When we use Bluetooth headsets or earbuds to talk on the phone, it’s partly to cut down on noise from the environment. You may have noticed, though, that not all headphones are good at giving you this much-desired clarity. Clear Voice Capture (cVc) noise cancellation is a technology that has been getting a lot of attention recently. We’ll talk about what cVc noise cancellation is, how it works, and how to use it in this article.
What is noise cancellation with cVc?
If you’ve ever tried to talk over the noise of a construction site, you know how hard it can be to make yourself understood.
Qualcomm made Clear Voice Capture (cVc) noise cancellation, which is a way to block out noise. It uses complex algorithms to remove background noise from speech and make voice communications crystal clear for people who have trouble hearing or who are in noisy places like airports or trains.
It makes the microphone pick up less noise, so the person on the other end hears less background noise. Noise-cancelling technology like cVc is great for noisy places because it blocks out background noise so that even in the noisiest places, calls are clear.
How does noise cancellation with cVc work?
cVc noise cancellation technology is based on algorithms that work to block out background sounds like ambient noise, traffic noise, and other people talking in the background. With cVc, the person on the other end of a call can hear you clearly even if you’re driving or in a loud place.
When you talk into the microphone of a device with cVc noise cancellation, its algorithm starts to separate what you’re saying from all the other sounds around you. Then, it makes a profile that it uses to cancel out other sounds so that voice calls are crystal clear.
The better cVc noise cancellation works, the longer you talk on a call. As the call goes on, the algorithm learns more about the background noise and changes to better block it.
How cVc Noise Cancellation Works
cVc devices have the following audio processing features built in:
- Automatic controls for gain
- Equalizers for send and receive
- Comfort noise
- Howling take charge
- Processing that doesn’t follow a straight line
- Adaptive equalizers
- Ways to save electricity
- Mixing of auxiliary streams
- Frequency made speech easier to understand.
Most Bluetooth headphones and earbuds use cVc noise cancellation technology. You can also find it on cell phones, laptops, and other devices with a microphone or speakers.
cVc Noise Cancellation Technology’s Pros and Cons
There are many good things about cVc noise cancellation technology. One of the biggest benefits is that it cuts background noise by 20–40 dB, which makes 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 when speaking into a microphone or listening through speakers. Lastly, cVc noise cancellation technology is helpful because it makes it so people don’t have to manually change the levels or balance of their devices’ audio settings.
Noise-cancelling technology with cVc has some drawbacks
After reading about the features and benefits of cVc noise cancellation, you might be thinking about getting a pair of headphones with this technology. But it’s important to know that this technology does have some problems.
First of all, headphones with cVc are more expensive than normal headphones. Some of them cost as much as $400, but cheaper ones cost about $100.
The battery life is another bad thing about cVc headphones. Because noise-cancelling requires power, cVc headphones tend to use more power than regular headphones.
Should You Get a Pair of cVc Headphones?
You are the only one who can decide if you want to buy a cVc headphone or not. But if the price and battery life don’t bother you, there’s nothing stopping you from getting one.
