So for drone around 110hz-112hz (around my setup), you get to 2.5 to 2.4 ft, or 29-30".

So...to get the frequencies of your droning, you put a microphone to your exhaust and ran it through a spectrum analyzer (i.e. Audacity if you're not in a lab...haha) to get the peak frequencies? Out of curiosity, did you run any filters on the output, or was it all raw? How clean was the data?

Nothing serious, just piqued my curiosity. I like reading stuff like this.
