Apaches had whisper mode in 1982.......why this thread? I saw a demo in 1982 at a secret location.
The one i saw, could not be heard until it was less than 200 meters away, and that was in 1982

You seem to be very good at linking to articles that you know nothing about. Not to mention naming companies. We don't use Sony Sound Forge nor Avid Pro Tools in the govt. Sorry.
Phase cancellation doesn't occur in the atmosphere like you are claiming. Can you imagine the type of transducer that would be required to accurately noise-cancel a helicopter blade cycling at 200+mps in a ever-changing acoustic environment like your Bose headphones or BMW? If so, show me where it lives on the the AH-64. Pictures.
You're living in a mixing and editing world and you'e got no experience in aeronautic sonic suppression. Audio engineers are not engineers, I'm sorry.
