What is Noise Cancellation?
Basically Noise Cancellation means cancelling out the unwanted external noises using noise control mechanisms. Basically noise cancellation can be sub-divided into two categories which have been out lined below:

  • Active Noise Cancellation: This is the advanced technology used particularly by noise cancellation headphones. Under active noise cancelling there is an inbuilt circuitry inside the headphones which analyze the wave length of the noise coming in. Post Analyzation a mirror signal to the noise with negative wave length is induced into the output sound; thus, cancelling the noise and as a result you get to hear remarkably clear music.

  • Passive Noise Cancellation: This is not basically anoise cancellation technique but it is more of a sound proofing technique.Under this the passive noise cancellation headset for music is built so as toenvelop your ears completely. As a result, the outside noise is cut to a considerable level; how ever, this is not at par with active noise cancelling technique.

What is CVC 6.0 ?

Yes, Sound Cancelling Headphones is one of the highest selling item in world! and every-time you look at the headphone specifications you might have come across a term Noise Cancelling Headphones featuring CVC 6.0 Noise suppression.

I think it is necessary to know meaning of cvc and its utility and is it MUST for my headphone? if yes in what way.

So here is my research where I will be explaining you CVC 6.0 noise reduction term indetails.

Why you need Noise Cancelling for Headphones ?
  • Either you are using the headset at Home or Outdoors, different environment noises disturb your, specially during calls making conversation difficult at times. Mostly person at the other end of call will hear roar,disturbing noise which will be filtered by this intelligent system.
  • If you are at home, you get background noises of Air conditioning, washing machine, Children playing, Someone who is watching a TV, Cooking and so many.
  • If you are at Outdoors, you get other background noises like Wind noise, People crowd buzz, Passing-by cars tire  roar, Boom of jet engines, which makes your phone calls on through headphones extremely difficult.

So What’s the solution? CVC by Qualcomm ?
It is one of the best & most affordable system making telephonic conversation over your headphone super silent! In simple words, the person at the other end of call will feel like you are talking to him from a quiet indoor space! Wonderful technology making call quality super in the cheapest entry level earbuds & headphones. Thanks to Qualcomm engineering research center for that.

What is CVC 6.0 Noise Cancelling Technology ?
  • CVC noise cancellation technology by Qualcomm works in the background providing you Audio Enhancements and Noise Suppression to the near and far end.
  • CVC provides packet loss and bit error concealment.
  • In tern, CVC noise reduction ensures Best possible call conversation quality on your Bluetooth headsets, Landline Handsets, Hands-free Devices and other Automotive Communication Devices.

  How CVC Noise Cancellation Works ?
During voice call, the microphone picks up all background noises as well as your voice too, in this scenario, CVC intelligent algorithms comes in to picture, they will Enhance the Voice Quality during transmission from your headset, as well as do the same during reception at the other end headphone (if that headset is CVC enabled)

Further to this CVC noise reduction consists of modular suite of algorithms that works on:

  • Enhancing voice communication: Crystal Clear Sound output
  • Examples like acoustic echo cancellation and noise suppression, which can be applied in a granular fashion to as per the customized requirements of the gadget.

  • CVC separates out the voice signals of interest:
  • Other logic or algorithms in market which are used to suppress noise, CVC uses proprietary signal extraction techniques, it understands the way human speech is heard and processed! and employs an active and self-adaptive system.

CVC Features
  • Automatic gain controls
  • Send/Receive equalizers
  • Comfort noise
  • Howling control
  • Nonlinear processing
  • Adaptive equalizers
  • Power savings techniques
  • Auxiliary stream mixing
  • Frequency enhanced speech intelligibility

Is it Safe to Use Noise Cancellation Head Phones ?
This is a common question of majority of music lovers. Let me answer this for you. It doesn’t matter whether you use noise cancellation headset for sleeping or music or when outdoors; these headphones, unlike cell phones, don’t emit low level radiation hence they are very much safe to use.

Actually using noise cancellation headset for outdoor for eliminating external noise could be quite beneficial as continuous exposure to high levels of noise can be quite detrimental to health. Also your kids won’t raise the volume much if they are able to hear their songs clearly while using noise cancellation headset for music.

What are the Pros & Cons of using Noise Cancellation Earphones ?
Below I have out lined some major pros as well as cons for using noise cancellation headsets:
  • Effective sleep aid for those having trouble sleeping in noisy environments or are suffering from insomnia. Since they cut out the external noise, whether it is sound of air plane or your fellow passengers talking, you can use your noise cancellation headset for sleeping.
  • Since you don’t require to keep the volume high you can preserve your ear health.
  • If you are a travel junkie these headsets are the must have accessories in your backpack to cut out the noise of train, plane or bus.
  • Noise cancellation headsets are quite expensive and you have to shell out a good amount of bucks to buy a pair for your ears.
  • The power usage is quite high in case of active noise cancelling. As a result battery levels might drop quickly. Plus they won’t function as an ordinary headset in case the battery dies.
  • These headphones tend to be bulky as they need to have circuitry for active noise cancelling.
  • The audio quality may be decreased by the noise-cancelling circuitry plus you might hear a high frequency screeching sound.

Thank You

That's all for today. If you have any doubts about these steps you feel free to ask in comment section.
