[LOTR] How do the orcs in Moria know that a random noise come from adventurers and not from normal stuff you can find in an abandoned mine?

Do they get worked up everytime there is a noise? What activity are they doing while waiting? Tens of thousands of orcs and a few cave troll must make noise from time to time right?

They didn’t know, as such, and yes, they do react like that to any unfamiliar noise.

Do you have any idea how boring it was, hanging out in Moria? Nobody to fight, nothing to eat, no one to steal from - except each other. It’s been decades since Balin’s group dropped by, and since then it’s been nothing but friendly knife fights in the dark and a steady diet of lava-roast goblin.

Even the faintest possibility of entertainment is worth climbing up from the fell deep for.
