Yeah, absolutely! I hear it whenever the space I'm in is relatively quiet. I also hear it a lot while wearing earbuds and listening to something, especially while walking. I presume it will be quite loud when I get back to running, but perhaps it'll be covered up by the sounds of my suffering.
As for the annoying: nah. It never bothered me, although I've been told that some people find it hard to get used to. Apparently, I made a groan of realisation in ICU post-surgery when my partner described the high pitch metallic clock/watch ticking noise to my parents to help them identify it. My partner pretends to be annoyed by it, but she doesn't _really_ mind.
