Rather than generate hypotheses that the high frequency noise
1. doesn't exist
2. is some sinister plot to derail EVs in general
3. is a random experience of the "anti-EV" folk
I would propose that Nissan, and the rest of us who are NOT bothered by the noise, appreciate that it does exist. The spectrographic images confirm the presence of a continuing high frequency "feedback" from the Leaf's electric drive system. Based on the comparison to the Chevy Volt, this kind of "electric power feedback noise" does NOT HAVE to be present.
So, this is an appeal for the Nissan Leaf engineers to further review their design work and "tune this out" for 2012 onward. It does the development of real EVs, like the Leaf, no good at all to have design "irritations" built in that would be a turn-off to any prospective, fully hearing enabled potential buyer (not a semi-deaf one like myself).
I am quiet "OK" with using our Leaf on a regular basis, but it is not a "happy time" to watch my wife wince as she suffers this level of auditory input.
