That would be on the ground. As in the Noise Levels established by the manufacture in compliance with FAR Part 36 and the ICAO Annex 16 Chapter 3. For example, for the aircraft I fly, the take-off noise level at its maximum take-off weight is 81.7 EPNdB. I'm just trying to compare it to other aircraft which are allowed an early departure turn at a certain airport based on the noise level they were certified to.
I don't have anything to compare the cockpit noise level to if you had those figures. I just know its quieter than the last type I flew but, according to the other guys I fly with, not as quiet as some.
