There's a DVD, now out of print, called "The Mighty Saturns." It's all about the Saturn V rocket, which put men on the moon and is still the largest and most powerful rocket ever made. It had 7.5 million pounds of thrust, and the stored energy of something like 25% of the Hiroshima atom bomb.

It's a 3-disc set, and Disc 3 is all remastered launch footage. The launch of a Saturn V was said to have bass down to 1/4 hz. This DVD pretty much captures it all.

First, from a longer shot, where the bass isn't quite as deep, you get this, which is very, very loud bass from 10hz to the mid-20s hz:

But oh boy, if you have the system, you can enjoy this, which is a close-up shot of the launch of Apollo 8. Bass seems to go down darn near to DC. Otherwise known as ZERO hz.

As a gift to the bassheads here, I made .wav files of the two chapters, and they are here:

The 1st one: http://rapidshare.com/files/128454213/Saturn_V_no2.zip.html

The 2nd one: http://rapidshare.com/files/128454214/Saturn_V_no4.zip.html

Fair warning -- if your sub cannot go below 20hz with gusto, you'll likely either not hear and feel much of anything, or you'll blow up your sub. If your sub can go that low, then make sure things are bolted down and secure all over your house. Play these at your (and your sub's and your house's) own risk.

Let's start a report of your sub and what you got out of it. Mine's a Velodyne FSR-18. I got lots and lots of shaking and pressure, with very little audible sounds other than some crackling made by the rockets. My room's about 5000ft^3 and cement, and I thought the whole building was going to come down.

EDIT: I wimped out at 92db, uncorrected. I was afraid I'd damage my sub.

Spacecraft films has various series of different Nasa missions.

I think this very one is available. But, a fair amount of similarly low content can be found them. They have excellent audio of nearly every launch. I don't own them, but my bro in law does. It makes his sub smell funny when he runs it even a little loud.

Ohhhh Thanks:D I'm gonna try this out. I don't have any 0-5hz output:rolleyes:, but I'm solid from 8 or 9 hz on up.

Have you tried the Fireworks demo thats downloadable from Danley Sound Labs? It's got some really high level 9-10hz stuff on it. I wonder if anyones done a waterfall of the end finale on that...

Here's the finale. :)

http://personal.inet.fi/private/ilkka/graphs/fireworks1.jpg

It sounds like everything is coming out of my front speakers. However, I took the cover off of the sub and the driver is moving. Just a very low sound when I put my ear up close to the sub.
I won't play it too loud cause I don't want to damage the sub. I am not sure how far to push the sub. Definately some low stuff going on.

Thanks Illka! Not quite as hot in the 10hz area as I thought but there's some good nugs down below.

I will be testing these in a few minutes. I will let you know what spl(uncorrected) I hit. I will also run the fireworks demo. I hope the disc works.

There are a few people who hang out in the $20,000 section of the Forum who have one or even two Thigpen Rotary subs. They can reproduce signals down to DC. (And I don't mean Washington). In reality, I'm not sure that even the Thigpens can do 110 db at 1 Hz, as advertized. Still, nothing else comes close. With the Thigpens you don't have to worry about damaging your subwoofer trying to reproduce lift-off of the Saturn, but you might have to be careful not to cause the doors move back and forth.

Shouldn't your listening room be pressurized with all that white and pink down low.:D:eek:

The disc would not work. I will have to re-download tomorrow.

What was the problem? The files of the launch are simply the .wav files zipped with a copy of the .jpg of the waterfall in the zip folder. You should be able to burn them to CD.

Well if the title of your thread is accurate... "Lowest, loudest bass ever. Nothing else comes close"...then anyone who follows this "Bass" forum should be buying this set.

You definitely have me interested.

Same thing here with a space shuttle launch.

Hmmm....

I like space history and I love deep, deep bass. I guess this will have to be purchased soon. :D

Most of the sound you hear in films is fabricated and only small portion of it would be actually production sound, but it’s still a trilling listening experience.

I’d hath to look around for the region 2 DVD version I think my JBL 4645 will play that no problem what so ever.

The disc is coded for all regions, at least according to the back of the jacket.

Anybody got output #'s for the Saturn launch yet:D?

Anybody toast anything yet?

Here's the finale. :)

http://personal.inet.fi/private/ilkka/graphs/fireworks1.jpg



That is a beautiful thing Ilkka!

