Here is a short video of a sound meter measuring the noise level in the MME at 72 MPH. This part of the video shows the noise level to be 66.X, but the longer portion shows the level more in the 67-68 dBA range.
Very impressive. Just for something to compare this to, though the Model Y doesn't necessarily set a high bar for noise, this video has the measured level in that vehicle more in the 75+ dB range when going 70 MPH. You can see at 6:00 the noise is being measured more at 79 dB. So it might be that the MME has 10X less noise. (Again for context the MY is apparently quieter than the M3). I wouldn't go overboard with the comparison because at the least you'd want to test both vehicles on the same road on the same day at about the same time using the same sound meter (mine is calibrated). But still ....
The MME is just very quiet. That was immediately apparent from my standard "voice test". That consisted of seeing how fast you can go and still have a conversation without raising your voice. In the Bolt I need to start projecting when it hits 68 MPH. I didn't need to do this when the MME was going 80 MPH. Big difference.
