Now if each random process is also zero-mean (which would be
true for an acoustic signal), then the uncorrelated total power is

P_T = 3 * P,

or about 4.77 dB above P.

Thanks for the math, but I got the same answer simply by assuming they were
uncorrelated sounds and adding them. Three times the power is slightly less
than 5dB.
