I definitely don’t have full-on misophonia, but some noises that irrationally drive me insane - what I can think of off the top of my head...
My dad chews with his mouth open a little bit, so I hear him chewing (but the noise of someone chewing with their mouth completely closed doesn’t bother me, is why I really don’t think I have misophonia), and also a tendency to smack his lips while eating.
Whistling - any and all whistling just makes me instantly irritated.
People walking while wearing flip-flops.
Most pop music - I got way overdone on that in college because anywhere there was music playing on or near campus, there was a 98% chance it was tuned to the same pop station, which didn’t have much variety. Now it annoys me if I hear any of the most-played songs on that station and songs that have similar sounds to them.
Lawn mowers and other types of yard machinery, even at a distance.
These are the ones that only annoy me, there is a much, much, much longer list of noises that cause sensory issues for me.
