Having Naruto in any clan would heavily shift the balance of power in said clan's favor and I can easily imagine someone like Hiashi throwing a fit about it.
Especially if Hinata still has that massive crush on Naruto in MfD. :rofl:

"Yes daughter, you are permitted to marry the village destroying superweapon that will bring our clan unlimited power and propel me into becoming Hokage I mean, your crush who I in no way have plans to manipulate." :whistle:
 
Hazō: I got an idea!
Jiraiya: *groans* Let's hear it.

"Wow, nobody's made that face since Kagome caught me trying to inscribe a storage seal onto a Mobius strip.

-or when those Mountain-nin heard me suggest that we all mix our blood together and sign the summoning scroll simultaneously.

-or when I suggested that Pandaa learn genjutsu so he could snipe people's brains into stone..."

Insert that "NaruHina = Hiashi's Keikaku " thing.

FUCK THATS ACTUALLY A CONCERN HOLY SHIT

You have likely seen this but if not:

Pandaa: Why does everyone fall asleep and get all stiff when I sing in that special opera voice Mari taught me?

Hazo (removing Banshee Slayers): Huh? Oh right - your voice is just really soothing, and they are definitely sleeping. Everyone loves your rendition of "Kurohige and the Nine Knaves."

OTOH: Pandaa is totes comfortable with Condor Genocide.
 
This is going to grow quite a lot as I get more of these written up. Thought I'd post the first few drafts to see what people think, where I can add more specificity or if there is a common portion that people think is missing
Quick comments because I'm likely to forget if I don't do it now. This isn't specifically aimed at you, I just think these are important questions.

Blows up on destruction: Yes. Inconsequential.
BWAHAHAHA! Good one!
Effect: Emit a 20 kHz tone at 190 dB
Oh, it was 20kHz? We should bump this to 25 kHz so we can break ears without them being able to notice the sound. Try for our own version at the very least.

"Emit a tone at 190 dB" isn't really a well-defined thing, and more than "emit a heat at 300°C" is a well-defined thing. A 190 dB point source has no volume at any positive distance, just like a 300°C point source has no heat. Sound is emitted from surfaces of a given area, and the volume drops off as the surface area grows, as long as it can be approximated as sphere-shaped, and you aren't going too far out.

If you emit sound from a 1m radius spherical shell, it's going to be 40 dB louder (10000x SPL) than if it was emitted from a 1cm radius shell at any distance ≥1m. You need to define a loudness at a given distance, and only then can you derive the size of the source using basic math.

A mere 1cm radius shell would only sound like a 150 dB Earbuster at 1m distance, but whereas the 150 dB Earbuster (assuming similar 1cm radius source) will drop off to 130 dB the next meter in, the second meter would only reduce Jiraiya's from 150 dB to 144 dB.

This size pretty much matches your mechanics in dropoff, but it means the peak decibels are hard to hear unless you put it next to your ear or something stupid like that. But I'd expect a source large enough for those sorts of effects at close range are much louder than you gave at medium range. Note that sound attenuation at long distances varies a lot by frequency; a 20 kHz sound probably won't ever go further than 200m, but a 200 Hz sound could go 50km!

Secondly, that leaves a bunch of specific questions. Where is the emission from? Is it just from the surface of a sphere? Or the surface of the tag? Or the whole volume of a sphere? Is the sound a pure sine wave?─this affects whether it stacks. And if you overlap the producing volumes, does that stack, or is it like EM where it refuses to?


Personal suggestion: It emits from the whole volume of the sphere (because that makes the math easy), in an imperfect sine wave (because that reduces the need to care about interference effects), and stacks additively (because that's most intuitive).

Opponent Rolls an Athletics against the Infuser's Sealing to dodge (behind an obstacle) and take half-damage.
This seems like an odd choice. It travels at the speed of sound, and you'd need to know what it does ahead of time to make the right kind of dodge. Assuming the team is wearing protection, a basic technique is to trigger it while holding it, which should basically be undodgeable. I don't get where the infuser's sealing comes into the picture.
At creation time you choose a level of sound-dampening. When activated the seal dampens air vibration within ~2cm of itself. It is useful against loud noises and sound-based (nin/gen)jutsu.
Is the attenuation permanent? As in, is the sound restored when it leaves the area under effect?

