where
: emitted frequency
: propagation speed of waves in the medium
: speed of the receiver relative to the medium, added if the receiver is moving towards the source, subtracted if the receiver is moving away from the source
: speed of the source relative to the medium, added if the source is moving away from the receiver, subtracted if the source is moving towards the receiver.
