    Just out of curiosity, today I mounted the following moderators on my Bantam Sniper .22. Sound level readings were taken several times with similar results each time.  I used an app on my iPhone to measure the peak sound level, at 9' ahead and off 45 degrees to the side of the muzzle, with the microphone pointed toward the muzzle of the Sniper.

    The Bantam Sniper .22 WITH shroud, but WITHOUT moderator measured 108 db.

    Before the testing, I had a feeling that the Huggett was giving me the best sound moderation, and according to the SPL meter, what my ears were telling me was correct.

      Size Volume Weight SPL @ 9'
    Huggett Snipe 1.22 x 6.73" 7.9 ci 4.6 oz 89 db
    Shogun 1.6 x 8" 16.1 ci 7.2 oz 91 db
    Tatsu 1.6 x 4.25" 8.6 ci 4.1 oz 94 db

     

    Note that these are not dramatically different sound levels to the ear, but they are audible, in particular when going from the Huggett to the Tatsu.

    What is interesting is that the Hugget has the least internal volume of the three moderators, yet gave the greatest sound moderation!

    The most noticeable difference that one can see externally (other than size/shape differences), is that the Huggett has vents near the muzzle end of the moderator and the DonnyFL's do not.  Perhaps those vents have a significant effect on moderating the sound level, more significant than internal volume of the devices?

    Taking in comparison inch-for-inch in size, and cubic inch-for-cubic inch of internal volume, the Huggett turns in a very impressive performance!  As it should, I suppose, given that it is priced a fair bit higher than the other two.  

    Considering that the Tatsu is about 65% of the price of the Huggett, it does a pretty good job of moderating, but a 5 db difference is audible.

    As I am trying to keep the sound of my pellet rifle shooting as low as possible (I shoot daily and have some neighbors not terribly far away), I know which moderator I will be using most of the time.

    That is interesting. One thing to keep in mind, is that different moderators dampen sounds at different frequency/pitch depending on their design and materials. Our ears interpret these sounds at the same output (dB) as either louder or not. I know with some powder burners, I have been fooled by the decrease in perceived loudness from can to can based on that theory. 

    I guess you'll be getting your money's worth with the Hugett!

    Here's to happy and stealthy shooting

    Yes… I know that to the ear, a lower frequency report can seem "quieter" than a higher frequency report of the same measured db level.

    That's why I wanted to see what a SPL meter measurement, in db, was for the moderators.

    I agree, if the price is not prohibitive, and you want maximum moderation without needing a large moderator size, the Huggett is a great choice!

    On the other hand, if saving a good chunk of change is desired, the additional effectiveness of the Huggett, as compared with the DonnyFL options, is not dramatic.

    Where did you get the volume numbers from?

    Calculator.

    Please, tell us how YOU would get the volume numbers?

    You must be in the business of selling calculators.

    OK Mister SmartyPants!  Tell us all about YOUR special calculator.  Does it use your "new math"? 😁

    OK Mister SmartyPants!  Perhaps you should enlighten us as to what you think the volumes actually are?  With your "new math"? 😁

    I guess you are unaware of how to calculate the volume of a cylinder?  Let me know if you need help with that.  😉

    Maybe he's using the common core style of math. My son always tells me "Dad your doing it wrong, that's not how the teacher taught us"

    Haha!  Yeah…. common core. 😝  A cylinder's volume is a cylinder's volume, no matter what math-style you use.

    18.13 is acting like a smarmy "know it all", and he's wrong.

    I really would have liked to see a Weirauch moderator in that test, I think people would be surprised how quiet and efficient they are.

    I would too.  Been thinking about adding an HW110 at some point – though not sure that the mod on that would fit on my Sniper – for comparison purposes.

    I've heard that the Weihrauch is a very effective moderator.  And I know for sure that the Huggett is great!

    Hey Dhart,

    I know the donnyfl has felt, aluminum screen, & baffles. What does the hugget internals contain? Maybe the material he uses is what's making it quieter.

    I don't know how the internals differ, though I'm sure that they must differ to some degree.  

    And, there are those vents on the rifle end of the Huggett that are a very obvious difference. I would think that those vents must make a significant difference, otherwise, why would Andrew have bothered to do that extra work?  

    That the Huggett is about 2 db quieter, while having only about 1/2 of the internal volume of a Shogun, is amazing.

    I will have to tear into them and see what differences I can find internally.

    No I think he can calculate cylinder volume in his head so just the fact that you use a calc enraged him.

    @dhart. I think the new DonnyFL mods have the front like the Huggetts do.  How old is yours?

    Haha!  Funny!  

    His commentary was both rude and wrong.  Short pier candidate as far as I'm concerned.

    My Tatsu was shipped by DonnyFL about two or three weeks ago.

    i have a Weirauch moderator on my Weirauch and the only thing you hear is the click of the hammer. It’s only a 177 cal so I can’t speak of noise level on 22 cal and 25cal.

    Well if I'm doing this right my calculator shows

    1.22 X 6.73 = 8.21

    1.6 X 8 = 12.8

    1.6 X 4.25 = 6.8

    No Pi symbol plus hard to write the equation here but need to take the area of the cylinder and multiply by the length.  So his volume numbers are correct since the first number is the diameter of the moderator and the second number is the length (V =  π r2 h).

    If I'm wrong I'm wrong and sorry I didn't mean to be rude.
