clarified for which medium the reference intensity is relevant

Fixed the reference pressure of air

That would drop 10${}^{11}$ watts to 10${}^{5}$ watts, and for 1 millisecond that would be 10${}^{2}$ Joules, the same as your value. Thank you for working the problem through clearly! Also I like your linked answer as well | |
