Loudest Db Someone said?

[the727kid 10+ year member]

Does anyone realize the highest possible dB is 194dB?

EDIT: The wiki source says 191, but I thought it was 194?

Bullshit I'm pulling at least 200+ right now.

Actually we studied the limit in dB of sound is 194 dB. At that level a lethal overpressure shockwave is created.

194 dB represents a perfect vacuum. It is possible to have a higher dB but it will be distorted and not considered sound, this will be like an explosion where the compression wave would be greater than the rarefraction. You can technically have limitless compression, but rarefraction to vacuum limits SPL to 194 dB.

Of course this is in air.

Atomic basts are estimated by taking a reading several miles away and figuring in the loss over that distance. So its all an estimate.

The NAVY has sonar capable of 220 dB but this is under water where it is much easier to create high SPL and vacuum and rarefraction is measured differently.

The loudest I have heard anyone say is 200 dB though that they have hit in their car, I just ask for proof and they can never show it.

not sure where your getting your info from...but u can go above 194db's..//content.invisioncic.com/y282845/emoticons/biggrin.gif.d71a5d36fcbab170f2364c9f2e3946cb.gif

Also, theory indicates that the limit in SPL with todays autosound equipment and power levels would be about 185 dB. and even at these levels you need serious reinforcement, i.e. a very well built extreme car.

I wonder what would happen to someone if they set in one of those 180dB vehicles? Like, instant bad hearing loss? vomiting? What?

Instant bed wetting.

I've always heard that if you sit in a vehicle that does mid to high 160s, that it can cause your heart to stop, literally.

Any truth to this?

Massive internal organ failure and rupturing as well as all the capilaries in your skin would burst and you would start bleeding through your skin.

We used to do experiments on rats.

your heart can skip a beat at 150 dB

Are you fvcking serious? About the experiments that is.

200~250 decibels will destroy everything within several miles. 400db is like a hundred times louder than that and the resulting pressure wave would incinerate everything on the planet. it would be a worse pressure wave than if a metior the size of rhode island slammed into the car show.
the kid is a liar. and an idiot. please show him this thread, id like to hear his reply.

not to mention "Theoretical limit for undistorted sound at 1 atmosphere environmental pressure is 191 dB"... so 400db would have to be in space lol. he has a space ship car obviously.

that cant be proven!, its all a myth!!

in like 50 years that will be bullshit anyway lol

your heart can skip a beat at 150 dB

so because i have a heart murmur my heart is beating faster than 150dbzzzz? DAyumm

Yup, It's funny that a few of us dB Draggers were contacted by the military because they wanted to study the effects of high SPL on the human body.

At a big dB drag show back in 2001 or 2002, someone put a hamster in their extreme car that was doing 170s. It ripped the hamster apart.

this thread is actually pretty interesting.
