Today, I got my S tinted (all windows, even the front windshield, but no pano roof). As I was marveling at the suddenly comfortable environs inside when outside temps reached 86F, I thought I heard the radio louder and clearer. Then, I noticed that it wasn't the radio, but the car. Somehow, tinting with 3M crystalline, which is supposed to be thicker than regular film, and supposedly made of lots and lots of individual layers of film pressed together to make a single sheet, seems to dampen the higher frequency noise.
Velo, feel free to jump in with your thoughts on this.
This is, of course, empirical. I am actually kinda picky and sensitive to road noise, but not to the extent of say, Blubrd who ranted in his thread about the net rigor noise levels in the S. I feel, after 3 more test drives today over familiar roads I travel on every day, that the S has become quieter, may be by as much as 20% or so.
Any others who feel tinting has dampened the road noise? Anyone willing to do tests (before/after)? ;-) I was too lazy to do it.
