I measured cabin sound level, in db, using the Sound Meter on Android, was wondering if someone can measure the same and post results here:

At Idle, in D1, foot on brake: 47.2db.
At Idle, in Neutral, with Parking brake on, foot off the brake: 51.0db
At 55mph, in D6, on state route: 65.9db
At 70mph, in D7 on interstate 69.9db

Engine at operating temp, all windows closed, sunroof closed, with shade closed too (I just installed a new sunroof gasket, there was significant wind noise before and its gone now), and AC off.
I think i get lot of wind noise on the windshield. It had cracked and I had it replaced by Safelite repairs; i suspect a cheap windshield, not Genuine Original.

Interesting and happy to contribute. Where was your phone placed and where is the mic on your phone? Need to standardize testing method as well as possible to control variables in our psuedo-scientific experiment.
Phone was clipped to the driver side air vent on the dash. The phone was a Sony Xperia, running the Sound meter app. I think without calibration, we can only compare relative decibel levels for the different settings and speeds.
