I think, when it comes to 5.56 out of semi-autos, the expectation should be either not hearing safe or very close to 140 db at the ear. Is there a way to measure tone in a way that can be translated into a comparison between cans? I suspect this would be hard because we all hear a little bit differently.
“Pew Science” claims that they have a new standard for comparable independent testing that takes variables beyond peak db into account. Could be something to watch, or maybe it will be a flop. Dunno.
