The other day I experienced the audio #DopplerEffect of a stationary emergency vehicle siren as I #cycled past it. Everyone has experienced a speeding ambulance or police car with its siren going off and its changing pitch as it goes past them but it was interesting to experience it in the alternative frame of reference. Not that I was going all that fast and so I was particularly surprised to notice the pitch go from high to low.
