Keaton Jones... Bullying needs to stop

I remember when the United States military had to rein in what a Drill Sergeant could say because some of it was considered "bullying" or offencive. Such as saying " you shoot like a faggot" can't say that anymore LOL.
Blame how politically correct this country has gotten.
 
I'm from the school of toughen the kids up. My dad showed me how to box when I was 10 years old. I was kick boxing by the time I was 14.
 
I learned judo as a kid and submitted a bigger bully on the ground in a street fight. Got him in side control, he could not do anything, he struggled for about 3 minutes and I rode him like a bronco just kept adjusting my position to stay in control. The fight never progressed he was immobilised but I could not do anything further. I made him yell out loud that he gives up and that I won. I then let him stand up and put my hand out to shake hands and he punched me right in the mouth and put my teeth thru my lip then punched me in the stomach and dropped me like a bag of shit.

I was so shocked that he did that, it was like he broke the rules of the universe and how did god let him do that. I felt cheated and disoriented. Kid was tougher in the mind than me and was like fuck your rules - my decaying old brain has never forgot that revelation decades later. The spell was broken I learned what reality is.

I realised then decades before MMA was invented that you need a stand up game and finishing moves on the ground. Judo failed me, I was proud I submitted the guy in side control but learned control is not winning or finishing a fight.

I then switched to striking arts ie boxing.

Another bad thing about ground fighting is you prolly get jumped by someone else when you rolling around on the ground anyway.

Remember Chuck Liddell - strikes stop fights instantly, take down defense beats rolling with someone, scooting out and escaping from the guard and standing back up etc are the simplest skills and most effective in a fight.

Lol at spending 20 years to master all this technical grappling shit, waste of fucking time.

Sounds like some alt right horseshit to get people to side with them

You really think drill sergeants magically care about your feelings or care about being pc just because that one black dude became president?
 
I REALLY hope this is true

It is true. The USMC also played Death Metal before taking Fallujah. We also used it in Afghanistan. Loud as fuk to keep those assholes awake at night. Sleep deprivation fuks with the toughest mofos out there.

Danley Sound Labs is an audio company that focuses on high SPL horn loaded drivers. Amazing technology, really. They developed a speaker for our military called the matterhorn. It is a 20' metal connex turned into a speaker. It pushes audio at such high SPL the human body gives up, you stop fighting and give up.

The rumor is they used it more than a few times over in Afghanistan at Tora Bora and those related caves. Is that a real claim? I have no clue. The pressure it produces will put every single person reading this on the ground as fast as hollow point though, that I can guarantee.

Danley Matterhorn Sub banned from NSCA Demo
Feb 22, 2007

The Matterhorn reproduces program material in the frequency range of
15 to 80Hz continuously through a system of 40 low frequency drivers...

Tom Danley will unveil the most powerful subwoofer ever created at the NSCA Expo 2007 in Orlando, Florida in March. Initially designed for the military and dubbed the Matterhorn by Danley Sound Labs, the record-breaking subwoofer is housed in a shipping container measuring 8' x 8' x 20' and generates 40,000 watts.

The Matterhorn reproduces program material in the frequency range of 15 to 80Hz continuously through a system of 40 low frequency drivers. The extraordinary technical specifications of the Danley Matterhorn include a -3dB measurement at 12Hz and an SPL of 105dB at 250 meters (just over 270 yards).

Remarked Mike Hedden, president of Danley Sound Labs, "The Matterhorn goes two octaves lower than any sub commercially available. At the mouth of the horn, it achieves 160dB and moves ten inches of air. You can dry your clothes with it. You can move a Honda Civic with it. If the Civic's parked on a decline, the Matterhorn will knock it over."

When asked who will buy such an audaciously powerful subwoofer, Hedden laughed, "The military, of course, that's why we started this project. But we also plan to scale it down. Our customers in the professional audio world will be able to purchase smaller versions, which, while less powerful than the full-blown Matterhorn, will still blow away any other commercially available subwoofer, almost literally."

Inside and outside of the Matterhorn with a view if the amp stack used to drive the connex. Guys, this is literally the world's loudest speaker and half of what it produces you don't hear, you feel it. When you start hitting the human body with 100dB+ under 30Hz with peaking audio into 150dB+ you win. Doesn't even matter if they cover up their ears, you win.

