Clicking sound in apartment
I will describe this as best I can: I live in a high rise. At random times I hear a noise, seemingly coming from the wall or ceiling, like a loud click. The best way to describe it is to imagine if someone dropped a billiard ball on the floor above. It will repeat usually after 5-10 seconds. It can on for hours, on and off, or just for a short time. it seems to happen more in the afternoon and night than the morning. The people above have a young girl, but I can't imagine a rubber ball would sound so sharp. It almost sounds like a cane being tapped, but again very sporadically. I think it could be water or heating pipes, but have no idea. I don't want to speak to the people above because if it's not them I will feel stupid. So what the heck is it?
