It may not be that interesting hearing this in mono, I’m sorry for that one. It is a bit more interesting, when you realize that the buzzing, could be a light above me, sounds more like a hard drive, but I wasn’t around a computer, though it is in f sharp, electric buzzes 60 hz, b in US, normally. And the far off clanging, is, in fact, far off, somewhere across the room, it is a big lobby. I don’t think the two sounds were common, but, they do keep time.
