What Is cVc Noise Cancellation? How Does It Work?


Part of the reason why we use Bluetooth headsets or earbuds to make calls is that we’re trying to reduce interference from surrounding sounds. However, you’ve probably noticed that not all headphones are good at delivering this much-sought clarity.

Clear Voice Capture (cVc) noise cancellation is a noise suppression technology that’s been making waves of late. In this article, we’ll discuss what cVc noise cancellation is, how it works, and how it’s used.

What Is cVc Noise Cancellation?

If you’ve ever had to speak over the background noise of a construction site, you know how hard it can be to communicate clearly in a noisy environment.

Clear Voice Capture (cVc) noise cancellation is a noise suppression technology developed by Qualcomm. It uses sophisticated sound processing algorithms to remove background noise from speech and provide crystal-clear voice communications for hard-of-hearing people and those in noisy environments such as busy airports or trains.

It reduces the noise picked up by the microphone, thus reducing background noise for the person on the other end. cVc noise-cancellation technology is ideal for noisy environments because it blocks background noise to make clear calls, even in the noisiest places.

cVc noise cancellation technology relies on algorithms that work to suppress background sounds such as ambient noise, traffic noise, and other people talking in the background. cVc makes it possible for the person on the other end of a call to hear you clearly, whether you’re on the road or in a loud environment.

When you speak into the microphone on any device equipped with cVc noise cancellation, its algorithm begins separating what you’re saying from all the other sounds around you. It then creates a profile with which it uses to cancel out other external sounds, delivering crystal clear voice calls.

The longer you stay on a call, the better cVc noise cancellation works. The algorithm understands the environmental noise as the call goes on, adapting and blocking the noise more effectively.

Features of cVc Noise Cancellation

Audio processing features embedded in cVc devices include;

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

cVc noise cancellation technology is mostly used in Bluetooth headphones and earbuds, but you’ll also find it on mobile phones, laptops, and other electronic devices that use a microphone or speakers.

Benefits of Using cVc Noise Cancellation Technology

cVc noise cancellation technology has many benefits. One of the biggest advantages is that it reduces background noises by 20-40 dB, making it easier for the person on the other end of the line to hear you clearly without static interference.


It also helps users reduce sudden sounds and vocal distortions while speaking into a microphone or listening through speakers. Lastly, cVc noise cancellation technology is beneficial because it reduces the need for users to adjust levels or balance audio settings on their devices manually.

Cons of cVc Noise Cancellation Technology

Having touched on the features as well as the benefits of cVc noise cancellation, chances are you’re now considering getting a headphone equipped with this technology. However, it’s important to know that this technology is not without its downsides.

To start with, headphones equipped with cVc are more expensive compared to regular headphones. Affordable versions go for about $100 while some others cost as much as $400.

Another downside of cVc headphones is battery life. Because noise-canceling requires power, cVc headphones tend to consume more power than regular everyday headphones.

Should You Buy a cVc Headphone?

The decision of whether to buy a cVc headphone can only be made by you. However, if the price and battery life don’t bother you, there’s really nothing stopping you from getting one.
