It's a very old and honourable automotive acronym, but a bit odd, since we can measure noise, and vibration, but not harshness.
There is a psychoacoustic measure called harshness but it doesn't correlate with 'real world' everyday noises that would be described as harsh

Tell the "old guard" to change "harshness" to HANDLING.
It would make more sense to the modern automobiles being produced worldwide. Just think of the neat testing you could do.
On that subject, how is ya'lls new chassis coming along. Never see anything on the telly??? Our new Lincoln LS is great @ 10,000 miles (the Continental tires are just so-so).

As to current progress: I'd lose my job if I told you and 'they' found out. Honest. You might want to check out some spy stuff at the Nurburgring published last month or this month.
You won't see our car in the US media, unless they think it's a Jag, which is what happened with the current model!
The only tyre manufacturer I've ever come across with a believable scientific/engineering approach is Michelin. Other people like Yokohama make nicer street stickies, but for an all round tyre I buy Michelins.

RE: NVH in automobiles
In at least one US manufacturer, the "H" has been changed from "harshness" to "handling". Somebody a few years back had the same thought as you!
and Greg--I've gotten the same impression as you from Michelin. Unfortunately for the rest of us, they are (wisely) very limited on just what they will share with others. They are acknowledged by people who know more than me about the subject as being the "best" in the actual "numbers" engineering approach (as opposed to "my butt likes this one better").

I would add some provisos to all this. Tyres ain't tyres. Local plants may supply you with a tyre that is called a model XYZA, which got rave reviews on another continent, but it may just be an old tyre carcase with the new tread, in the old compound, or it may be something completely different. Also the rights to some manufacturers names are held by other companies, in some countries. Also (3) there's a nice market in second hand assembly plant, so the tyre you buy from a third world plant is probably built on a one generation old assembly line, even if it is a premium brand.

Oh, and please don't ask why I would want ice tyres for a Miata.
