noise suppression check

Before joining a meeting, I always run a quick noise suppression check to make sure my background isn't distracting everyone else. It's basically testing if the mic picks up my typing or the hum of my fridge, and adjusting the filter settings until only my voice comes through clearly. That way, no one hears the dog barking or the coffee machine.
