Personal Moderator Testing Done

[roaoro]

After getting a new moderator, I decided to do my own testing to see which of my "larger" moderators were the quietest. Dry firing out of the same regulated gun at the exact same distance, and re-ran test 2 more times to verify the accuracy of the original readings. Surprisingly the retests showed the same results within .5 dB, so at least I know there's consistency in the readings.
Curious what order would you guys think would be quietest to loudest? My guess prior to testing was 4,3,2,5,1,6

6,5,1,4,2,3

What were you using to measure the sound? I've tried a cheap sound meter, an expensive sound meter, and a phone. NONE of these options provided consistent results.

PT6708. The first one I bought wasn't working right and was inconsistent. The 2nd one surprisingly gave me consistent readings once I figured out how to set it up correctly.

Depending on gun sound is different with and without pellet. Moderator performance also changes. Huben k1 quieter without pellet gk1 louder. Etc...

Why not test with a pellet? A projectile makes a difference in noise from the barrel. 1 mkre baffle in that IAmod would make it up to par with the rest

My guess -2-1-5-4-6-3. I only have experience with the Donny FL and ODB moderators out of your collection.

Ok, so makes sense with shooting with a pellet. I just wanted to do a quick test indoors since it has been 110° this week.
I went ahead and sweated it out today to test outside. Results did change slightly with shooting a pellet.
I decided to test my "shorties" while I was at it.
I tried to make sure the tests were all done as close to the same distance as possible. All test shots were done 15" at roughly a 45° angle to the sound meter.
Test gun was a Brocock .22 Commander shooting CPHP pellets shooting at around 885 FPS.
Here's my setup:

Here's the 3 shorties that I added to test:

My shortie guess prior to testing was: a,b,c.
