db level in cabin at 70mph on concrete pavement?

Yes there are a lot of variables in acoustics. I have taken graduate engineering acoustics classes and spent many years tuning sound systems and it drives me nuts sometimes to make sure I am working in a consistent manner to get good measurements.
So we can have a consistent discussion, I recommended the use of the dBA scale, a specific averaging measurement technique, and the measurement phone application. Also important to note is the speed, road conditions, and tire type. Others are free to comment but I get very consistent results with these techniques, maybe 1-2 dbA variation for a certain type of road at a certain speed..
I have spent a lot of time on sound reduction in my car so I don't have drone and tire noise and would love to hear other people's measurements and experiences. It would be preferred if they can relate specific measurement techniques and conditions rather than anecdotal statements. I hate tire noise and am pleased with the results I achieved and happy to share with the forum on how to make this happen.
