Am I imagining things? Sound attracts mob from far away right?

Mobs hear your trees falling and you hacking away at that copper ore. I'm pretty sure. They will track the sound

I have payed attention to try and see if it was a coincidence - but I'm pretty sure now. When you are making tree falls and hacking away with your pickaxe - greydwarves, trolls notice from far away and start heading your way.

There's always a first wave of attack soon after I start logging or mining then another few waves then I can mine in peace for a while - until I come back a day or two later and it's always the same pattern: the mobs that are close attack right away, then the ones that are on the outer edge of the noise range take a few moment more to arrive.

Does this match your experience? Am I imagining things?
