round_peg Posted June 12, 2012 Report Share Posted June 12, 2012 I am trying to track down an issue using my Lightspeed 20XL headsets in the CT. When I started flying the CT I dragged these "old" sets out of retirement*. They needed new ear seals but otherwise I saw no reason why they should be any less effective in the CT than they were in a Cessna. Right away I noticed that when climbing at WOT the engine noise I am hearing through the headset when I key up is close to deafening. I feel the need to shout over it. Then the other day I was flying X/C and called ATC for flight following. They could barely copy me. It took several tries, speaking very loudly and slowly, to get radar services. I did not have this issue (at least not reported by ATC) on the return flight. But at cruise RPMs I am getting more engine sound bleeding through to the transmission than I can recall hearing when these sets were used in another airplane. Could it be that these headsets are not "tuned" properly to cancel out the higher RPM noise of the Rotax? My partner in the CT hasn't had this problem, to my knowledge, with his ANR headsets. I am mystified, and I don't want to invest in new ANR headsets if the issue could be elsewhere. *About ten years old -- Lightspeed no longer supports them.
