I am on my third floor, and I can hear the metal and wood machines just like I am standing next to them.
PLEASE can we fix it so that you move away from it, it gets quieter...just like in real life. Yes this is very minor and not important, but its one of those little details that can make glitch seem a little more realistic.
Its especially silly when I start a machine and walk into the back yard, it should be peaceful and not really loud!
