Do you calibrate microphone for each recording? I wonder if they are comparable between different cars you record. I am trying to find out which one is the quietest, CR-V, Soernto, SantaFe or some other from similar car class.
I’m not sure if I’m of help but I’ll just say that the video is from Korea where they use KPH so that’s bout 70 mph I’m guessing. The road conditions are also different and etc but from the looks from it the cabin seems relatively quiet on highway speeds
