Noone gets to the top of the tree by sitting in the corner & waiting for things to happen. If you want to be the #1 then as soon as they mention a bad idea, immediately suggest reasons why & if you can't think of a bad reason, select the weakest point of the idea and heavily focus on it. Once you have done this, they will probably try and act smart and say "what's your big idea then?" then you have your time to convince everyone & as soon as any of the 'loud talkers' interrupt, don't let them by speaking louder and keep going they'll shut up and as soon as they do, rework parts of what you said whilst they were speaking gibberish back into your speech by saying "as I mentioned earlier but was interrupted by person X, Y and Z alongside..." and carry on speaking. Seriously, you can either sit in a corner or you can come out fighting so to speak, assert your authority and take the top spot.
