The two sound waves effectively cancel each other out, both becoming inaudible.Ī graphical depiction of active noise cancellation. When AI knows what sounds it needs to suppress, it can then employ active noise-canceling to eliminate that background noise.Īctive noise-canceling happens when a machine detects the noise it needs to cancel, then generates its own noise that is out of phase with the background noise. This distinction can be difficult for a machine to recognize under normal circumstances, as the human voice shares a similar frequency with many other natural sounds. How Does Noise Cancelling AI Work?Įssentially, the noise-canceling AI has to learn the difference between the sound of a human voice and any sort of background noise that it may encounter.
Noise suppression has been an optional setting in many calling apps for a number of years but very rarely is it 100% effective. Some calling programs have introduced noise-canceling AI as an option for users to reduce background noise in their virtual calls and make these calls more efficient and productive. But we’ve also all faced the noisy challenges that come along with these calls - a colleague’s dog barking in the background, your neighbor loudly mowing their lawn, or even just someone on your team having a particularly noisy keyboard. With the pandemic having changed work life as we know it, many of us have used programs like Zoom or Slack to call our colleagues and discuss projects.
