Inside voices for toddlers: tips?


I am trying to teach my 1.5 year old inside voices. She is very loud, at all times. At home I don't mind, but in public not so much. I know it will take a while for her to catch on, since at this point she gets louder instead of quieter. Probably thinks it's a game. Any tips to help her catch on quicker? I would like to start taking her to events at our local library but she is MUCH too loud for that lol
