I'm now a full 3 weeks into my Volt ownership, and unfortunately I'm not getting used to this sound. Not at all. In fact, I'm starting to think that this is the single biggest flaw with this car. I was originally very excited about the near-silent operation of an EV, but this noise is almost (but not completely) negating the sound benefits over an ICE car.
My 29 year old ears hear it almost all the time at moderate speeds when accelerating/decelerating. The only time I don't hear it is if I'm going over ~45mph or if I have music playing fairly loudly. Talk radio doesn't do any good for drowning out the noise at any reasonable volume.

I don't think there's a human being alive on earth that could enjoy this particular sound. For me, it's like a very quiet, higher-pitched version of this: http://www.youtube.com/watch?v=0cVlTeIATBs

I'm very curious if there are any engineering tools that could effectively reduce or eliminate this noise from the cabin. I was thinking about an active noise-cancelling system. But if the source of the noise isn't small (i.e., a rather large inverter), I'm not sure if this approach would be effective(?). So maybe more/better sound insulation would be the way to go(?). Or maybe the inverter itself could be modified/tuned to reduce the decibel level(?).
