That's like asking how bats catch bugs.
Ok, not exactly like that, as the Falmer don't emit a sound and listen for it to bounce off an enemy, but it's similar. Since their brains aren't distracted by having to interpret sensory information from their eyes, it can focus more processing power on their other senses, including hearing. Thus, they can determine with great accuracy the location of an enemy just by the sounds they're making. This is also why it's very easy to sneak around a Falmer lair with boots of Muffle. They're out of luck if you aren't making noise.
