Maybe more than you really want to know but overall sound pressure level (OASPL) scaling really strongly with the Mach number of the exhaust. Something like M^8 for subsonic jets down to M^3 to supersonic jets, I think it gets even worse with high temperature jet cores ( NASA Reference)
With that kind of scaling the amount of literal power in just the noise itself is scary.
