The thread might be old but the names of the companies supplying the equipment will be fairly consistent. particularly those with quality products. For n/c I use Phillips for silence I use a particular kind of ear plug from the USA that is more expensive.
The key problem is that each person's idea of noise is different. I have had tinnitus for as long as I can remember and that makes my needs different to others.
By the way,
