Best NC mic?
What's the best noice cancelling eletret mic for high-
noise, open cockpit operations (Rotax 503 tractor prop 5 feet out in front of windshileded cockpit)? Flightcom has their A7A.1, Sigtronics has their M81-H, and then there's all these others, like M54, M55, M56, M90, M7A, M4, PA-4, PA-9, etc. etc. It's SO confusing since very few of the on-line and print catalog dealers give mic performance specs like freq range, output levels, etc. to make any sort of a comparison. I currently have a Sonetics A9 made for Flightcom with an OregonAero MicMuff and I'm wondering if this is the same mic as what they are calling the A7A.1 with it's advertised distortion free output. My comms are undistorted and audible, but there's still a LOT of screamin' engine coming thru as if the A9 wasn't going a good job at cancelling noise. Yes, it's mounted and pointing the right way on the wire boom. Another flyier in a similar plane has nearly inaudible back ground engine noise from his Sigtronics SE-2 or S-8 headset which I think comes with the M80 or M81H. What are your findings and preferences? |

Dean,
One of the first things I would do is to borrow the other flyer's headset and try it in your aircraft. Sid Dean A.
