256 db

how the fuck would/did they measure this?

Measure air pressure required to remove clothes using air compressor or something, then convert psi to dB

You'll still never be able to reproduce that much air being moved, with subs. Yeah vehicles pulling off crazy ass hair tricks is moving A LOT of air, but still NOTHING compared to an abomb explosion, and we will never be able to reproduce THAT much air being moved.

^very true.

I watched this Hiroshima documentary, this random asian dude who lived quite a while away saw it go off, then he saw the wall of dust moved by the shockwave. It slammed him into the other side of the room. So lets make that our goal first, then we remove clothes

Old topic, it was posted on here before.

And I will say what I said before.

194dB is the loudest SOUND possible.

Anything over that is an over pressure shockwave and is considered an explosion. Not sound. It is non-linear.

Who the heck is right? I heard it was 186?

I dont know who said 186, but 194 is a proven, physics fact as the loudest sound possible.

[HHR Ed]

But, in the past, I have stated that 185dB, In My Opinion, is the loudest I think we can achieve in SPL competition with todays autosound equipment.

Serious advances will have to be made to exceed that number.

And the Term Lab is only designed to be accurate up to 185dB.

Good thing 182-183 is the top of the chain right now.

you still can't hit whatever it is because you would need to get it down to a pure vacuum.

Yup, 194 represents a perfect vacuum. thats why that is the limit of sound. You can technically keep compressing air infinitely. But it will be non-linear. (more compression compared to vacuum.)

So its just a shockwave of compression. Basically an explosion.

An explosion has sound, but an explosion is not sound. If that makes sense.

x2^^ krakatoa susposidly did a 285db when it went off, and they said that it could be felt in texas but thats not sound

a sound has somewhat of resonant frequency to keep up with, anything over 200 will kill anyone just by shock wave alone, and cant be measured that high anyways

this had to be a guesstamation

but what really gets me is, what is the very first db reading meter ever created?

cause they would halfto base the term-lab on something for it to be so reputable among spl ppl and what knot

i watched that mythbusters woofer deal they had and that one dude with the jbl van said that anything above 165db could cause permanent hearing damage, and or bleeding from the ears

i think my truck is around the 135ish db wise on a good day, so with a 160+ i would worry more on a brain hemerage from all the vibration and pressure

if u could do a psi to db ratio, at witch depth a diver would halfto go for ears to be would equal witch db?

Tell me this, doesn't 160dB+ hurt the mics in Term Lab, meaning they need to be recalibrated?
