I don't think that was a smart thing to do, just a panicked thing.

It was interesting seeing some people get straight up clocked by the shockwave while others were able to run (though perhaps with hearing damage, based on the last clip).

I heard 5000 lbs in other reports too....but it seems that's the entire haul, not what they exploded on scene. Footage of the 5000 lbs of fireworks looked like two pallets worth. I'm curious about whether the fireworks were removed before detonation or if they just got lucky they didn't go off too.

That was not just 10 lbs of fireworks exploding. It flipped over nearby cars and obliterated the bomb disposal truck, launching the 1ton lid over two blocks away. I know that's the LAPDs story, 10 lbs, but they aren't exactly known for telling the truth, especially if it's bad for them.

I've now read there were 40 coke can sized IEDs and 200 more slightly smaller devices all filled with unknown explosives. That sounds like 35lbs +- for the coke can sized ones alone (based on the weight of an unopened can), and who knows how much the smaller ones weighed, but there were 200 of them!!! Somebody screwed up big time putting them all in at once. That was way more than 10 lbs of unknown high explosives, and 10lbs wouldn't be safe to dispose of in a neighborhood. It should have been done in stages, starting with a test of just one, and a full evacuation of the block, not knocking on the 2 neighbor's doors and walking away.

At least it's turning out that most of the injuries weren't civilians, but more than one home is destroyed and many may have permanent hearing damage.

So nice of him to give his kid hearing damage.

Because that's not a car horn, it's a train horn. That can certainly cause hearing damage, or a heart attack if the victim has a condition. The volume makes it violent.
I also thought the reaction was out of proportion...as in too small a reaction....she should have thrown burning hot, grease dripping fries at his face endangering one of HIS senses like he did hers. ;-)

The first link is about China. Do they use the same vaccination schedule as we do? Do they use the same vaccine? How good is their record-keeping? Were there 1000 randomly sampled people from all over China, or from one specific place in the province?

They furthermore only mention that that one province has the mandatory vaccinations. Do the others? Are there a lot of unvaccinated people coming through the area that could disrupt the herd immunity effect? Like, say, a few tens of unvaccinated people at Disney?

The second link is someone trying to sell a DVD. There is absolutely no information there, just claims that have been refuted to the end of the universe and back. And some fearmongery correlation/causation conflation. Did you know that the Internet was getting built up at the same time as the skyrocketing Autism rate? I bet the Internet causes autism.

Third link: It is entirely believable that RIGHT NOW the measles vaccine causes more complications than the measles does. Because there are only a couple hundred cases of the measles in the US per year. It is all but eradicated, because of the vaccine, which means that it kills very few people.

If you go back before the vaccine, though, around 500,000 people had the measles a year (and this is probably a low guess, per the link). Around 20% of those had to be hospitalized. About four times more people died from it than now have fatal complications due to the vaccine.

No vaccine: (Possibly much) more than 500,000 people sick. 100,000 people hospitalized. 1,000-10,000 brain damaged. A few hundred dead (not a super fatal disease). Thousands more get liver damage, hearing damage, eye damage, other complications.

Vaccine: Assuming we're at a 90% vaccination rate, around 3,500,000 kids vaccinated a year. ~100 dead, per your link. 1000 with dangerously high fever. Deafness/seizure/brain-damage: So rare that a link to the vaccine can not be established. Autism: Completely fabricated and discredited.

This has a good chart comparing the relative danger, for equal numbers infected/vaccinated. If we stopped vaccinating, it would not take long to get back to where dealing with the measles was a dangerous rite of passage for almost every kid.

I can agree with that, but it's also sacrilegious to drive one in your neighborhood. I mean, I can run my Jeep with open headers and be a loud obnoxious dickhead that sets off car alarms as I pass too, but why? No problem with this on the track, at the show, or in his garage, but on the street it's not just obnoxious, it's dangerous...I'm certain that is loud enough to cause permanent hearing damage to anyone on the sidewalk or in the street...and that's bad...MmmmmK?

The problem with these types of vehicles is the short range and the super loud engine.

You may think "Gee why couldn't I fly this to work?"

The reason is because it runs around 140 decibels and would give all of your neighbors hearing damage as you took off for work.

Oh cool. What a nice start for this baby - having his hearing damaged.

I'd guess it was a mix of hydrogen and oxygen, or something else like acetylene and oxygen. Just a flammable gas on its own wouldn't explode like that.

They'll have permanent hearing damage.... When they build Mark II, I'd suggest some hearing protection!

While I'm all for early, vintage Scorpions fans enjoying their early stuffc, I'm a post-Lovedrive Scorp fan myself. I missed them by 2 days in San Diego when they recorded World Wide Live; still bums me out to this day.

With all that said, I can also say that I don't know that I'd ever go see them live again. I've seen them twice and they are, without a shred of doubt, the two loudest concerts I've ever been to. (One indoor stadium, one open-air) I KNOW I got some serious hearing damage from those two shows alone.

I've taken my upper-end at work before, in a sound proof room, and could follow with good detection accuracy up to 17.4 kHz (labmates typically maxed around 16.8... I win).

The lower end is highly dependent on the speaker, and tactile detection of vibration at very low frequencies can be confused for hearing. The upper end is also speaker and background dependent. If anything I thought this ramp test might show people where they have 'notches' in hearing: frequency ranges where they have hearing damage in one or both ears. BUT, with this poorly compressed recording on my cheap Monsoon pc speakers there were all sorts of fades and rises in amplitude.

I wouldn't use this to test hearing, or even test speakers, but it was fun rumbling around on the low end.
