The Zoom client has options that allow the utilization of noise suppression, which can help remove distracting noises that can be picked up by participants' microphones. Background noise, like paper crunching, keyboard typing, fan noise, dog barking, and other noises will bee filtered out to create a better meeting experience. By default Zoom automatically does do background noise reduction. However, the option can be changed to be more or less aggressive based on the environment and use case.
