With an effective suppressor, those can be reached in pretty much all sporting & hunting centrefire calibres.

Whereas with a good and effective muzzle brake, the unsuppressed levels at the shooters ear can be 5-10 dB louder.

So the levels that the shooter will be exposed to are c. 163-170+ dB if not using any hearing protection.

Ase Utra sound suppressors

Hearing safe is a very subjective subject, I'm not an expert but suppressed rifles still make my ears ring so damage is being done, not hearing "safe" for me.

I shot isn't too bad but multiple shots not so much, hearing damage is cumulative

Yes much better than no suppressor & miles better than any muzzle brake.

I have a couple of your suppressors I quite like them reasonably compact & lightish
