I have no experience with them. I could see where someone might want one, though.
I suppose the intrepid home guardian could keep handy with his guns some sort of noise protector plugs or earmuffs (aren’t there some which allow near normal hearing yet filter out sharp bursts as from guns?). They take what, 5 seconds to pop in or slip on?
And/or, cover your ceiling and walls with noise absorbent material. If kids scream and holler, which most kids do from time to time, it’s nice to avoid propagating the noise through the house more than necessary.
If you can get the silencers more power to ya of course. But unfortunately our Caesars have sometimes made it more trouble than it’s worth.
Another, cheaper alternative is active electronic hearing protection. Good muffs that amplify sound and shut off in a micro second for very loud noises, such as gun shots.
I have used them a lot, and they are pretty effective.