I love the Finale track. At about 3:20 in when the real fireworks start detonating it sounds killer if your system can really belt it out cleanly. I had some friends over to watch the Griffin vs Jackson fight and played it for them before the PPV started. The looks were priceless.

I used a DVD RW. I will use a cd-r next time.

Gotta try it in Randy's truck, with all that gain will be killer.

The BD disk "Roving Mars" has a nice deep sounding launch in it.

Are there any more impressive launch recordings? I've been searching for one. Something that will drop jaws. Is this track impressive on a good setup or is there a better one?

I've hear good things about The Incredibles rocket launch but is there something specifically just a launch video or audio?

Holy crap! I think that was the definition of being assaulted by bass. I feel a bit bad for my living room walls after that. For anyone that hasn't listened to it yet, it sounds/feels (at least to me) like if you were to extract the sound effects of the ground cracking during the War of the Worlds pod emerging scene and play it in a loop for 3 minutes!

Thanks for the full body massage!

If that was in blue-ray I'd buy it today....

I can't find it anywhere! Places have to order it. Damn! I want it. I am having people over tonight fpr the Klitschko fight and would love a great demo disc.

“In the Shadow of the Moon” (2007) is loud and low with enough pulsating shuddering low end that moves the door in the hallway 22 feet away within the flat.:D Single JBL 4645 tuned for lower end LFE.1 only.

Do not play these wav files as they are badly clipped.

http://xs129.xs.to/xs129/08292/cliporama319.png

I guess the single digit bass as sampled by the program is due to the clipping?

Do not play these wav files as they are badly clipped.


Just out of curiosity (I don't know too much about audio conversion), your conversion from wav to mp3 couldn't have caused some of the clipping, could it? (the name of the file displayed in your image is a .mp3)

Conversion doesn't alter amplitude (unless you expressly tell it to). Here is the wav opened directly in Pro Tools. The clipping either occurred during recording (mic overload, mic pre overload, limiting, etc) or when ripped by the original poster). As such, this will not sound good on any system.

What are you saying? The waterfalls of the Apollo Saturn V where fake a hoax. :D

Thanks for clearing that up.

I'm the OP. I checked and the DVD is clipped, so it was mic overload at the time, or a mastering decision. Still, I question the bald assertion that it won't sound good on any system. It technically won't "sound" at all -- it should be an infrasonic massage and room shake.

I have a system that's as good as many and better than most. I certainly couldn't tell that the 10hz was clipping. What, exactly, would a 10hz clipping "sound" like? I'm quite attuned to clipping and overload in the audible spectrum, but not in the infrasonic spectrum.

I have you got any idea what the SPL db from that thing was, HUGE no wonder they have 4 mile viewing limit.

I can’t be asked at this time to Google the SPL db level average of the Saturn V my head is aching so you type in keywords I’m just relaxing tonight.

Ahhh. I called it! I thought it sounded quite strange. You can clearly hear the higher frequencies cutting in and out. Note you may not hear the higher frequencies at all unless you've got it turned up fairly loud(at your own risk).Yes it also does sound quite bad. It's more of a curiosity than anything due to the clipping. However, this still has more bass than any other track I've ever experienced regardless of the clipping. I just wish that it sounded like what a stereotypical rocket take-off does.

Is anyone surprised that a saturn 5 launch clipped the recording mics really?;) It's gotta be what 170-180db? Not to mention sonic booms.

Yeah I would say that’s more or less spot on. And if Muppets want to play those levels in the home without take safety precautions of the use of earplugs then good luck.

FAAAAR louder than that, people always see these spl #'s for specified distances and assume that thats how loud it is, a Jet taking off can easily reach 180 dB if your within 10'. The funny thing is, the folks with car stereos assume that because a jet was measured to have 150dB at take-off that their stereo must be louder. Just because a stereo hit 160dB at the dash does NOT mean its louder, it just means that it was measured closer, most of those jet recordings are done at between 100 and 300'.

The calculated near field acoustic output of the saturn V was 220dB! They didn't measure it of course because the jets melted the concrete beneath them, steel turns to gas at those temperatures, any recording equipment would be instantly demolished.

I seem to remember watching a program many years ago with (Sam Neil) called “Space” and in one of the episodes veteran astronaut (Story Musgrave) commented about the space shuttle from the inside he says “its 130db on the outside it’s the complete opposite.”

