Since I got my Model 3, I've had a crazy ringing in my ears. Finally I fired up a spectrum analyzer in the car and lo and behold, there's a significant and narrow peak at 19 kHz. After some experimentation I discovered that it's related to the fan, increased fan raises the peak. Pretty sure this is causing the ringing, but I'll turn off the fan for a few days and see what happens.

Can folks check and see if they have the same peak? There's a free spectrum analyzer called spectrum for iOS.

Thanks!

Here's a pic. Seems like it's strongest under the steering wheel, but it's tough to pinpoint using my 'high end' equipment.

I have that also, but it seemed to start after the 21.9 update. Didn't notice it at all on 18.3 (which I had for a few weeks). Almost sounds like the whine of when you have a wall wart when it's charging? (But while driving of course.)

Frankly I now have a harmonic whole driving only after the 21.9 update. I thought it was in my head. Now I think it is new
