I have provided direct experimental measurements of dynamic Doppler
shift. I have also provided a reference to the analysis of
instantaneous dynamic Doppler shift that is given in a classical
textbook on Acoustics by a well respected and reputable author. It is
time for Bob Cain and his equally mindless followers to accept reality
and to acknowledge defeat. While the senseless debate over the
existence of dynamic Doppler shift will undoubtedly continue among the
audio illiterates who prefer to deny reality rather than accept
experimental proof and/or who are incapable of understanding the
applicable math, from a purely scientific perspective, the issue is
settled and the debate is over.
