background: I had a model 3 for a couple of years and now have a Y ( no longer have the 3). The 3s are insanely quiet. The Y is ok but has a whistle at certain cruising speeds (90-100km/h).

But when they are supercharging they are both ridiculously loud. Like having AC on full bore. Also starting a charge makes the most bangs and pops, regardless of the charger type.

I just finished a 2000km drive and slept in the back on a sleeping mat. Sometimes I parked right next to the highway where trucks were flying past. It was almost silent inside, they really are well insulated from external noise.

I think maybe you just got lucky. My first Model 3 was sort of quiet (just wind noise, Model 3s and Ys are quite loud compared to other similar cars). My current model 3 (a 2023 model) has a whistle at highway speeds that I haven't been able to isolate. Along with a fluttering sound, which may be related, and sounds like it's coming from the passenger side mirror area.

The next Model 3 ("Highland") uses laminated glass in the rear windows, whereas the current one just uses it for the front. Should be the quietest yet.

I've seen a Model 3 with very similar sounds coming from the passenger side mirror. There was a loose piece sticking out of the bottom, pushing it back in fixed it.
