Wake up, Arny! You're not talking to them, you're
talking to us.

And your whining proves that you exactly understood what I said, but are on
yet another one of your pedantic binges.

Binge on, dude! ;-)

I don't understand a word of that. YOU'RE ignoring the accepted
definitions of certain terms. "Backed up"? Eh?



You ain't my daddies, Laurence, Kitty, Iain.
Oh yes I am! :-)

Interesting to discuss whether "hear" is the right term. Do we "see"
infra-red?

That's probably why Jim put it in quotes.

No, nor can we sense it with our eyes. If you sense IR at all it is only
because of the warming effect it has on the skin. OTOH you can be aware of
air-borne infra-bass because the air-movements are detected by the eardrum.
Certainly the sensation is quite different from normal hearing, but then we
don't know what it "sounds" like to a pigeon either :-)

I guess that's why the Lord Mayor of Hiroshima said "What the f**k was that".

Tis here, it's a really interesting page.[I thought, maybe I'm easily entertained].

Above said, it isn't clear to me what relevance it would have for something
like recordings or broadcasts of music/speech.

Non whatsoever, that I can think of...but there are more things under heaven and
earth etc..

Not quite correct. I can certainly 'sense' infrared with my 'eyes'. But the
sensation of dryness and soreness of the front of my eyes. I think it may
be due to evaporation when my eyes are exposed to significant heat sources.
e.g. when making toast in the morning even though the flames of the grill
aren't directly visible.

And, in my experience on the eyes.

Indeed. Mind you, I don't know what music "sounds like" to *you*, either!

That's an exact quote - you're sure about it?

A little research suggests that there may not have even been such a person
in 1945. That he exists now is questionable evidence since the city and
country were so profoundly reorgainzed after WW2 and back-to-back near-total
destruction by both The Bomb and a massive hurricane.

I was thinking that not-infrequent generators of strong subsonic waves
could include improperly designed or operated petroleum processing plants...

I suspect he didn't get to the end of the sentence!

However any 'bang' near the explosion would have been a blast wave, so
contained a wide range of frequencies, not just ULF. That said, such waves
do tend to be dispersive so tend to be more like LF at large distances.

I can recall having some pressure sensors at my old Uni (QMC as was) that
used to show a gentle variation in air pressure a few times per day. Was
eventually identified as the remains of the shockwave of Concorde flying
across the Atlantic. Much quieter than the noise it made over the NPL,
though. :-)

And that was much quieter than standing near to 001 as she wound up at
Tolouse. 8-] That and some tests with a tank (Challenger II IIRC) were
the loudest noise sources I've ever risked my own ears on.

Let's put it this way, for me the NT4 is a tool of

Well, at least you're doing SOME paying work :-)

I'd love to hear some short examples.
I've said what I'm going to say about that until there's
real change around here.
I don't think there will be, until you display some
results to back up all your opinions.

The ability of certain members of this forum to ignore reliable references

Do we have to provide DNA samples to have that officialised...??

Appropriate language gets your meaning across in both cases.

It's been too easy for Arny - pulling the wool over the
eyes of the goodly Baptist bretheren for a very long
time. He preys upon their lack of knowledge and
experience

It doesn't work in the real world:-)
