# How fast is an acoustic wave on a fat woman's buttocks during doggy-style sex?

Thought of it while disinterestedly watching porn on the Net. (That sentence is a good one for for any number of reasons…) Besides intrinsic interest, it would be good for a nerd “your Mama’s so fat…” joke.

::Off to find a strap-on dynamometer.::

I don’t know the direct answer, but I’ve seen high-speed videos on YouTube of all sorts of things, including acoustic waves on a woman’s buttocks. It wasn’t during sex, but the cause is probably irrelevant. You could make calculations based on what you see.

To save you the trouble of clicking this link I have cut & pasted the equations below.

The same speed as on a skinny woman, just does not have as far to travel

I thought the speed (and height) of waves depended on how deep the water - I assume the same applies to bodies - the speed and visibility of waves on a female anatomy are proportional to the depth of the fat layer through which they propagate.

I doubt that the OP is actually asking about acoustic waves. Acoustic waves in a mostly-water medium would travel at thousands of miles per hour, and would not be visible in anything but an extreme high-speed video. Probably what the OP is actually wondering about is the transverse waves which can be seen rippling across the surface.

They’re moving at the speed of love.

And so, boys and girls, we can see that engineers are not like you and me.

while having sex there is no application of the ideal gas law.

Damn I love the dope.

I have removed the copied and pasted text from Lukeinva’s post (post #3) as it copied most of an entire wikipedia article. That goes a bit beyond fair use. The link to the article is still in Lukeinva’s post.

I agree with Chronos. The OP probably wants the speed of a Rayleigh wave which is somewhat complicated. It’s significantly less fast than a pressure wave though. Probably less than 10% of it.

You know, it is not really necessary to do all these calculations - most people just think about baseball to keep going.

For pigs, this velocity is about 3 m/s.1-Hz surface waves in the skin propagate primarily as Rayleigh waves with a wavelength and velocity of approximately 3 m and 3.0 m/s, respectively

You can do similar calculations for human skin - the data is all here. Damn, if I do these calcs.

Or you can undertake research (funded by NIH of course), recruit Volunteers!! and publish the results. Oh - and “Double Blind” studies are mandatory in this case.

So, you keep doing that, and then you keep doing it again?

Raleigh wave or seismic wave? He did specify “fat”…
It wouldn’t be a soliton in this case.

So?

Back on topic:

How about a comparison to Dark matter sound waves? That would be pretty damn nerdy…

Somebody’s gotta find a video of a girl with a two big ass zits and measure the time between their respective bounces as the wave passes.

I tried to find one but got distracted, now I’m not really interested and kind of need a nap, but I can try again in a couple hours.

Considering that it does not even have a subject, no it isn’t.</Grammar Nazi>
