I'm like that but it's with ticking watches or clocks. I cannot stand it. If there is a ticking clock in a room, I will focus on that, no matter how hard I try to avoid hearing it.
I must have all bank notes in the correct domination and also facing the same way. It drives people mad when I decide I'll change them all to facing the correct way! When I'm folding several things, they must have the open edge at the same side. Ice cube trays, I hate them being half full/empty, so I will make some more so it's full. When you see someone at home and they go out the room and leave the lights, every time! If they switch it on, they can surely switch it off! I'm sure there are more which I will add as I think of them.
Should I add Sir David Jason, or are we all aware of my obsession?
