Oh my goodness, that is correct.
The formula for active SPL at 3 feet for 1 Watt electrical power as a function of the number of actives then becomes:
SPL = 126 + 10*log(n)
Solving for n at 277dB, I get 1260E12. That is 1260 trillion actives. Each one needs 4.1 peak kW for a total of 5.2 quintillion Watts. That's one order of magnitude more than all the power produced last year.
Yup - I stopped at 276 dB because it was 150 dB above the 126 dB ... which is 1000 trillion actives. That last dB needs another 260 trillion actives.
As stated earlier, Ian is gonna need a bigger factory!
That being said - it would be cool if 51 actives could have done this. We could have rebooted the Austin Power movies ...
