Active Noise Cancellation (ANC)


If we talk about active noise cancellation, it uses quite advanced technology to actively combat noise. It analyzes and tests the sound patterns of all incoming noises that disturb the interaction and calling process and then creates a mirror that gives an anti-noise warning to cancel it. As a result, you will dramatically reduce noise levels.

 

This type is wonderful for continuous and low-frequency sounds, such as fan noise, engine sounds, and humming like TV shows and similar to production tunes.

 

Passive Noise Cancellation (PNC)


This type defines noise cancellation accomplished by the physical characteristics of the headset, including the style, design, and accessories used. 

 

Passive noise cancellation is preferable to erasing irregular and high-frequency noises that prevent users from sharing something important. While this type is commonly used in music headphones, some new and modern office headsets are also built to protect your ears and block unwanted external sounds.
