I think that's a fairly intense, but natural response to what happened with your house. Auditory hallucinations are actually surprisingly common in mentally healthy people, things like hearing your name, hearing your cellphone ring, or hearing music when there's none there. For you, I could see hearing water dripping being one of those benign hallucinations (and they are particularly common when there's a lot of white noise around, like the fridge running or the fan). Oliver Sacks has a nice book called Hallucinations which covers those phenomena, among others, if you're interested.
Have you considered taking them to court to pay for your repair costs? A nice letter from a lawyer might be enough to make them decide to fix it.
As for the panic/rage, you might want to look into a short course of cognitive behavioral therapy to help you deal with the feelings and how you react to them.
I think sounds can upset but it's more learning to deal with ruminating. You know over & over in your mind.
This will sound very simplistic, but why not move to a different place?
