Run the opener anyways! Look I got to different clubs and bars all the time that can be so loud the floors are vibrating with the music! You have to learn how to project your voice without yelling.
Style gives a good exercise on his "Rules of the Game" 30 day challenge. He says take a tape recorder. First stand a few feet away and practice your openers. Then stand ten feet away. Then stand across the room. You are learning to project your voice without yelling at someone. Play yourself back and see how you sound.
You can do it!
