It is a holiday weekend, wait until everyone gets back.
Yes, it is difficult to control your speech if you depend on hearing it. I know lots of people in your situation. It must be natural to shout when you can't hear yourself. I believe the only way to control your volume is by practice and memorization.
If you are unsure, speak in a quiet voice, and if anyone doesn't get it, speak louder.

It happens to me all the time when I don't have my hearing aids in, as they help me judge my speaking volume. If I don't have them in, my husband is my "loud meter" to warn me to speak softer. :P But it sure is difficult when one can't hear oneself.

I think, like I when "instruct" doctors/nurses/whomever that in order for me to understand what they are saying, they need to face me, be fairly close (not across the room, i.e.), and speak up a bit. If someone told me I was talking too loud, I think I would also include that when explaining I'm HOH, etc. So they understand it's not that I'm "yelling" or using talking loud to express I'm mad at them, etc., but because I can't tell how loud I'm talking... People need educated all the time in the hearing world, it seems.
I also am careful about volume on TV or music, as I want to protect my husband's hearing. So I leave volume lower than I would use for myself, as I worry about him or our neighbors being subjected to too loud volume. I tend to keep volume lower and jack up my aids instead. I guess using special ear phones for TV or stereo would also work, to avoid having too loud TVs or stereos.
But, then, all of the above wouldn't apply if I were fully Deaf.... I guess the best we can do is communicate where we are as to our hearing, to the person we're trying to communicate with, and hope to educate and receive respect and consideration and some understanding.
