Headsets - Volume Settings

I'm just curious with the volume settings. Okay is there a way to set the volume settings for headset wearers out there to reflect that you are sitting inside the airplane with your headset on. I've seen some noise cancelling headphones out there (not sure if they have headsets like that aswell?). Back to the topic. Given the engine distance from the cockpit and the amount of 'Soundproofing' a cockpit could already have. What would be the appropriate volume settings in the sim to reflect this? Would there be different settings for each aircraft type? Lastly is there a way to make these settings part of the aircraft/sound config file?This could be something to be added to the next version. A headset selection for volume control (online flight and voice ATC progressing as it is)No doubt about it...Ronson2k
