Yes, I cant help you on hearing loss or noise.....You gotta go with a suppressor for that and or good ear muffs.There's more to the equation that just recoil reduction.
I did ask and think about a change in barrel harmonics before I bought mine though, because I am also interested in accuracy.
What I planned and am working up is an integrated barrel tuner with brake. I think for smaller calibers say less than .30 you can probably go with the Eric Cortina tuner brake and be ok. For larger magnum rifles though recoil reduction has to be a big part of the answer?
Why? Because barrel harmonics and torsion are going to be worse in big magnums. So is human flinch.....So my approach has been get the best brake with most recoil reduction you can, combine it with a barrel tuner and you will have a more flinch free, small group experience.... But you do have to wear ear protection or just go to suppressor.
It is my belief that if you trade off noise for amount of recoil reduction, you are implicitly trading off accuracy too.
Lots of recoil but quiet muzzle blast is not going to result in small groups. Just my opinion.
Get the most recoil reduction you can if you can use earmuffs for noise control.....
I sure admit I dont like shooting benchrest next to a big .50 with muzzle brake, even with ear muffs.
Those rifles shake the whole shooting line.
