantage of Passive Noise isolation headphones. 

Passive Noise isolation headphones are also inexpensive and do not drain as much battery as Active Noise Cancelling headphones. 

There are many more amazing facts about Passive Noise Cancellation headphones that we will discuss further in detail but first let us tell you the working process of Passive Noise-Cancelling headphones for better understanding. 

How does Passive Noise Cancellation headphones work?

Passive Noise Cancelling headphones come with earmuffs and comfortable padding that fits your ears perfectly. Through the shape, passive noise-cancelling headphones prevent outside noise from entering your ear canal.

Almost all the headphones and earbuds are equipped with passive noise isolation as the amount of noise cancellation offered by the physical design and padding of the passive noise isolation headphones is matchless and beyond comparison. 

Ear cups design acts as a physical barrier to prevent the environmental noise from interrupting your time. It works exactly like when you cover your ears with your palm to decrease the noise level.

Every headphone has passive noise isolation technology, however, a little amount of sound may still leak that you can improve by switching to thick insulating materials ear cups of your headphones.

Passive Noise Cancellation headphones are especially great for you if you want to isolate the outside noise and still want to be able to hear others as they offer better sound quality.

This way you can listen to music for a longer time at a low volume without harming your ears. 

Furthermore, passive noise isolating headphones not only make your music time richer but enhance the calling quality as well.

Whether you are at a coffee shop or traveling on a bus or train, you can talk over the phone very smoothly and make the conversation clearer.

How much noise can be reduced with Passive Noise Isolating headphones?

Passive noise-isolating headphones can not remove the ambient sound entirely but enough for you to talk over the phone and listen to music that is around 30db to 40db. Understand it this way- suppose a car that is around 50-60 meters away from you, produces around 80db of noise and noise isolating headphones will make it half for you.

Whereas, some sounds like whispering, murmuring and talking in a low voice produce around 20db noise which means that cannot disturb you at all. When someone is communicating in a normal voice, you will be able to hear that with your headphones on.

The amount of noise these headphones can reduce also depends on the volume level of your headphones which means the louder the music the less you can hear. And also note that these dB measurements are not accurate as the frequency of sound is greatly responsible for sound isolation. 

Passive Noise Cancellation Vs Active Noise Cancellation – Which is better?

Passive Noise Cancellation and Active Noise Cancellation both technologies offer the same noise-cancelling to prevent outside noise, however, the method is quite sane for both. Active Noise-cancelling headphones use advanced technology and microphones to stop the ambient noise whereas Passive Noise-Cancelling headphones use materials such as padded ear cups and shapes to isolate the background noise.

Due to the advanced technologies, Active Noise Cancellation headphones drain so much battery and are also quite expensive but they still can not block the loud noise entirely.

Active Noise-cancelling headphones require special mics that filter the noise and neutralize it according to the frequencies of the sound waves.

Passive Noise Cancelling headphones rely on the hardware and shape of the headphone which means no battery drainage and they are also less expensive and reliable. 

So, now that you know the difference between Passive Noise Cancellation and Active Noise Cancellation, you must be scratching your head thinking which is better, well, here are some points to figure it out:-

  • Sound quality:- Active Noise Cancellation headphones produce sound waves which create sensation to block out the ambience noise and hence, effect the sound quality and your listening experience as well. 

Passive Noise isolation headphones use earmuffs and shape to prevent the environmental noise that means it doesn’t create any sound waves, so they do not affect the sound quality at all.

  • Comfort:- Active Noise Cancellation headphones put pressure against your ears to cancel the noise and Active Noise-cancelling headphones are also not designed to fit perfectly on ears which is why your ears get hurt very quickly.

Passive Noise-cancelling headphones can fit comfortably over ears and they are also very flexible. So, when it comes to comfort, Passive Noise Isolating headphones are far better than Active Noise-cancelling headphones.

  • Battery life:- Active Noise Cancellation headphones consume more power as they create noise to cancel the ambient sound and other electrical features also drain battery life.

Passive Noise Isolating headphones only use Bluetooth and to function, so, they do not need that much power to operate which results in longer hours of playtime.

  • Safe for ears:- Active Noise Cancellation produces an equal amount of sound to stop the ambient noise even if you are listening at a very low volume, so, it doesn’t do any good.

Whereas Passive Noise-Cancelling headphones don’t use any technology or frequency to block the noise, so, they are safer than Active Noise-cancelling headphones. 

  • Cost:- Cost is the biggest difference between Active Noise-cancelling and Passive Noise Isolating headphones. Noise cancelling headphones are quite pricey and also not very much reliable whereas, noise isolating headphones comes at a very reasonable price with great design and comfort.

You must have figured it out by now that Passive Noise Isolating headphones are better, durable, safe and also the safest way to reduce the background noise by just covering your ears.
