I did.
Actually on two different X's. One was a little quieter than the other.
I used a phone app. All you golden eared audiophiles, please don't hate. If the device has a modern microphone and the app can do a frequency weighted profile it's probably enough to get you *something* useful, certainly enough to do a simple A vs B test.
NIOSH (a unit of the United States Center for Disease Control) makes a free phone app that measures noise (using "Profile A" by default).
My most recent results with this app were very much in line with what these people (a German site?) found:
Any time you do this I fully realize it mostly matters what speed you are driving and what kind of road surface you are driving on, next most important is probably tires, then all the other highly variable stuff like wind and rain and other cars nearby and HVAC (and radio!) and so on, but anyway I'm trying to be intelligent about averaging multiple readings, discarding outliers, trying to characterize a *range* of different readings, not just doing a single snapshot and assuming it applies to anything beyond that moment.
Anyway if you wanted to know some numbers to start the conversation, my old 2016 X 75D with newish Nokian G4 tires traveled a normal-condition stretch of I-5 at 75 mph registering readings from 54 to 62 and averaging around 59dB
My 2016 P90D with oldish Nokian G3 tires did the same stretch of road at the same speed on the same day registering anywhere from 58 to 64 and averaged 62dB
Don't know about you but the difference between 59 and 62 seemed noticeable.
For a car with no engine noise, 60 seems fairly loud. I did see a thread about newer X's supposedly being quieter. I've also seen remarks about how the foam lined OEM tires don't really do a lot. This seems like an oppportunity for Tesla.
Anyway, have you ever (safely) looked at a sound meter while driving your X?
