If it is a "physical" failure, it'll likely be the bearings that give out - and most times, most bearings will start making a groaning or humming type sound.
If the failure is electrical in nature, it is common for there to be no sounds or symptoms like that to give you fair warning.
Low voltage resulting is things like starting problems, battery not charging, dimming lights, will be common symptoms of a failed alternator.
