I own a few but not an expert on suppressors or how the values are measured. Most makers list “at the muzzle” numbers. Is this the same as what you’re calling “at the shooters ear”? If so, then 140 isn’t terrible comparatively. A cheap Silencerco Harvester, that I own, takes a .308 down to 135db. Honestly I’ve never noticed the weight one bit. POI change with and without it mounted is my biggest gripe.
Shooter ears is 1.6 meters off the ground with the mic 6 inches from the shooters ear on the right side.
You Harvester, assuming a newer EVO is pretty light at 11 ozs without the mount which add another 2 ozs. It adds 6 inches of lenght to the rifle.
My 4/2 Ti is 4 ozs mounted and adds 3.5 inches to the gun.
Lots of tradeoffs but I set out to capture the smallest lightest market, not the most quiet.

I have all the sources. They can't stop the signal.