2 places you can hear this beast is at Infocomm and maybe (big fat maybe) at Cedia in a few years when they shrink it down to residential size. They have reduced it in size so you can have it in a stadium, residential will be next and it will still be big in size. Too big for most homes. It will have to be built in wall or something like that in a home theater room.

Danley Sound Labs is the future of how audio is used. Horn loaded drivers use exponentially less power and produce higher SPL. The future.
 
@Ickyrica is this actually true, not the existence of the loudspeaker but its ability to disable combatants with low frequency audio.

No offence but I would have be more inclined to believe a viable directed energy weapon would be in the high frequency range which anyone can easily prove with a trip to an electronic hobby store.

Debilitating base frequencies I can not believe is capable of being weaponised - the so called "poop note" is IMO urban myth.

Not saying your wrong I just can not believe it without proof.
 
150dB will put anyone on the ground. Fire alarms are rated around 128dB. Every 3dB increase in SPL is double the audio to the human ear. We as humans perceive about 6dB-8dB as double but that's because we have flawed hearing; it degrades as we get older. Extreme flawed hearing is closer to 10dB.

Going from 128dB to 150dB is an exponential increase in power, not even remotely subtle. The brown note is a rumor.

From a mythbusters write up...

Explanation: The brown note, also known as the disco dump, is a subsonic frequency around 9 Hertz (Hz) that supposedly rocks so hard, it causes people to lose control of their bowels. Conspiracy theories about this nauseating tone go back to before World War II, and some people believe government forces belt out inaudible brown notes to disable unsuspecting audiences.

MythBusters Adam Savage and Jamie Hyneman tracked down some alleged brown-note audio files online and blasted them at various frequencies, attempting to hit the not-so-sweet spot. Adam sat at the center of the 24-speaker brown-note symphony, and his body absorbed all the brown-note vibrations projected at an undetectable 5 Hz up to 20 Hz.

When none of those frequencies struck a chord with Adam's stomach, the MythBusters team pumped up the volume to a deafening 128 decibels. Adam could feel the music pumping against his chest, but it had no physical effects below the belt.

All of the brown-note frequencies failed to stir the MythBuster's bowels, busting the myth - and preserving Adam's dignity.
 
Generating 150db around 20Hz takes a shitload of infrastructure if its even been done at range which i doubt and military applications would be ranged. but anyhoo stick your fingers in your ears and you there goes your 150db down bigly.

So huge infrastructure zero range and defeated by shoving toilet paper in your ear does not a weapon make IMO.

I watched the mythbusters link below, Adam is point blank range and a set of earphones he was fine, no debilitating effects, he enjoyed it. A few feet away the operators were fine. That's the biggest civilian experimental set up ever done as far as I can find.

Now the audio weapon used recently on the American embassy staff in Cuba is very vague, I have been following it. The symptoms in no way debilitated anyone in a battlefield sense ie instantly or loss of body control although they did get sick. Government speculates it is an audio weapon wether it's ultra or subsonic is unknown. Not even confirmed its a directed energy weapon or not.

Its the same idea as a concussion grenade. The grenade is on a very small scale compared to this speaker tho. Upon explosion it disorients the enemy and deafens them thru concussion. Rendering them useless and defenseless for a period of time.

That black lives matter piece of shit that was sniping only white officers in down town dallas a year or so back went and holed himself up in a community college. He put himself in a narrow hallway where there was only one way to enter and he had the only advantage. The SWAT sent in a robot armed with small amounts of C4. He was killed thru concussion. In otherwords his outward appearance was fine. A little blood coming out his nose and mouth. But his insides were crushed.
Same concept

Trukk is in the right direction.

You're comparing apples to oranges, or maybe a civic to a bugatti is more like it. I'm driving north right now which means no traffic so I'm doing 85. I'll show you how massively different this speaker is in comparison to anything else in the planet and just how much power you need to push it's electrical limits, when I'm not driving up 93.

The support needed to deploy this speaker is certainly something the US military can do with ease, btw.

4 or 5 of these will destroy. Bigly.

So first and foremost I want to address you again having zero faith in my armed forces. This isn't the first time either. Let me ask you a question. Why wouldn't they be able to easily support the speaker? You must have logical and factual reasons considering you're so adamant, right? Please, do tell.
if its even been done at range which i doubt and military applications would be ranged

Do yourself a favor and read with accepting eyes. You might actually raise your ceiling a bit, but I doubt it.