Slight clipping is audible as clicks/hardness to the sound. Severely flattened tops like this will, and do sound like utter crap. I tried the wavs on my IB and even at low volume it was just crackly junk.

If you want I can take your favorite song and clip the hell out of it so you can see how it sounds :)

Unfortunately, modern music has light clipping throughout and some albums have quite a bit. Sound quality is at an all-time low as the "loudness" race continues.

For us simpletons, who also accidentally have this set, what minute of which disc has all this intense bass? Sorry to be pathetic, but I can't read the smallness on the OP's graphs, if they even have the info - which I hope they do, and the wav files don't seem to help either.

Is anyone else in need of help? I have these discs, yet don't know where to start to find these segments!!?? Sorry/thanks!

I am so glad I resisted the urge to really crank it up loud.:)

The funny thing is that most of this music is already at 0 to -3dbfs most of the time, then when it is broadcasted on the radio, they take what little dynamics were left and compress the hell out of them until even the most compressed songs sound even WORSE! Unfortunately, recording equipment and electronics need to achieve lower noise floors in order to really capture full real life dynamics and translate them accurately in our living rooms.

That's not really responsive. You won't be hearing 10hz. You'll feel the pressure waves. What does a clipped infrasonic wave feel like? Or, even more to the point, if I had a non-clipped version of the DVD, how would the 10hz differ in what I feel as compared to the clipped 10hz?

Army, sonic bombs are in the region of 212dB.

Don't think it's that loud for the recording (170dB), you gotta be real far away from a rocket launch. :) A real big firecracker/thunderflash in an enclosed room is 170dB thereabouts.

Army's probably right about the level at the launch pad 200+db where the concrete is melting and all of that. I was thinking that it must be 180db or so a few hundred yards away.

So anyway, I thought I'd have a go at this again and post a video for all to see. I recorded 98db at 1 meter with the first of the two clips. The sub had more to give, but why risk it? As it was, my whole house felt as if it were about to fall apart.

The sub's a Velodyne FSR-18. Not the most competitive xmax vs. a more modern sub, but the 18" driver helps make up for things.

You can hear 10hz. I play a tone generator when people come to hear my IB and everyone can clearly *hear* the difference between 10, 12, 14, 16, 18h and 20hz.

http://www.geofex.com/effxfaq/distn101.htm

Quoting from that article,

"As you can see, the sine wave has been amplified a lot, then clipped off so that only the starting part of the sine wave remains. This has even more harmonics than the moderately clipped one. The result is a heavily buzzy sound."

So even if you clip 10hz, it will create more audible distortion harmonics and since the clipping is a total "flat top" rather than a softer type of clipping as you might get from analog gear, it will sound extremely harsh.

If you really want to listen to 10hz at high levels, use a tone generator :)

The fking Irene scene in Blackhawk Down has an 8hz fundamental at high levels, you can't get much deeper/louder than that. Even on my IB the 8hz part isn't that "audible" and the woofers are really moving.

Anyone familiar with the 3 volume CD series Sonic Booms from Mobile Fidelity?

7.5 million pounds of trust against wimpy Black Hawk are you kidding me no why impossible the Saturn V RULES!

Screw Black Hawk Down it’s for pu$$ies.

Okay I’ve watched Twister more times today than most of you I guess including projected. So I’ve got my DVD copies of In the Shadow of The Moon and Black Hawk Down I’ll test each with the SPL db.

First the Irene moment then I’m going to get the disc out DVD player and spin In the Shadow of The Moon and if the needle bends bugger Irene.

The mighty Saturn V rocket wins! It went OTT on Irene by 13db.

I haven't seen any professional evidence that humans can "hear" anything below around 15hz.

http://hypertextbook.com/facts/2003/ChrisDAmbrose.shtml

Can you link something? You may very well be hearing something resonate at a higher frequency due to the movement of your speaker at 10hz though.

Same with high frequencies 20Khz is best maybe when your young and you know the difference and its only going to last for short while until it disrepairs and the most might be around 16Khz if your lucky enough.

The Saturn V in loudness left “Irene” Black Hawk Down standing on the pad.:p

I used to use a signal generator for a while that I liked. Found out way later by running it thru a spectrum analyser that it also has tons of harmonic distortion. It could be that you are hearing the upper harmonics and NOT the main fundamental in that case. It fooled me too. I thought I had SUPER hearing below 20hz. :o Heheheh.

