I have been wondering what type of noise others get in their cabs when driving, and although we can't have any kind of scientific study, I wonder if we might actually gather some kind of data just to see if it might be possible to tackle noise a bit more. For example, if several of you have quieter levels than what I have, I'd want to know some of what you've done to get it quiet. So here's what I think might give us a baseline.
Download the app NIOSH SLM for your iPhone. You can look at the info to see why I recommend this app. Don't mess with any of the settings, but start looking at the noise levels with the phone in a holder while driving, then report what you find here.
110, 300Tdi, standard exhaust, roof rack, 235/85 BFG KM2s @ 60mph flat with windows up = ~74 dB
