BMW is not the only car manufacturer to consider acoustics and sound in the design of their cars. But this is the one of the few videos that feature them, and show what they consider in the design of the sounds. Very cool stuff. I wish I could work in this area of acoustics. Not that I don’t like what I do now, but at least it looks a bit more fun.
Looks like they use some form of active noise cancellation in the car to reduce (or even out) the effects of road noise throughout the interior using the speakers in the car. I wonder how much ‘engine noise’ they also pump in through the speakers.