I could be wrong. Your generator may be better than the one I used to use a few years ago. I wanna say it was the NCH (or something like that, its online for free) generator. Has all sorts of output modes and you can choose frequency and after an update it had sweeps. Unfortunately, all the sinewaves were loaded with harmonic distortion. D'oh!

I wish there was a recording of Mount Krakatoa.

The explosions were so violent that they were heard 2,200 miles (3,500 km) away in Australia and the island of Rodrigues near Mauritius, 4,800 km away; the sound of Krakatoa's destruction is believed to be the loudest sound in recorded history, reaching levels of 180 dBSPL 100 miles (160 km) away.

I bet that would break any subwoofer.

Did you only look at the cover art? Tsk, tsk. The discs have a variety of heavy bass, including shuttle lift-offs and re-entry booms. Unlike the Saturn recording, this stuff is top quality, down to 1/8Hz and average 144dB, with no clipped signal.

No I haven’t heard of that one?

I have several IMAX DVD formats I think you know the ones I’m talking about?

I have Apollo 13 dts THX laserdisc and two different region 2 versions and the signature THX laserdisc.

Funny I’ve got Apollo 13 region 2 first edition under the scope now testing it for my own in home use with some changes to the BFQ2496 while monitoring directly on the spectrumlab while listening to the LFE.1 content and making some different changes to the EQ to soften smoothen out the peaks for a more greener friendly level.

I’ve got to repeat a few more tests now with LCRS and get the levels on the barograph looking more normal, and I wish I can say the same thing about my cat Sooty as he really down in the dumps at the moment.

I have For All Mankind VHS PAL to DVD-RW and that is cool documentary.

Plus a few other films here and there that depict the Saturn V and Space Shuutle. Star Trek Assignment Earth, Space Camp, Space Cowboys…

Shall I continue :D yes I’d like more please yes [rubbing my hands together]

144dbc is far too loud and human hearing threshold is 130db for pain. and I don’t fancy 130db its impractical when you have volume control to turn it down for comfortable listening.

Real life is something you can’t control unless it’s some wanker across the road with a load of PA speakers being unsociable and nothing like a good tonic of human piss :D pissing over his amps will soon shut him up.

I cannot download. It keeps saying, "error".

Robert, did you get it working? I was getting that too, but then I saw that you can only download one at a time. Don't know if that was the problem you were having.

Question, is this bass straight from the rocket itself or was it reproduced?

this was pretty deep

Anyone have the waterfall for the Apollo 13 launch on the Telarc SACD "The Big Picture"? (track 6) According to the liner notes the infrasonic frequencies go down to 5HZ. "Recording of the actual launch on Feb. 3, 1995 was made using 5 microphones positioned as close as 450 feet and as far away as two miles. Positioned where past attempts at recording launches have actually left little melted nubs of metal where a microphone once was."

Much scarier were the tornado recordings on tracks 15 and 24. The effects in 5 channel surround really made me feel like a tornado was decending on my room.

I have four MFW15s, by the way.

I read through this whole thread intending to post about this, but you beat me to it!

This disc has some pretty good low stuff in it, but I've only ever listened to it in my car audio systems... the best one for infrasonics being a Cerwin Vega Stroker 15" sub in a sealed box. I've never measured or analyzed the output, so I have no idea how much, if any, of the 5Hz information I was hearing/feeling on the Saturn V track, but I was always intrigued by the recording notes that you quoted.

Seems to me they went to great lengths to record everything in very high quality, hopefully without any clipping. I cranked that CV Stroker pretty well on numerous occations and never hurt it.

Ohhhh Thanks:D I'm gonna try this out. I don't have any 0-5hz output:rolleyes:, but I'm solid from 8 or 9 hz on up.

Have you tried the Fireworks demo thats downloadable from Danley Sound Labs? It's got some really high level 9-10hz stuff on it. I wonder if anyones done a waterfall of the end finale on that...

The Danley Fireworks track is indeed an impressive demo. Has anyone tried the Train Starting Up track found here: http://www.danleysoundlabs.com/TrainStart.wav

While it isn't as explosively impressive as the Fireworks, I think it showcases low freq rumble very well. Anyone happen to have a waterfall of this?
