Small sounds make me jump and scare me?

I don’t think I was always like this, but small noises like the ice maker, things falling, one of my dogs barking when I’m not expecting, etc., kinda startle me and I jump? I thought I might just be sensitive to noise all of sudden, but then I was listening to music and I had been listening to a song I’ve heard dozens of times before and one part of the song startled me and I ripped off my headphones. That’s when I thought maybe it wasn’t normal, but idk, it’s not something I see people talk about. I do have PTSD from sexual trauma, but I don’t know why a symptom like that would show up all of sudden and my trauma has nothing to do with loud noises.

Anyone else experience this?
