I would strongly recommend looking into the hunting regulations of your state to see whether hunting with a suppressor is legal. It's my understand that most states don't allow it.
If you're concerned about hearing protection, there are a variety of hearing protection devices that can be worn in the ear when hunting. A lot of them are even amplification devices that deaded when sounds reach a certain decibel level, such as the report of a gun. Walker's Game Ears come to mind right now, but I'm sure there are others.
