If the sound source is nearby, sure, that's what I'll hear. If the source is far away, do the waves colliding over the course of a mile before they reach my ear lessen the shift up? | |

Enns | Are you maybe thinking that the Doppler shift is the difference in pitch that you hear between when the ambulance is approaching and when it is moving away from you? The Doppler shift refers to the change in frequency of what you hear compared to the source frequency. In the case of the passing ambulance you notice two different Doppler shifts - on increasing the pitch and then another lowering the pitch. | |
