I got it. Use noise canceling headphones and modify your laptop. Current technology allows you to remove the top screen (on some monitor technology) and place in a cheap pair of glasses. The security filter you transferred from your laptop to your glasses will allow you, and you alone, to view your monitor. Microsoft is currently adapting this technology for the X box, to prevent screen cheating. Just tell the loud trio to tap you if they need your input and work through each meeting enjoying your favorite music and working on your laptop. This will allow you to negate the pain of your annoying coworkers and goof off at work if you need to.
