I just rewatched the Silencer Shop videos. One video they compare the the Nomad and Nomad Ti, they meter very close to each other.
Just pulling numbers from the videos looking at the Rem 700 .308 testing.
At the ear readings, these are two separate occasions so you need to take all the variables you can think of such as setup and weather.
No Can Ti/30 156.96
Nomad Ti 132.68
Nomad-30 131.41
No Can L 166.88
Nomad L 126.04
6 dB difference.
Now, seeing the great difference in bare muzzle I wanted to see their readings on the cans I own now, a Sandman S and Ti (I have a Nomad Ti in jail). So I watched their videos on those two.
No Can Ti 166.42
Sandman Ti 131.88
No Can S 166.8
Sandman S 136.8
5 dB difference.
Something is up with their Nomad-30/Ti bare muzzle numbers, they are 10 db lower than the other three occasions. Although I don't think it matters as comparing the at the ear numbers with the cans they are all very close. Does the Nomad L bring the dB below the magical 130dB safe threshold which I find bs because it still damages if you listen to it long enough, yep. But you should still be wearing something in/over your ears so with plugs/muffs at the range, does that 6 dB really matter? I don't think so, I can't tell enough to care when I have both my cans out with me with ear pro on. I bought my Nomad Ti to go on a hunting rifle, as it is way shorter and lighter than the Sandman Ti, and they meter the same.
So you need to decide, you want to lug around the L, or the Ti? I know what I want to lug around, and that is the Ti, which is why I bought it.
