Ask the Mountie

Are you ever subjected to the "doppler effect" while horse-riding on duty?

Dear mr. mountie

Are you ever subjected to the “doppler effect” while horse-riding on duty?


Dear Singe

For those who are not aware, the Doppler effect, named after the mathematician Christian Doppler, is the apparent change in frequency of a sound as perceived by an observer moving relative to the source of the sound.

Christian Doppler was destined to become a stonemason, like his father, but he was a weakling more suited to academic pursuits, hence, he devoted his life to mathematics until his untimely death from lung disease in the beautiful surroundings of Venice.

To get back to your question, the most appearant evidence of the doppler effect whilst horse-riding on duty would be when engaged in high-speed (gallop) pursuits of Ice-Cream vans, since (as I’m sure you’re aware) the Ice-Cream Van jingles start automatically when the van exceeds 23 mph. Such pursuits does on average result in some distortion of the frequency of said jingle.
