Loudest Sound Ever?


I really like this guy's YouTube channel and I thought several (maybe a few?) of
you guys would enjoy wasting(?) six minutes...

Actually does a good job of quickly explaining SPL. 
Its 10 o'clock...do you know what your SPL is?

@tomic601 I was in the Marine Corps in the field in NC on a base that had a steam catapult for practicing prior to going hot on a boat.
We were carrier capable but not assigned to a carrier.

Me and couple of buddies are walking in an open space to get to the catapult and an F-4 comes up on us from behind at just over 100 ft and
lights the burners at the same time. Seriously knocked us to our knees.
That was probably the loudest thing I ever heard and I had "ears" on.

      I'd have thought the Big Bang, but: how could there have been a big, "Bang" in a vacuum?

     The loudest sound in human History was (officially) the third Krakatoa explosion/eruption.

               https://allthatsinteresting.com/krakatoa-eruption

                                 Clocked in at 310 dB

                  Energy equivalent to 200 megatons of TNT.
@rodman99999   I thought the same...how could there be a "bang" if there was no medium for the sound to travel through.

As well as the old saw "If a tree falls in the woods..........etcetera"

The loudest possible sound in air is 194dB.  Anything more energetic stops producing sound and becomes a shockwave.
