I am weighing out the idea of a suppressor vs. having hearing protection hanging next to the bed that could both protect and even enhance my hearing.
I'd go with the hearing protection for several reasons. Electronic muffs not only protect your hearing, they can make it better. Electronic muffs are much cheaper than a suppressor and they work on whatever gun might be discharged, including one the attacker may have. Ear muffs also don't have the stigma attached to them in the general population that a suppressor might.
