Krakatoa is supposed to have generated about 310dB, so your 629dB would probably require a new Big Bang.
I don't know how they arrived at that figure? AFAIK the loudest sound you can have is about 194dB which is one Bar and so the 'negative' part is a vacuum.
But then there are "blast waves" that move faster than sound?
There used to be a guy in HFNews called Rex Baldock that wrote very interesting pieces about things like this...seems nobody cares much about science any more?
If we take the average atmospheric pressure as 1 Bar, that's equivalent to 194dB SPL.
So a sound wave larger than 194dB SPL will reach full vacuum on the negative (rarefaction) peaks and essentially clip.
However, the positive peaks can continue to compress the air and 310dB SPL is going to create a half-wave rectified signal the equivalent of a staggering 632,455 Bar (or over 9 million PSI) of pressure....which is going to do a lot of damage.
If my maths is right, thats the roughly the same pressure as being 4000 miles under the sea!!! (The deepest ocean trench is only about 7 miles or 11km, and about 1,086 bar of pressure).

Oh I’ve paid those dB off many times over in the loud and perhaps not proper language I have used while on hold with the banks!
I sure hope they can’t record what people are saying while on hold . . . .
Also
so kind of you’se not to laugh that I put D flat instead of dB

I seem to remember 'Disaster Area' the loudest rock band in the Galaxy in The Hitch Hickers Guide to the Universe. Could this be it?
