Suppressors Compare the noise reduction of a TB 30PSS and 30P-1 when used on .223

I have a 30P-1 that I use on pretty much everything I own. Love it, love it, love it. I have a 30PSS in ATF jail, and I'm expecting it sometime in the next 3-48 months. The PSS is primarily intended for a .300 BLK SBR running subs, but it will also see use on a couple of AR's in .223.

I know what the 30P-1 sounds like on the AR's. I assume the PSS will be louder, but I have no idea by how much. Does anyone have any side by side experience with the two on AR's?

On full power .308 it's roughly 10 dB louder than the 30P-1

Not knowing anything about suppressor design, I was wondering if the numbers might be closer since the .223 uses so much less powder.
