Tactical Sound Detection Rules

[pmulcahy11b]

One of the US-based National Labs was experimenting in the early 2000s with a sound horn that can develop 260-280 dB. It's directional, can be tuned to a narrow beam, and can bore holes in reinforced concrete up to a foot. (Don't get in front of it!) It's not dangerous outside of its beam.

(I found that in an old Guinness Book of World Records. There's probably much better technology now.) I'll have to look that up and find out more about that. Be back later...have to let my dogs out soon.

Be something like interesting in a Merc 2000 campaign that a bad guy has captured and the team is to sent to destroy.

Didn't find anything on that yet, but I found this, which may be interesting:

Mods, someone needs to teach me how to turn a URL into a few pertinent words instead of quoting the whole URL in the post. I don't know how you do it. Could someone get with me in PM or email and give me a tutorial?

How do you model noise discipline precautions like digging generator pits or conducting short count starts in assembly areas?

Put a "deduction of Decibels" in place to model it. A ditch might provide 10 Dbl of reduction while a woodline COULD give you as much as 30 Dbl. NOTE: 5 Dbl is a typical sound reduction (essentially "halving" the sound) and 30 or more is a SEVERE REDUCTION in sound (most hearing protection is only 20 to 25 Dbl in reduction). Even camo netting will absorb some sound (about 5 Dbl).

Thanks. Although I’ll confess that anecdotally generator pits seem to be infrequently dug in practice. More use of terrain and woodline seems to be the reality.

It does seem that a single generator running in the woods supposedly something like a beacon for reconnaissance units looking for TOCs and Field Trains.
