While complaining about noise; both of my Tesla's and all the others I have driven have high apparent wind and road noise. Honestly I think that is mostly due to the absence of engine and transmission noises but it still is a source of constant frustration.
From days when I operated aircraft I recall active noise cancellation (ANC) for the entire airplane created a blissfully quiet environment from a noisy and obnoxious base case. I think I recall that having been done in some cars. Were that to be available for Tesla Model 3 I would rush to buy. For those of you who do have offensive squeaks and rattles, active noise cancellation isolates the problem instantly. In any event it did so for an offensive but undiagnosable noise in a King Air I owned; post ANC the problem was obvious and easy to fix (lack of proper lubricant for rudder controls). In another case in another aircraft one exhaust outlet flange had broken.
Even though I have zero experience with Tesla odd noises I have had several others in cars. Porsche: suspension bushings; Mercedes: air suspension pump; BMW: exhaust pipe mount failure.
If those are indicative of the types of things that make some odd hard to find noises it seems to me careful diagnosis is essential. I'm sure they are rarely serious, but all the ones I remember in my own life were. Anyway:

@StealthP3D :
And what about my $99 suggestion to track them down yourself with the six microphone array? Yes, that shouldn't be necessary but how much is your sanity worth?
It is not easy to diagnose strange noises. Anything one can do to identify, clarify and amplify the odd noise increase the probability of finding it and solving the problem. We all want the service people to know, find and cure the problem. If the problem is common service people usually know, as in door seals, dash attachments, wheel bearings/bushings. If unusual, service people need all the help they can get.
I recognize that my attitude towards such problems is probably influenced by my habitual early adopter behavior plus my habit of being in places where service competence is famously inadequate.
