Although its none of my business...
Is your husband overweight? I used to snore when I was overweight. Now I only snore when I have a really bad cold..
Both of my parents gained a lot of weight and their quiet snuffling turned into house shaking snoring.
As I said earlier in this thread, my husband snores when he is sick or super tired....its horrible.
I get really grumpy if I haven't slept well....so if he is snoring I will usually go sleep on the couch or kick him out of bed....LOL!
