The Talon P Moderator Design

[BlackICE]

I like it! Has anyone tried it yet, how well does it work?

My last post meandered a bit, so let me start with images of the directional reducing diffuser concept muffler. It does not have any features to protect the shooter from increased rearward blast (yet). The vents pointing back in the last row are at 45 degrees beyond pure radial. So, nasty for the shooter's ears in this concept design. The inside "tube" and front outside edges of those vents will reflect sound back at an even shallower angle, so any implementation of the idea is screaming for help to shield the shooter's ears - coming later.

Also, the ability to print the part standing on its front end will need to be restored via external supports. (Or a cylindrical design that has a swept hole pattern) Printing with the mounting thread down will collapse the internal cones; so that is not viable.

Anyway, consider this design purely as a goal statement, to spread the sound spherically, to make the sound less directional.

The vent holes are 2.5 mm in diameter as shown, but should print closer to 2 mm when FDM is used.

What about putting some veins on the shaft to reinforce it structurally? Would this be most effective on a pump action airgun?

To poster above, you should see the "microphone" above, without the vents

Having thought more about OldSpook's question about side vents, I decided that the above diffuser mufflers were not exactly what he meant. Also, they had some vents with a forward aspect to them. So, below is a muffler design that has only side vents added, with the front face punctured only by the central baffle bore.

There is a flange at the rear of the "head", to shield the shooter's ears from shock reflected from the inner surface of vents, and the outside edges of the holes. So, it should reduce the forward sound, and confuses the directionality by directing a lot of the total sound sideways - radially. Yet, without more rearward noise exposure to the shooter than absolutely necessary.

The STL for this design is attached as a ZIP file, below:

How about a modular combo design? Baffle and porous ran together? Baffles at the rear a porous up front?

Porous baffles, you could control the effect of the baffle with porosity.

Not sure what "it" you are referring to. In case you are asking about the side perforation mufflers, the designs were just created. As far as I know, no one has tried them.

Yes I was asking about the side perforation Muffler design. If the theory for speakers is the same for moderators then it should disperse the higher frequency sounds but be worthless for lower frequency sounds. That may mask the shot signature in front of the muscle.
