I'm surprised no one has suggested this: Model 3 Noise Reduction Kit
It's basically a rubber band that fits into the gaps around the middle section of roof glass over the driver and front passenger. I've seen claims of a 5 db reduction in interior noise. I didn't notice it so much, but my hearing is pretty bad after being in jet airplanes for the past 40 years (measured noise level of 80 [+/-2] db for 15 hours takes a toll!), but my wife noticed it the first time she rode in the car post installation.