The Mythbusters brown note was a legit test, but it was grossly flawed. The audio company and the engineering staff running the test were perfectly suited for the task (world class in some regards) but the use of audio in that context is garbage. The area they used has zero correlation sonically to caves in a mountain range, exactly the polar opposite in fact. Two nagging issues I also have is that PPE he has on in the video and the listeners proximity to the source. All I'll say is that headphones easily knock 30dB+ off. If used in Tora Bora my guess is the Taliban didnt run out to Cabellas or Home Depot to grab PPE. Proximity matters because of the wavelength of the notes; they need distance to develop. Bass wavelength notes are long so sitting next to the source like they did puts you ahead of the audio. It's like a horse kicking you; up close it doesn't hurt so much, at full extension it will break your bones.

So, here are some facts about what Mythbusters did and what the Matterhorn does.


Mythbusters

Meyers HP700
-139dB @ 1w/1m peak
-28hz lowest tone accurately reproduced
-2250w peak (27000w total w 12 sub cabinets)

They used 12 of these in an open area, with ear protection. Pretty simple and safe experiment. Remove the ear protection and replace it with cotton? Tissue? What did you say? Fingers? That's a good way to render yourself defenseless.
stick your fingers in your ears and you there goes your 150db down bigly.


USA armed forces

Danley Matterhorn
-152dB @ 1w/1m continuous, spec also called for 10dB of headroom
-15hz lowest tone accurately reproduced
-40000w continuous
-105dB at 205m

These are some things you want to pay attention to:
-Danley has 13dB of gain over Mythbusters
-they can accurately replicate a lower tone, by almost 3/4 of an octave!
-applied power is 40% higher
-Mythbusters setup is rated as peak
-Danley setup is rated as continuous

This is when it gets interesting. Some simple facts of life are a 3dB increase in SPL is doubling the audio power and cutting distance in half gains 6dB. That means if you deploy 10 Matterhorns you will have 134dB at 205m, 140dB at 102.5m, etc. OR simply add 3dB to the spec every time you double the power. The math is simple. This brings another question to mind for you. What do you consider "at range"? 205m is well over 650' so is that far enough? Doesn't matter in a cave system but you wouldn't know that. Don't worry, you'll know soon. Have some faith in the military, damn.
if its even been done at range which i doubt and military applications would be ranged.

And let's move on the infrastructure shall we? The Matterhorn has a built in power generator and signal generator, and yes you can connect line level equipment.

Mythbusters - 225 amps total at 120v
Matterhorn - 333 amps total at 120v

I won't even get into playing games with power to make the system more efficient. I want you to keep pace.
Ended that inquiry pretty frigging quick. 333 amps is a far cry from a shitload of infrastructure. To you? Maybe it's a lot but to people in the real world, it's nothing special.
Generating 150db around 20Hz takes a shitload of infrastructure

Are we done yet? Oh gosh no, I have more. Let's dig into the open space used by Mythbusters and compare its sonic qualities to those of reverberant surfaces like cave walls. When you have open space you have nothing. Your audio travels searching for absorption, much like waves move but in the open they just die out sonically. In a cave you have reverb, reflection. As your sound waves are being produced if you push the speaker closer to a wall you actually have some gain in amplitude, naturally. Depending on the circumstance you can achieve gain 6db+ what is capable by the speaker system alone.

Another question. Do you think our military is capable of gathering 10 of these Matterhorns and jambing them into caves in Afghanistan? I do. Easily. Has it been done? No clue but your idea of what these will do when utilized correctly is deeply flawed.

Layman's terms is this, 150dB+ in a real life scenario will render you useless. In a cave will be worse than anything you would ever want to experience. You can say no all you like but the highest level audio you will ever hear is a 128dB (approx) from a fire alarm system, in quarter second bursts. What the Mythbusters heard was a broken down version of low frequency audio (subwoofers that are over 20dB out of their operating range, 1 octave!! Which is a huge deal) while sitting closer to the audio source than the wavelengths ability to develop and this was all done through heavy duty ear protection (PPE).

Mythbusters is stepping on Danleys dick if you haven't noticed.
 
To circle back to the original post, i feel bad for that kid but as a father id teach him to stand up and punch someone with a stright right. Goodby nose and goodby bullies.

