If I am not mistaken, what you are experiencing is commonly called alternator noise. Or the electronic interference your speaker is receiving while your alternator is spooling. (Faster it turns more voltage output = more noise).
Are your speakers stock?? If not and you put a system in your car, try a capacitor, at least a 1.5 farad. That worked for me in the past.
Maybe a voltage stabilizer . . . Hmmm
As far as the Air Bag, go get it checked, and if you are stock say you are experiencing interference in the right front speaker it isn't normal, and they should fix (or at least attempt to). Could be somthing as simple as a ground.
