I am a little confused at the use of sound files which only operate on 4 engines for the B-52: either each pylon-mounted pair has been modelled as one engine with its appropriate sound levels, or the sound level for each engine individually is not actually modelled.

Also, if I wished to use an alternative sound set which, say, had originally been developed for a four-engined aircraft, how would I modify this set to account for 8 engines in terms of realistic sound levels?

Footnote to the above:

I have been experimenting with a JT3D sound set from TSS originally produced for a Boeing 707, and simply doubled the values associated with volume in the vparams entries in the sound.cfg file (to accommodate the sound appropriate to 8 engines). The result is awesome! Also, it would appear from the original Microsoft ESP for the sound configuration files that only 4 engines are permitted in FSX, hence each 'engine' has to represent the paired engines on each of the four pylons.
