i think that there are microphones in the crowd/near the crowd that they use for sending crowd noise to the house. davina's microphone probably wouldn't pick up crowd noise. like at a music concert, the singers microphone doesn't pick up any crowd noise, regardless of how much there is!

so basically, when davina talks to thw house and it's quiet, they are only sending davinas microphone. i very much doubt that the crowd were quiet, they really seem to dislike lea!
