The main commercial interests in subjective audio noise reduction,
particularly for speech, are probably the hearing aid industry.
It is subjective because noise reduction only really removes noise that
isn't interfering. That is still useful, as whilst the human brain can
also do that, it gets tired in the process.

This would be tough since the world of RFI sources is huge. It would
take some real effort to quantify the world of noise sources and their
signatures and then find some algorithms to deal with them. Impossible?
The world of big data isn't so big any more. Such an catalog might be
doable. Algorithms are another issue. My hope is that NR/NB could be
made adaptive to recognize the signature(s) and generate appropriate
algorithms on the fly.
There are a lot of smart people out there who could perhaps address
these issues. Unfortunately commercial interests have to see some
payoff. They haven't as of yet. The fact that AM broadcasters are
being burned by RFI and becoming proactive is a plus.
