he is correct......The deep low humming that comes from the engines of the L1011 Tristar on startup is loud and I remember hearing a TWA L1011 start up in St. Louis and at first didnt realize at first that this low humming was coming from the plane....It was loud enuff to rattle the windows...I actually tape recorded that sound....I think it has something to do with the starter's mechanisms in the engiens, prolly from bleed air....
Rolls Royce engines always make lots of noise and lost of smoke...Ever watch an L1011 start up in the winter???? The starters on the RR
Spey on the BAC One Eleven sound like an air-raide siren....Conways on the VC
-10 are supposed to sound unusual too!!!

you spend waaaaay to much time listening to engines!
I guess you can say that I ALSO listen too much to engine sounds too..no need to ridicule anyone over it....get a clue buddy!!!! I could go into a whole description of how different engines and props make certain sounds on different planes and how some people have keen enuff hearing to recognise a plane by the sound it makes....
