Just like Acclivity did for the race-cars I calculated the speed of the geese, based on the doppler-shift in the frequencies of the quaak before and after the pass-by:
Frequency of approaching wave = 809.7 Hz Frequency of receeding wave = 767.0 Hz Speed of geese = 340 * ((809.7 - 767.0) / (809.7 + 767.0)) = 9.207 m/s = 33 kph.

great! i'll maybe use this in a short movie that i'm the sound designer of.
haha awesome Bram, and nice recording Acclivity

So, the geese were -perhaps- flying at 33kmph
