The "aggro" zombies sometimes don't yell/scream after they see you and run after you. I've had this a couple times and the zombies run up behind me because I can't hear that they've noticed me. It might be because I am not facing or looking towards the zombies that causes this, even though I am close and in range of hearing them.

Happens only occasionally but I can confirm some zombies don't make a sound.
