Air-noise in the cocpit

I do not hear simulated air-noise in the cocpit when flying. All that air flying past the window should make some noise -

and it should be increasing with the speed. Does the rain make noise? Does a hailstorm make noise?

in my experience rain and hail do make sound but i can’t remember exact volume slider what it was but your audio output settings effects too e.g headphone simulation or etc from mfs2020 settings

Flying the Mooney M20R, if you start to overspeed you definitely hear the wind whistling. I think it’s the same for all aircraft, at least the GA ones I have flown.

If you want to hear something really cool, take a Savage Cub high up into a storm cloud, and kill the engines, and just listen! The sound design is amazing.
