Hello!
I've been looking in modern physics textbooks for a reference to
the acoustic transverse Doppler effect.

In other words, the Doppler shift that you'd expect to hear if the
source was stationary wrt the air, and you were moving past at v m/s,
and pointed your rifle mic out at 90 degrees to your direction of
motion ... when you hear a quick burst of signal entering your
directional mic, what sort of frequency shift should it have?

Anyone know of a good reference source that gives the "official"
equation for this shift?



PS: I know what =I= think it ought to be, but I can't find the damned
thing in print.
PPS: If modern physics people don't know about the effect, can I lay a
claim to it? grin
