Several months ago I started using Clarity Aloft Headsets. Prior to these I had been using Peltor ANR headsets. Once I started using the C/A I started hearing an odd noise from the cowling area. I only hear the noise when I cut the power and start a descent. If while I am hearing this noise that I will describe as a grumble, I add power, the noise will disappear. Also, I have noticed if I hit some turbulence, the noise will disappear, but only momentarily. The power setting that I hear this noise has to be 5k or lower, but as I say, it must be in a descent.
My guess is that the Peltor's were better at attenuating than the C/A's. I flew a few weeks ago with a Peltor and did not hear the noise which tells me the noise has been there all along. Does anyone else experience this? Gearbox? Normal (Ihope)? Thanks in advance.
