Noise cancellation in headsets: What is it, and how exactly does it work?

Noise cancellation is very much the tech expression of today – at least in the audio world. Every headphone producer seems to be speaking about Active Noise Cancellation (ANC), which pleases us greatly at Jabra because we have a long history of engineering such sound solutions.

Noise cancellation in headsets: What is it, and how exactly does it work?

We started developing ANC two decades ago, and have today enhanced and improved this technology along with the digital signal processing (implemented via a two-microphone solution) now found in the Jabra Evolve 75.

But what is noise cancellation? How does it work, and how can it help you work? The first thing to note is that there are two types of cancellation – passive and active – and both are important features of the Evolve 75. Continue reading

ANC headsets aren’t all the same: Headset design matters

Active noise cancellation (ANC) has become a popular feature in music headsets. Many headsets now boast ANC, but not all of them are created equal. Let’s see why.

This is the second part of our look at why not all ANC headsets are alike. In the first part, I’ve talked about how active noise cancellation itself comes in a few different flavors: feedforward, feedback, and hybrid. The hybrid approach works best but costs the most.

But even going with the expensive hybrid ANC solution doesn’t guarantee that you’ll get the perfect ANC headset. Why? Because aside from the ANC technology itself, there’s also the matter of how the headset is designed. Continue reading

Active noise cancellation (ANC) has become a popular feature in music headsets. Many headsets now boast ANC, but not all of them are created equal. Let’s see why.

As I have briefly mentioned in an earlier post, ANC is all about generating “anti-noise” that mirrors and cancels the ambient noise. (The technical term for this is “destructive interference,” which makes ANC sound like a bit of a badass fighting for the good guys.)

In an ideal world, ANC should result in a completely noise-free experience for the one wearing the headset. Spoiler alert: We don’t live in an ideal world. Continue reading
