Sound & distance

[Lunever]

According to the Sound, often monsters seem to be near, although there is no one around and the monsters are in an entirely different part of the dungeon, separated from the party by thick walls.
It'd be great, if at least walls and maybe even doors (partially) would muffle the sound created by monsters.
Best would be, if the sound volume of a monster would be calculated based upon the shortest distance to the party which is not occupied by walls and would then be muffled one "level" for every solid door in between.
