Noise attenuation
I have read/heard on a number of occasions about having the right mic/ear piece for the helicopter, that there are noise attenuation or other issues of having the right set up for the right helicopter (piston /turbine...)
I'm now brave enough to ask, how does it all work and how do I know if I am buying the right item for the right helicopter?
Will the same mic work across the board in R44/B206/AS350...?
