It would be great if the 777 had different sound for different camera views, I know that It is almost impossible to capture different sounds for every view. But I have one area of concern in particular- the wing view. From what is have seen (apart from very few exceptions- the new precision manuals’ 737 )- most aircraft use the same sound that is captured from an external point- it just gets incredibly loud because the view is very close to the engine. Having a sound set that is captured from inside of the plane near the wings will result in a much better experience when fly with the passenger’s pov.

I would be absolutley great if this could be the configuration. E.g. the cockpit sounds with diffrent flap noise and possibly a universal passenger saftey annoucement to fit all airlines.

Unfortunately, it's impossible to make a sound like that.
Here are how sound cones work.
Inside cone angle stands for where you will be able to hear the specific sound (such as whine or groan) while outside cone angle represents where you can't hear this sound.
Second post with more details...

I think you may have misunderstood my point,

My point is that in most other fsx add-on airplanes you will hear the same sound in the wing view to the sound that you would hear while standing outside the aircraft, my argument is that- the experience in terms sound, is somewhat un-realistic because the interior sounds are considerably different to the exterior due to the insulation inside the aircraft.

As a matter of fact- precision manuals development groups’ 737ngx has this sound variance (interior wing view is different to the exterior), which is much more immersive.

in short- the wing view should sound like you are sitting in side the cabin (not like sitting outside on the wing- its way too loud and sharp)
