The SWAMP! - Volume One

[drf]

does it always flip at 25 posts per page? I don't see to many rushing for the flip if it does!!

heres you pic everyone, enjoy!!

It's a tornado warning system. The bells are just in case cows flying down the road wasn't enough of a warning.

Does this mean the visual warning system only works with cows?

"Good grief, Ma!" "Did ya see that truck going by 50 feet off the deck?"

"Thank goodness it wasn't a cow, Sonnie." "Or we'd be havin' a real tornado!"

[drf]

how to tell what kind of storm you are experiencing:

newspaper = light breeze
unberalla = gusty storm
tree = galeforce winds
cow = tornado
truck = hurricane
giraffe = cyclone

whale/dolphin floating by = tsunami
whale/dolphin falling = offshore tornado
whale/dolphin passing horizontally = offshore tornado that decided to come inland for a bit.

Excellent!

[Sonnie]

Very good... and good morning!

Yeah... it's been so long since I've done the flippin' thing so I wasn't even paying attention that I was sittin' on post 24... and yes, it's always 25 posts. I could have easily gotten that flip, but just wasn't thinkin' clearly.

[Sonnie]

Where's everyone at?

We're all treading water waiting for the flip!

What are you doing down here in the Swamp?

There's no time for R&R now!

Have you finished our meter cal files down to 2Hz yet?

I guess we're just going to have to send the boys round!

[drf]

Hello!!!!

I am still here, I just didn't have anything to post. Umm... wait a minute.... I'm thinking... Ahhh yes:

So these two cows were in a field talking and one asks the other "are you worried about Mad Cow disease?", The other cow thinks about it for a minute then replies "No, I'm a chicken".

boom boom!!

roll on the flip!!

Then the first cow goes mad worrying about bird flu'!

theres a twist I hadn't thought of.

Were having roast beef for dinner tonight, I can't wait, my favorite parts the wing!!!

Don't forget to pull the wish bone!

[Chrisbee]

Beef is alright, I suppose.

I don't mind the cooking and the eating.

It's the moo plucking!

[Sonnie]

Plucking cows... I imagine I'd get tired too.

No mic to 2Hz... no cal files to 2Hz... 10Hz is the best I can do....

There has to be a way around this. What happened to the microphone mentioned by the dual Thigpen owner? This was supposed to be a cheap capsule.

I did a search for <infrasonic microphones> and discovered the clever chaps who monitor volcanoes also use cheap capsule microphones. There was talk of a corner frequency at 0.5 - 0.8Hz! What do they know that we don't? :-)

What is the answer? Borrow a microphone that can reach 2Hz and then calibrate your ECM8000 against it?

I suppose that means you need a sub that can reach 2Hz too or you'll have nothing to compare the microphones with.

Does this help our cause?

I have seen that RS mod before... maybe even posted it somewhere, but no one ever jumped on it.

I don't know anyone with a mic that has been calibrated or tested that low and yes I would need a sub to reach that low.

I'm probably not going to be the one to be able to provide much help below 10Hz... since my subs won't reach that low at a level loud enough to measure correctly.

[Sonnie]

I'll pay someone to do that mod on my RS Meter if it's reasonable, and I may borrow Rodny's 16-46+ which might get us to 5Hz, but I'm not sure.

[Chrisbee]

My SVS 16-46 response curve appears to sink at 45 degrees below 15Hz and 10Hz.

It should still have useful output to 5Hz.

Perhaps Tom V van help us on this point?

[Sonnie]

What does it look like below 10Hz? Have you taken a new measurement with REW4?

I realize it wouldn't be an accurate reading... just curious what it looks like.

[Chrisbee]

I'll have a go this morning.

This is what my IB looked like when I "pulled" the 10Hz graph down to 2Hz.

Not very helpful! It just drops like stone without help from the massive correction values at these VLFs.

[Chrisbee]

Righto.

SVS 1646NSD measured at port. Meter resting on a pair of socks.

old analogue cal file extended as a straight line to 5Hz -50 2Hz -70.

Read it and weep Mr Thigpen! 136dB @ 2Hz! Woohoo.

[Chrisbee]

More seriously:

I cleared all the cal files and reloaded my 2Hz -70, 5Hz -50 extended cal file.

Recalibration produced this graph:

(The curve down to 10Hz now looks about right)

16-46NSD meter resting on socks beside top port.

[drf]

This is what my IB looked like when I "pulled" the 10Hz graph down to 2Hz.

And I thought your IB looked like this:

[Chrisbee]

The last graph was nearfield at the port of the 1646NSD

This is one is at the listening position. Target 70dB.

It does. Sorry, I must have missed your point here?

What are you trying to say?

[drf]

Sorry, it was a literal joke, you said "here is what my IB looks like" and then posted a picture of a graph.
then I said "no i thought your IB looked like this:" And posted an actual pictue of your IB.

I guess some jokes just don't work on a text based medium.
