 And so let's say I'm answering a question. My light is green and I'm speaking. Phil's microphone is off and his green lights are not illuminated. He's going to interrupt me as I'm speaking and this is what it will sound like. My volume remains constant while Phil's interruption can be difficult to understand. Let's try the opposite. My microphone is now on. Victor's microphone is off and he's going to interrupt me. My volume remains constant while Victor's interruption can be difficult to understand.
