Pre-takeoff checklist
My wonderful wife of 19 years went out and bought me my first ANR headset, a Lightspeed 20-3G. I was so excited about getting an ANR headset that I could hardly wait until the weekend to go and try it out. I tried it at the house and was very impressed with the noise canceling feature. However, actually flying with the headset disappointed me greatly. I have several cheapo headsets as well as a Flightcom 4DLX and a DavidClark H10-20. The Lightspeed headset, without the ANR turned on, was actually the worst sounding headset that I had, even comparing it to the $69 cheapo set. Now, Lightspeed did fit and feal better but sounded terrible. When I turned on the ANR the quality started showing through. It was just a little bit better than the DavidClark. Wondering why this was the case I did a little research and called Sportys technical support. The NRR of the DavidClark and the Flightcom was 24dB but the NRR of the Lightspeed (without ANR on) was only 12-22dB. I asked why the 12-22dB range and was told that it depends on the frequency (low or high). I think the the NRR was closer to the 12dB than the 22dB. With the ANR turned on the Lightspeed clam-to-fame was 22-24dB. Well, the DavidClark and the Flightcom offer 24dB so why is the ANR any better, I asked? They couldn't give me a good answer and just kind of stumbled over the question. I look at it like this, 24dB is 24dB. So how would the ANR be any better than the others that have the same NRR? I certainly could not tell much of any differance! Any input would be greatly appreciated!
