Tesla Model 3 road noise reduction

I continue to explore ideas to improve my Tesla.
I've designed and built custom seats. Came up with a window wind noise approach.
Now I'm working on road noise. This is caused by the tires on the road, especially rough asphalt.
The work I did in the video did seem to help.
But it did not stop the higher frequency sounds that seem to be getting in the side doors and side windows. Next I will be doing more work with doors and windows to reduce tire road noise. I saw someone somewhere mention the noise reverberates through the rocker panels and gets into the doors and windows. That will be another project and seems involved. What I did to dampen vibrations in the trunk and wheel wells was already involved, exhausting, and somewhat difficult to do.

Although I have no scientific measurements.
I believe the work did cut down the lower frequencies and body vibrations.
But it's not enough for me. I'll continue the quest.

I also believe trying to absorb sounds with more expensive sound materials would not be that fruitful. Again, I think we are getting noises from tires on the road, and it becomes airborne, then finds a way into the car. I'll be trying to engineer approaches for that.
