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 came 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 cvc6.0 noise reduction term in details.
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 into 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.
- Automatic gain controls
- Send/Receive equalizers
- Comfort noise
- Howling control
- Nonlinear processing
- Adaptive equalizers
- Power savings techniques
- Auxiliary stream mixing
- Frequency enhanced speech intelligibility
