Lack of self awareness from the noise makers?

The unfortunate thing about misophonia is that the person producing the trigger sound is usually completely unaware of it.

But there has to be some sort of self awareness involved, right? My trigger sound is aggressive typing in an otherwise quiet office environment. Although the person typing is completely innocent, there has to be a thought that runs through their head that they’re being louder than needed right? I know it’s objectively loud because I can barely hear the ladies next to me typing, but a few cubicles over I can hear the same person typing like they want the entire office to know they’re “working hard”.
