I'll do some testing next week once I get it all wrapped up as I have readings from before on highway 1 at 100 and 120kph. I did take some readings today and in the city I'm down about 4-5 dbs at 60kph. I used to be around 63-64dbs on average roads and now I'm seeing 58-59dbs on similar roads. This is using an iPhone and the NOISH app (National Occupational Health and Safety).
The biggest diff is with cheaper cars, particularly those that don't have any sound insulation like Mazdas, Toyotas and Hondas. Much less impact with a Lexus or Buick. My RDX splits the difference - there's some sound deadening in place already and some semi-thick carpet but no acoustic glass or a plush ride with soft bushings.
