I can't handle people who shatter as soon as a voice is raised. I am a loud. I was raised in a loud environment. It might be a tad cultural, as well. I have been in a relationship with someone who found that intensely stressful, and I in turn found it stressful to try to curb my natural impulses. In the end, I think it was just a very incompatible situation.
I imagine it's how people are built, combined with how they were raised (as with most personality traits).
For example, I came up in a house where if someone was raising their voice that meant something was wrong. It probably meant that the situation was about to be escalated if whoever was being yelled at didn't capitulate pretty quickly. So, in my relationships, I consider raising my voice, or having someone raise their voice at me, in anything but
extremely rare and contextually reasonable occasions, to be unacceptable, and therefore (as you said), we are incompatible.
In my world, I still think that someone getting "pissed off" is a sign that something is going on. I understand that some people talk louder and more frequently than others, but what is there to be angry about? So angry that there needed to be raised voices or berating going on? That is an issue, in my opinion, no matter how comfortable someone might be with the volume of the voices involved. There is most likely a glitch in the worldview of one or more involved parties (probably everyone involved).
My last long-term relationship was an example of a poisonous involvement which should have been aborted. I raised my voice frequently in that relationship; we had fights which were heated and mean; this was a great sign that we had no business associating with each other. I broke up with her, scrapped her from my life entirely, and I have been a demonstrably better human for it.
