Welcome! Hope you end up part of the club, you will love it, of course.
Sorry, but I simply don't understand why anyone would want to take something designed to be fast, smooth, efficient, and quiet (they all go together well) and make it loud. It would be nice if it were THAT quiet as you describe, but it is not.... if you can't hear the bike at all during moderate acceleration over wind noise then you need a better helmet or something! Perhaps you don't even have a "real" helmet??
