Now, using YOUR proposal, please explain to the gathered

the size of a 747. According to you, if you can superimpose
a second, out-of-phase 747-sized noise source on the
original you're done. So then only place I can put the
correcting source is NEXT to the 747, say at an average
distance of 100 feet, and place the person awaiting the
sonic remedy exactly in between the two.

And how's that working out for you?

Silly eeyore, I said that in /some circumstances/ if there
was one source you could colocate source and corrector.

No, you, in fact, said:

"Such as the entire cabin of a passenger aircraft, "

Which cabin of which passenger aircraft has one source?



The cabin of the passenger aircraft used many error mics and many
cancelling loudspeakers. I very much doubt that I said that it was an
example of a single source, single corrector system. IF I did then I
apologise for misleading you. IF I DID NOT then learn to read.
