You've got the clue in your question:
Noise is measured at point of use....your ears. So generating the opposite signal is fairly easy for modern digital circuitry.
Now, where do you measure the RF to generate the opposite signal?
Unclestu would have you address RF at the design stage of equipment to prevent internal mix-ups while for external, coupled RF? Maybe Mr. 6bq5 has the right answer, which would be on a case by case basis. Though the point of use approach using chokes may also work, though the upstream stuff would still be a potential problem.
Maybe a faraday cage for the house...fed by an iso transformer the size of a Buick? Than, use gear, not invented yet, which passes the signal between stages using optical means so RF can't piggyback!
Too many paths for RF to have a single, global solution.
