I find it a bit odd that you can hear cows and chickens from a long ways off even if you cannot see them. Is there some way we can add a new type of block into the game that would muffle sounds - or at least reduce them forcing several layers to sound proof an area ? Make it something alchemists or smiths can make to limit them. People who want to build a livestock pen underground in a non-regioned area can surround their pens with this so people walking by don't hear them. Heck make the block transparent if you want so it only muffles sound but doesn't block line of sight.
