Here's a good exaample of the SPL from the sonic boom, I really wonder how loud it was.

some quick searching

A sonic boom is the audible component of a shock wave in air. The term is commonly used to refer to the air shocks caused by the supersonic flight of military aircraft or passenger transports such as Concorde (Mach 2.2, no longer flying) and the Space Shuttle (Mach 27). Sonic booms generate enormous amounts of sound energy, sounding much like an explosion; typically the shock front may approach 100 megawatts per square meter, and may exceed 200 decibels.

10 log (100 x 10^(6)/ 10^(-12)) = 200 dB

This may vary slightly depending on the sound energy but 200 dB is considered the normal, this is at the source of course.

Just to make it abit more interesting for you, if it happened at 30,000 feet above, your hear a decibel level of:

30,000 ft = 9146 m (approx)

200 - (20log(9146) + 11) = 109.77 dB

how did the world almost end?

Not a single person died...all of the injuries were from shattered glass (minor cuts) that happened from a sonic boom

Makes the story more interesting.

And the fact more than one person agrees does not make it a circle jerk, it makes it a bukkake scene and you're in the middle ;)

Chick took 3 shots of Jager, and then, pissed in my mouth..

they still say they are investigating the extent of the damages and total injuries, and if there were any deaths

my thoughts exactly.

this would have been amazing to see in person.

If I answered you in a well mannered, informative way, you asked a good question or had a good attitude. If I was an asshole, you asked a stupid question or you had a fucktard attitude... or I was in a bad mood.

they clocked it moving at 30 kilometers per second, which would be 1800 kilometers per minute, or 108,000 kilometers per hour,

Or for us Americans, 67,108 mph

Im sure that was a big boom and made some eardrums explode
