10: Matmos Sound Mod
Big and old and still updated, this mod takes care of Minecraft being quiet. Too quiet. It adds environmental sounds in relation to the players’ current environment, and gets rid of the perpetual silence that has haunted Minecraft forever, for whatever reason, and creates a much, much more immersive experience.
Usually I am not a fan of these polishing or high def mods, but when it comes to sound alone, Minecraft is a bit lacking. Sure, the zombies and creepers are iconic, but there is just very little else going on. This environmental sound simulation changes that, and oh boy does it ever make a difference. Give your ears something to mine on right here!
