Sneak skill is determined, unlike other skills, in two means. Noise, and line of sight. Muffle, Muffled Movement, and Silence, all affect noise reduction. Being "harder to detect" or, sneak is % better, affects line of sight. I'm not yet sure if there is a cap on line of sight, but the obvious cap for noise, is 1 point of muffle. Acquired by: 1. Muffled movement + Muffle spell. 2. Muffled Movement + Muffle enchanted boots (self-enchanted only. Leveled loot muffled items, Assassins boots, Nightingale, etc., only muffle for .35 points. Also, only muffled boots from loots can be disenchated (for anyone who is unaware)) 3. Muffle Spell + Self-Enchanted Muffled Boots. 4. Silence.

It is currently unknown to me if the Light/Heavy armor perks to reduce all weight of armor, effects noise reduction. I would assume so, just not sure if it is for a full 1 point, but I doubt that.

Again, not sure exactly how enemy level scaling impacts your character's sneak ability, however I am positive that no matter the enemy's level, noise reduction is not affected, only line of sight. Of course, the difficulty and level of the enemy will have effect on their line of sight. I.e., a dragon has one of the highest sight detections at 90 sneak (most all revered dragons)

I'll do some more testing and hopefully bring light, and much more information to the perk description page for everyone
