I think your ideas about why it changed are legitimate. Part of it probably has to do with the fact that you're now able to control your own space and decide how much sound you have bombarding you. It's great that your family is supportive and complies. In our household, there can be a good deal of sound from just three of us, but whenever anyone needs quiet (like when I'm writing a poem, or when my son is recording sound for an animation) we all go on silent running for a while.
