So, no one has responded with any testing comparing a 2019 before "improvements" and 2020 after "improvements". I recognize sound is subjective. One of the frustrations I have with comparative car reviews in magazines like Car and Driver and Motor Trend is that they do not consistently do interior noise testing, even though they often give a NVH score. I understand why they might not report such data for individual car reviews since the road surface has a major impact on interior noise, but for comparison tests they have the cars in the same location and could easily include some dB testing. I recall in the past that reviews often included idle and 60 or 70 mph highway interior noise ratings, but I have not seem them reported much recently. Consumer Reports includes a noise rating, but it is on a 5 point categorical scale and I have not seen any reference to what the scale points translate to on the dB scale. Has anyone seen testing of the Model 3 in any of the car magazine reports? I have not been able to find one. I did see a recent Youtube comparison of the Model 3 and the Model Y, the Y was slightly less noisy in that video.
I could do my own testing (imperfect as it is with testing equipment) and compare some of the cars I am considering, but that is not easy to do during the COVID pandemic when most dealerships are closed. I am coming from a BWW 5 series, which is very quiet, so I may be more sensitive to increased noise compared to others transitioning from cars with interior noise more on par to the Model 3.
