I find myself reacting to the smallest thing by raising my voice, unless I'm consciously trying not to.
I end up shouting like a fishwife to make myself heard or to tell someone to do something for the 100th time, or to stop big brother beating up baby sister or to stop him pulling a whole load of cake mixture off the table ...
I hate it. it makes my head hurt. And I am always saying 'sorry I shouted' a few minutes later. It's not even that I have an especially fiery temper, I just can't help shouting! How do I stop doing it?!
