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

Re: The SWAMP! - Volume One


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.

Re: The SWAMP! - Volume One


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.

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!

Re: The SWAMP! - Volume One


Beef is alright, I suppose.

I don't mind the cooking and the eating.

It's the moo plucking!

Re: The SWAMP! - Volume One


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?

Re: The SWAMP! - Volume One


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.

Re: The SWAMP! - Volume One


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.

Re: The SWAMP! - Volume One


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?

Re: The SWAMP! - Volume One


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.

Re: The SWAMP! - Volume One


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.

Re: The SWAMP! - Volume One


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.

Re: The SWAMP! - Volume One


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.

Re: The SWAMP! - Volume One


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

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

Re: The SWAMP! - Volume One


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.
