I think I posted this somewhere about a month or so back but I can't
find it. So let's see if I can rework it.

I can't find it either so, YES - please do rework it for us.

Us?

You want to know how sound travels?

Ok then but only because it will upset Skywise to find anyone other
than him reading my trash.

The roaring noises of a distant river or road that can on some days be
heard more clearly than on others, tells us that some sort of
inversion channel is in place. The same sort of weather betrays
aircraft noise patterns and other strong noises whatever their source.

We know that it must be being channeled. And we think we understand
how inversions bend and flex the sound waves involved.

The question left then is: Does it work up higher in the atmosphere?

And the make or break one:

We know from the way seismographs behave that the earth carries a huge
amount of noise from wherever to wherever. But do the sounds originate
in the earth as some would have us believe?

I happen to find plate tectonics a ridiculous idea. So my mind is
already made up. That doesn't mean I haven't got to provide an
alternative source if the meanderings of lumps of rock the size of
continents isn't going to do it.

So do cyclones provide enough vibration to set up a sort of sympathy
deeper in the planet?

When you think how much noise a couple of turbines can do in lifting a
few hundred tons of aluminium, it stands to reason the reaction to
shifting billions of tons of air just as far and just as fast is going
to accomplish similar sorts of things on a much grander scale.
Paraffin powered turbines are no more than glorified air compressors
after all.

I wonder if there is some place that has taken measurements of these
things.

That's as far as I kept track. I think I got a spell check organised
by the next installment and stopped using OOo.

I received a couple of news letters from the owner of Skywarn Forums
telling me about some of the latest upgrades, so I wrote back
explaining in scholarly tones that he was some sort of a fool for
banning me then inviting me to view his handiwork.

So he wrote back that I wasn't banned, so I went to have a look see if
I could find anything on there that concerns this thread. As I had
cleared the cache a time or two since going there I had no trouble
getting in. But that all changed when I tried to sign in.

Maybe he is having trouble with his servers. But it is on
Sourceforge... there again the weather would make his site pretty
busy. There again, I live 1/3 of a world away and wouldn't be
penalised for hitting it in the middle of the night. None the less I
couldn't get in.

So stuff the place. I will write it all again from scratch.

Or not, as the case may be.
