Sounds weird. I know. But let me explain. In an episode in season 5 (I forgot which), we see spongebob's alarm go off, and his bed gets blasted to the other side of the room. As I was watching this, I was thinking, "could that actually happen?", so that's what we're going to find out. A study in July of 2013 shows that a toothpick can be levitated via sounds with 160 decibels, and an average toothpick weighs 100 mg. For sake of simplicity, let's say that spongebob's bed weighs 100 lbs even. 100 lbs into mg is about 39,510 mg. Now we multiply 39,510 by 160 to get 6,321,662 decibels to move spongbob's bed (assuming if he's not in it.) A typical jet engine is around 140 decibels. So it's safe to say that this thing is loud. How loud? Well, a human eardrum typically ruptures at around 150 decibels. Meaning that your eardrums would rupture 42,144 times over. But that's not all. A study in October, 2015, shows that it would take approximately 1,100 decibels to create a black hole larger than the galaxy. Well, we have a lot more than 1,100 decibels. In fact we have to make 5,747 black holes the size of our galaxy every time spongebob woke up. Talk about a heavy sleeper.

Edit: I'm seeing the comments; this was assuming that spongebob's bed was regular size, and it wasn't underwater. Sorry for the confusion!
