fspassengerX 747-400 LOUD COCKPIT

[Doc3511]

my default 747-400 cockpit is normal but when i open the FSpassenger it sounds like the engines are inside the cockpit.
Its not sarcasm it really sounds like that .
but those ENGINE sounds are definetly NOT from FSX so my question is where are those sounds located in Fspassenger.
i couldnt find them in the sound folder inside fspax and i couldnt find them in the sound folder from FSX
are there any other sound folder fspassenger installs?
I dont change cameras and i dont open the map and its not the aircond sound...
it just starts when fspassenger is executed and stops when i abort the flight and end fspassenger.
i am looking for those engine sounds everywhere but cant find them im really sure they came with fspassenger because they are different
from the default sound

it really surprises me becouse it only happens with this plane and i love it and since i payed for this i d like some help.

FSPASSENGER ROCKS!!!!

Thank you very much for your help Whiskey Zulu.

The sound you are hearing in the default 744 is most likely the airconditioning system that comes with FSPX; you can adjust the volume of this and
other sound files in the company options page prior to starting a flight.