Damn
 
All factual and completely irrefutable

Fun facts, AC/DCs 'back in black' tour was 130dB continuous. They were legally forced to drop the volume by half. Their 'for those about to rock' tour was utilizing 45000 watts for the entire concert series.

Think about that. 45k watts being pushed out of a human sized opening, in the Matterhorns case, as opposed to massive apeaker arrays at a concert.

These speakers are out of this world. Who the fuck is Bose?

They are actively used right now on most of the U.S. Navy's fleet. Alot of the technology is still being perfected by R+D in the U.S. Army and USAF. It would be a great addition for perimeter security at a FOB(forward operating base). Used in Tora Bora?? I have no fukin clue. I was attached to a USMC Recon team performing Surveillance and Reconnaissance far away from Tora Bora when it happened. Wouldn't be surprised if it was used though.
 
Sound%20Attenuation%20Graph.jpg


First how is this relavant to weaponry "-152dB @ 1w/1m "??? anyhoo....

See above graph lowest frequency is 25Hz, @100m we have a 10db loss. From papers I could access for underground (mines/caves) absorption you are looking at .03Sabines at typical mining equipment frequencies which we can reasonably assume is bottom end noise although most likely not 15Hz 195db.


Looks like a pretty lossy system to try stop a army of deranged jihadists IMO.

As far as PPE, come on man, armies can, should and do protect troops against all manner of chemical and biological attack and have done formally since WWI. dam right they will supply troops with a set of headphones that weigh and cost almost nothing relatively and take up basically zero space in a pack.

I thought originally you said such weapons were deployed?? Can find a quote if you want and now you seem to be just saying it is theoretically possible but hasnt been deployed??? Please clarify.

I have followed directed energy weapons for some time and am aware of police use of high frequency audio to push back protestors.

Modern politics increasingly demands non lethal weapons of compliance, casualties and gore on television don't get you votes so DEW's are getting a lot of attention. To obliterate your enemy tho I would like a link to these lethal subs.

And let's ignore reflections off walls at low frequencies, not happening.


FYI my little brother is a sound guy for live music venues indoor & outdoor, we have discussed this a lot. I am a sound snob for sure so actually enjoy the chat and you have taught me stuff.

relevant? Its the baseline for all of your math. It's extremely relevant.

that's a basic signal loss chart with an average ambient atmosphere as the medium. Its pointless without the thing we talked about above: 152dB at 1w/1m. That chart changes drastically based on what driver is pushing the audio. 139dB looks a while lot different on your chart than 152dB does, across all hertz. Also, nothing used for work in a cave system will even begin to sniff at 195dB, forget about what Hz.195dB is not able to be reproduced by anything single thing man has ever made at 1w/1m. Some of the loudest jet take offs ever recorded were 140dB at 100': 143dB at 50', 146dB at 25', 149dB at 12.5', etc. (195dB isn't something we can physically comprehend) For reference ear drums begin to rapidly break apart over 160dB. Even those fancy ear muffs can't stop that.

As far as PPE, come on man, armies can, should and do protect troops against all manner of chemical and biological attack and have done formally since WWI. dam right they will supply troops with a set of headphones that weigh and cost almost nothing relatively and take up basically zero space in a pack
but you are making a mistake in calling the taliban an army. do you expect thousands of fighters in caves to have these on a whim? Amazon prime doesn't apply in this case. There is zero chance they had hearing protection waiting for the masses.

I thought originally you said such weapons were deployed?? Can find a quote if you want and now you seem to be just saying it is theoretically possible but hasnt been deployed??? Please clarify
Has it been used? I've said I have no idea since word one but in the capacity laid out before you it's an unavoidable fact that audio, at any frequency, can render you useless.

I'm going to sound like an arrogant fuck here and I can't prove it because of identity reasons but I'm more than a sound guy. I've turned down engineering roles at Bose. I get contracted more than I'd like to train people on live sound boards like Soundcraft GLD and newer series rigs, I have my name on more than one platinum artists studio efforts, I've worked on sound effects and foley for a Pixar movie. This year alone I would safely estimate that I've designed, installed and programmed around 5 million in audio systems. I literally just finished a brand new half scale collegiate athletic complex and football field. It's who I am.

To obliterate your enemy tho I would like a link to these lethal subs.
stop with the straw man efforts. I simply said that 150dB will render you useless.
