Imagine you are waiting for a train to pass at a railroad crossing. Will the train whistle have a higher pitch as the train approaches you or after it has passed you by?

THE DOPPLER EFFECT. Anyways, it would have a higher whistle as it approaches you, when it gets to you it only gets quieter because it leaves after. Think of a motorcycle going by, its loud coming to you then as it passes it gets quieter.
