I hear mine, but it's not as loud as in these videos. Do you guys notice it more if you crank up the AC compared to keeping it at speed 1 or 2?

The compressor in my MB SLK was so loud when the car was idling it sounded like a jet was taking off. As loud, if not louder, as the Tesla.
How can a compressor noise, or any normal noise emanating from a car, be "embarrassing"? This must be the first AC compressor in history that makes someone feel ashamed. That's not the response I had, not by a long shot. I've had my car for over 9 months. The compressor is loud because there is no engine noise masking the compressor. There is nothing abnormal about the noise itself. Cars make noises. So do EVs, for that matter. Just because our cars are electric doesn't mean they will always be silent in every circumstance. Cars make noises.
The first time I heard the AC compressor, I thought "oh hey, that's the AC. Cool." I never assigned a negative emotional value to that noise. It's a normal noise. Just like the vacuum pump coming on when you tap your brake pedal. Or the car making a similar noise while it re-levels itself when you exist. Living in AZ, I'm thankful the Model S has such a powerful AC.
I just leave mine in Range Mode. Even at 85*F here with 95% Humidity, we were freezing within minutes. If I turn range mode off, the Jet Engine prepares for take off.
In summer, does range mode slow the cooling of the battery, and if so, what are the ramifications?
The Roadster shared the A/C between the cabin/battery pack. I didn't think that the Model S did that, but my car seems to go from blowing very cold air to warm, then back to cold. This is with the temp set to LO, and A/C fan speed set to 11. Does anybody else see this? I can't figure out if it's a software bug, or pack cooling taking place.I'm not sure that battery cooling is tied to cabin cooling to a large extent, if at all.
I may choose to drive with the AC off completely even in very hot weather. In theory, that is. That shouldn't compromise battery cooling which must be a largely independent system.
Got a call from Tesla Burlingame about this; I hadn't initiated anything other than post on this thread
Trying to bundle this TSB along with a couple of others (armor plate and defog vent retrofit - for the next winter!) in a single service visit.

That's a good point, but I would have to think that Tesla thought this through. Many people will want or need to use Range Mode for a variety of reasons, but if the battery requires cooling beyond what Range Mode can deliver, the system should accomodate.
In the winter I use range mode a lot, although I try to remember to turn it off at night so I can pre-heat effectively. In summer, I'm thinking it might be like range charging. Do it when you need to, but not otherwise. But I don't know, which is why I asked.

From what I understand the there are three cooling pumps. They are shared by the cabin AC and battery pack. On my S85, one of the three pumps was weak and noisy. It was fine until I used the Supercharger for the first time. It then complained and said to take it to service. The pump was replaced, the message went away, and the noise subsided considerably. Seems like there is a systemic issue but not serious other than the noise. Give them some time...they will get it resolved with software.
I personally gave up on Range Mode in the winter because I found it didn't really make any difference in my range. It is likely because I'm usually driving at least 40 miles at a time. It may be beneficial with shorter trips, however.
