After two years of wearing plugs in a CNC shop with three turret pressing die punching up to 1/4" hot rolled plate, meh. It's like wearing glasses forever, you will get used to it. It's the first 30 hours of your life they are uncomfortable. It wears off, like wearing a wrist watch again or adopting flip flops after 20 years.
As for a silencer, sure, it works and can work well - but ONLY on the weapon it's mounted on. Not the OTHER weapons which don't have one and even worse, are pointed your way. That is why you might consider wearing ear protection in the middle of the night - in your flip flops, with a pistol in your hand, volume turned up a bit to hear the "wrong" noises you normally would not in the dead of night. Your pet moving around, you sleep thru, teens coming home at 2AM, not a threat (you will discuss it later) but a creak on a board which normally takes a human sized person in a room nobody is normally in at a night?
You can hear that from another floor with electronic muffs. Someone posted his experience hunting, in his stand he'd used for years, wearing muffs, he heard a repeated noise off in the distance. Turned out to be a windmill 1/4 mile away he'd never noticed before. Good muffs do that, while damping down ALL firearms reports.
Find me a silencer I can mount on my rifle which cuts the report of a gun fired at me, I'm in! Otherwise, I will do what the teams do, wear muffs - I just don't need the commz they share to go with it. They like to whisper, not shout and give location and tactics away to someone 20 feet from them.
