Yes and yes. (well 12.7, 20, 25,30, 35, 76.2, 90,105, 155, 203, all kinds of morters and tracked and wheeled ) From my experiance you are incorrect. Sound plays a vital role in locating and identifying the enemy on the battle field. The wide open ranges of AH somewhat curtail the real role that sound plays especially at night, but a better implementation would definalty add to the game.
Your assumption that a given vehicle would be buttoned up and have the main armemment firing and engine running at the time when hearing an m3 going 60mph on the other side of a rise became critical is just that an assumption..
Yes the battle field sounds might mask the critical sound at the critical time. But a good sound system would do that too.
I just think your initial thread is right on the mark but your response about the sounds was not. Improving the sound system to the point where if there was a critical sound that your crew could hear to stop a sneak attack then you hear it and can make the leap to interpretation and action that would only improve the game...
You seem to be saying that it would not.
Is it worth while putting 60% of our cpus to 3d sound processing...no. But it is worth improving...
