Most frequently read term in Noise Cancelling Headphones is CVC 6.0.
So I did some research for you and will be explaining you this 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 joy of listening music.
If you are at home, you get background noises of Children playing, Someone who is watching a TV, Cooking and so many.
If you are at Outdoors, you get other background noises like People crowd, Passing-by cars, which makes your phone calls on through headphones extremely difficult!
So What’s the solution?
CVC noise cancellation technology works in the background providing you Audio Enhancements and Noise Suppression.
CVC provides packet loss and bit error concealment.
CVC ensures Best possible call quality on Bluetooth headsets, Handsets, Hands-free Devices and Automotive Communication Devices.
How cVc 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 consists of modular suite of algorithms that works on:
- Enhancing voice communication :
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
