The noise reduction spoken about is a complementary code/decode process
and there´s been a lot of different such processes:

Dolby A
dbx type 1
Burwen
Dolby SR
Telefunken Telcom c4

The difficulty is in having the right decode box and the knowledge to
adjust it correctly together with knowledege what the relevant NR "tone"
sounds like on tapes where the NR is not identified or even lacking that
the ability to recognize what Dolby "A" coding sounds like even though
the box doesn´t say a thing that the tape used any noise reducing
techniques at all.

I agree that these skills will in a generation be lost and getting the
best out of these tapes might be an impossibility in the distant future.
