Today’s Topics:

1. Sound Signature Review 6.206 – Battle Born Supply Co. Whiskey Quebec 5.56 on the 14.5-in mid-length gas M4. The Purged version was evaluated in Report 6.207. This is the technical discussion accompanying those two analytical test reports, exploring the performance efficacy of Triply Periodic Minimal Surface (TPMS) baffle structures.

a. Intro and recap (00:06:56)

b. Basic TPMS geometry and applications to silencers, pros and cons (00:17:20)

c. Overall technical observations (00:29:25)

d. Conclusions (00:47:24)

2. Silencer Hazard Map Brief 8.1.5 – SilencerCo Saker 556 vs. the HUXWRX FLOW 556k on the MK18. Due to popular request to showcase a high backpressure conventional 5.56 silencer, we went back into the archives, all the way to Report 6.53 from 2021 and ran the test results through the PEW-SOFT HD Hazard Mapper. Does this Silencer Hazard Map for the Saker 556 help illustrate operator risk when using these types of legacy silencer designs? Can a HUXWRX FLOW 556k save you? Maybe not. (00:50:17)

1. Sound Signature Review 6.206 – Battle Born Supply Co. Whiskey Quebec 5.56 on the 14.5-in mid-length gas M4. Inconel. 3D printed. Are there folks out here using 3D printing for things that are simply not machinable by traditional methods? Yes. This family of silencers is one of them. Let’s explore the performance of Triply Periodic Minimal Surface (TPMS) baffle structures in the intro to this report published with today’s episode. (00:08:06)

2. Sound Signature Review 6.207 – Battle Born Supply Co. Whiskey Quebec 5.56 Purged on the 14.5-in mid-length gas M4. This is the high(er) flow rate brother to the silencer we just discussed. Both silencers have high early-time flow rate. What if you increase the late time flow rate? Let’s check out the performance differentials in the intro to the second report published today. (00:27:16)

3. Silencer Hazard Map Brief 8.1.4 – Analytical test reports too long for you? Maybe you don’t have time to dig into them yet before you eat turkey and pumpkin pie? Not a problem. Hit this Brief for a succinct look at how the Whiskey Quebec 5.56 (Purged and non-Purged models) project hazards to personnel, spatially. Pictures are good! (00:34:15)

1. Sound Signature Review 6.205 – Combat Application Technologies CAT BEN micro silencer on the subcompact Beretta 21A. Rimfire is back. Compact? Yes. Everyone wants to put small silencers on subcompact hosts. Sometimes that can be pretty loud. Does the BEN offer relief? Technical discussion for this report and PEW-SOFT HD Hazard Map published last week.

a. Introduction (00:06:42)

b. Silencer Hazard Map Brief 8.1.2 (00:14:36)

c. Technical performance (00:19:10)

d. Final thoughts (00:41:18)

2. Silencer Hazard Map Brief 8.1.3 – Unsuppressed MK18 in the free field. There has been a lot of talk about blast overpressure, human risk, and traumatic brain injury (TBI). This deliverable should help folks get more familiar with blast loads, understand blast overpressure in familiar terms, and help silencer folks become more familiar with traditional blast overpressure hazard and human risk vernacular.

Today’s Topics:

1. Today we are launching Section 8 of the Silencer Sound Standard: SSS.8 – Advanced Silencer Research. Outside of public view, PEW Science performs a significant amount of testing and engineering analysis on a variety of systems; most of which is never published. Not everything has to remain behind closed doors. Section 8 of the Standard presents further research advancements that are cleared for public release. (00:04:02)

2. The first section in Section 8 is live today with this episode! The first report in this section is SSS.8.1.1 - Introducing PEW-SOFT HD Hazard Maps. The Suppression Rating has made you powerful. Now, you will become even more powerful, as you navigate personnel hazards from silencers in both the free field and near reflecting surfaces; everywhere. We’ll walk you through the report in today’s talk. Here is an outline:

a. Introduction (00:08:22)

b. 8.1.1.1 - Dimensional Variations (00:20:12)

c. 8.1.1.2 - Free Field Data, and You (00:22:55)

d. 8.1.1.3 - PEW-SOFT HD Hazard Mapper (00:31:19)
