While it is true that in the event of a high stress shooting you won't notice the report due to auditory exclusion, that doesn't mean your hearing won't be damaged. There are two basic solutions to this:
1- Get a suppressor for you home defense gun(s)
2- Have amplified hearing protection in the same spot as your HD gun, in the event you think it might be necessary, put on the hearing protection when you pick up the gun.
