Saw this exchange on the Tape Op MB earlier today and thought it was interesting enough to share. Looks like we have a new goal for the Loudness Wars, gents.

i am not smart enough to accept that as an answer.
i mean seriously, is it actually not possible to have a sound louder than 194db? if the earth exploded, we'd only get 194?"
farview said: "It has to do with how much you can compress air. There is a limit.
BTW, sound pressure doubles every 6db. There is a giant difference between 140db spl and 194db spl. Remember 146db is twice as loud as 140db. 152db is four times louder than 140db.
194db is 1024 times louder than 140db (the threshold of pain)
If the earth exploded, it would only make noise for the split second before the atmosphere dissipated. Without the atmosphere, there is no sound."

i wonder if you could compress the air into liquid at higher SPL? man, science is sweet when you don't know anything! where's my jetpack, anyway?

According to this site, a volcano can manage 320 db:

My favorite is:
"282 (N)NUCLEAR BOMB, 57 MEGATONS HYDROGEN LARGEST EVER DETONATED, 1961
SHOCK WAVES CIRCLED THE EARTH 3 TIMES, FIRST ORBIT TOOK 36 HR 27 MIN. -REF.2."

The explosions were so violent that they were heard 2,200 statute miles (3,500 km) away in Australia and the island of Rodrigues near Mauritius, 4,800 km away; the sound of Krakatoa's destruction is believed to be the loudest sound in recorded history, reaching levels of 180 dBSPL 100 miles (160 km) away.[3] Ash was propelled to a height of 50 miles (80 km).
I saw a documentary about 18 months ago that said the resulting sound wave circled the globe 5 times

Might want to turn it down before you get to the 200 range:
"202-198 (P) HUMAN DEATH FROM SOUND (SHOCK) WAVE ALONE. DEATH FROM: SCHRAPNEL AT ANY LEVEL ABOVE 165 DB IS LIKELY AND BEING THROWN (10 FEET PER SECOND) ABOVE 180 DB -REF.2."

So there's no sound underwater?
What about sound in solid rock... do you think seismology work by magic gnomes?
