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?

      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.

                                 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.
