I use an app on my phone called Decibel X that measures noise level in dB. A quiet home is in the 40's.
I have a Tech AWD.
Engine started but car not moving -- upper 60's to 70's.
Smooth roads -- 70's to low 80's
Bad roads and highway speeds -- low 90's
FWIW, the quietest cars are in the mid 60's at highway speed, so the RDX is about 1000x louder than those.
