Road noise wouldn't come through the door panels for the most part, and wind noise would be down to the aerodynamics of the mirrors and door pillars, etc. - more of a design issue I'd say. I'm guessing the bottom pic shows soundproofing felt on a Merc door? (NB, felt only deals with certain frequencies). Can't really see what soundproofing materials are present inside the BMW door
