Wind Effects when in Game map says 0 M/S at 0 and 500M

[JG1_Wittmann]

So in game when you try and set up an ambush position  and unbutton your commander  then turn the sound up ( Since in Game sound for Approaching Tanks does not work properly )

you will notice 2 things.   You hear wind in your ear, as if you stuck a seashell next to your head,   the trees are swaying.   Why would you hear wind, and see it's effects on trees when there is none ?     Also,  a suggestion to make in game voices and chat notifications Player select-able so we can turn them off.
