You hear the 4000Hz music of the ice cream truck driving around your neighborhood on a warm 25⁰C day. You really want ice cream, but your wallet is nowhere to be found. You locate it after a few minutes of frantic searching, and run out to the street, only to see that the truck already passed your house and is moving away from you at 10m/s. The music now does not sound so cheerful. What frequency of music do you hear?
