Listening to 40wpm ARRL code practice files http://www.arrl.org/40-wpm-code-archive with a speaker in my bicycle front basket, I noticed a quarter-tone rise in pitch when a headwind hit my ears. It couldn't be doppler, because if it were I'd soon be listening to the future and it would be a time machine (the cycle counts have to work out). I suspect the low frequency dominated wind noise shifts the perceived peak in the frequency spectrum of the tone upwards. The tone is a sine wave, rather than a modulation. I think with a modulation-pitch there would be no shift. Somebody should verify both. -- rhhardin@mindspring.com On the internet, nobody knows you're a jerk.
