Zoom Background noise suppression


The Zoom client has an option to take advantage of noise suppression. This eliminates the distracting noise that participants’ microphones may pick up. Background noise such as paper crunch, keyboard input, fan noise, and dog bark are excluded to provide a better meeting experience. By default, Zoom automatically performs background noise reduction, but you can change the options based on your environment and use cases.
