It may not be applicable to assign a straight db maximum?
Different aircraft make different frequencies of sound, the psychoacoustal brigade will argue that a large 3d aircraft gnashing its prop at 70db is going to be a lot less offensive then a low blade high speed edf at the same db to the ears of our field neighbours.