I had a whole run of posts on this, but you're right that I forgot some of the specifics in the write up.

It is a uniform vibration within a 1 m sphere (which I chose to make the math work), and an emanating wave beyond that sphere's surface. I chose 20 kHz specifically because it was audible and it made the wave dissipate quickly enough not to warn everything within 10-100 km. My model is

# Engineering Acoustics/Outdoor Sound Propagation - Wikibooks, open books for an open world
import numpy as np
## Settings ##
R0 = 1 #m - the initial radius of uniform seal emanation
dB0 = 155 # the uniform sound intensity within R0
groundReflect = 1 # either 0 or 1, 1 to use ground reflections
targetdB = 140 # the target threshold
## Model ##
Rn = R0
dBn = dB0
while dBn > targetdB:
Rn = 2*Rn
#dBn = dB0 + 3*groundReflect + 20*np.log10(R0 / Rn) + .001*(R0 - Rn) # 200 Hz
dBn = dB0 + 3*groundReflect + 20*np.log10(R0 / Rn) + .7*(R0 - Rn) # 20000 Hz
#dBn = dB0 + 3*groundReflect + 20*np.log10(R0 / Rn) + 8*(R0 - Rn) # 200000 H

Rlo = Rn/2
Rhi = Rn
while abs(dBn - targetdB) > 1e-6:
if dBn < targetdB:
Rhi = Rn
else:
Rlo = Rn
Rn = (Rlo+Rhi)/2
#dBn = dB0 + 3*groundReflect + 20*np.log10(R0 / Rn) + .001*(R0 - Rn) # 200 Hz
dBn = dB0 + 3*groundReflect + 20*np.log10(R0 / Rn) + .7*(R0 - Rn) # 20000 Hz
#dBn = dB0 + 3*groundReflect + 20*np.log10(R0 / Rn) + 8*(R0 - Rn) # 200000 H
print('The wave attenuates to {} dB at {} meters from the seal'.format(dBn, Rn))

Local zones are the first 5 m. For every additional 10 m or so, an additional radial zone. 175 dB for death threshold (5 m in this case) 160 dB for big pain (15 m) 150 dB for small pain (25 m) 80 dB for Warn (105 m)

Will add the sphere/size thing, because that is important for other people interested in modeling.

***

My impression is that the banshee slayer completely attenuates soundwaves above the dB threshold that enter the effect. Sound may propagate around the effect and be heard on the other side, but if the seal was on e.g. a hole in a wall, sound would not pass through the hole (but may transmit through wall)

Edit:
As to the dodge thing - exactly the same reason why folks get to dodge the goo bomb. Would it seem better to you that, if tied to a weapon's roll, the weapon's dodge counts toward dodging the sound seal? Only, I'd figure that most people wouldn't dodge behind an obstacle for most weapons attacks.

Edit the Second: As a force emitting seal (like many demonstrated attack seals) I felt it appropriate that Wind Gust seal would blow up. As a training seal from the Nara list, I also felt it appropriate that it be a minor thing. Maybe I can write like 1-stress or something.

Edit the third: Attenuation also varies fairly substantially with humidity (in the link in the model) - I effectively took a value from somewhere in the middle of the range at a given frequency, so maybe generally around 50% humidity. As a general rule, I think this is probably ok. Might revisit if we ever spend a ton of time in Sand and QMs want to bring it in as a quirk of the area.

We tried to make some sort of "LBFS + Seals in a tube" device earlier so that we would have easily activated seals (by civilians I think).

The main issue was: Hazou couldn't quite figure out how to get the seals aligned correctly since he couldn't see them (they were in the tube).

Whats to stop:

1) Us doing this in pieces of a big wooden tube thing and then gluing the halves together.
(presumably in such a way that you can twist the device or something and the LBFs become unaligned, and so the seals activate)
2) Using this to make grenades?

The GMs, of course.
