wacki, I work in a high-noise industrial environment* and have hearing good for someone my age that doesn't work in a similar field. This is non-typical among my peers, based on both their annual hearing test results and the fact that I'm the one who gets called to figure out "where that noise is coming from"** or "go out and tell us if the control relays are clicking when I do something, because Bob can't tell what the hell is wrong"***
So maybe my "feel" is based on many hours of experimentation with a variety of plugs in a variety of environments and with a variety of noise sources. And not based on reading advertising info from the boxes at the store or off the 'net, and not from shooting off a box of ammo once a year, but actually shooting regularly on top of work and on top of riding a motorcycle.
*(well, actually I've always worked in noisy industrial settings, now that I think of it ... how am I not deaf? What? Huh!?)
**(sometimes: "it is coming from you, Steve, that's tinnitus" ... sometimes: sounds like an air leak or a vacuum leak, go get a smoker to experiment)
***(sometimes the controlled component is dead, sometimes the motor/pneumatic/hydraulic actuator is dead, and sometimes it is just the control circuit)
