Re: SM and stealth
Why would SM affect hearing? Ground pressure and wing loading are the main things that affect the noise made by ground creatures and avians. These aren't really proportional to SM in a useful way, and depend more on specific species morphology than on absolute size. I'd agree that SM may matter for vertols, but that's why you can take "Noisy" as a Temporary Disadvantage on Flight.

Re: SM and stealth
Um. 10 psi over 1 square inches makes less noise than 10 psi over 10 square inches, and (ground pressure*area) most certainly scales with overall body mass. For flight, noise will tend to scale with motive system power, which also scales pretty strongly with body weight.

Re: SM and stealth
That's what I'm disputing. I've seen nothing to support that claim. My understanding is that ground pressure alone matters. 10 psi is 10 psi is 10 psi . . . there's no difference in noise between a 0.1, 1, and 10 square inch sample. This is certainly how the U.S. Army handles the matter in their assessments, anyway.

Re: SM and stealth
That's only true under certain circumstances. Travelling through foliage a giant would make more noise because it has to force more stuff aside. Running, the impact of the footfalls of a heavier person is louder. Broader feet can break more branches and dry leaves. But on solid ground, or clear soil and moving slowly and with deliberation there's no reason why a big guy will make more noise than a little guy. Although the big guy is less likely to be trying to sneak in the first place, if his size modifier is such that he'll be toast on the vision modifier anyway.

Re: SM and stealth
Because SM and weight are not connected, That huge Gassious form weighs almost nothing... (low weight big SM)
