Maybe someone might want to tackle this. Would 703 or rockwool be of any help to quite down cars from highway noise? Tires on the pavement, wind, etc.
There are so many products available that are expensive and supposedly barely do the job.
Also, do you think carpet padding would work? Alot of cars I've worked on have something similar for insulation here and there.
The only problem is I've noticed on some cars they design their door frames around limiting resonating noise so that could also be a factor in deciding how to dampen/insulate the door.
Any views on that would be cool.
