That's a shame. I suppose the question is this:
Is it getting past the screen on the audio cable and in turn being picked up by the audio core, from one of the other wires in the bundle?
If so, will an outer overall screen help? Probably not.
On the other hand, if interference is leaking from the power cores to something else outside of the bundle, then yes, perhaps an overall screen is the answer.
A difficult question to answer without doing the experiment first.
Other thoughts that spring to mind (sorry, you've probably already thought about them):
Where do you think the whistle is coming from? Is that too high for it to be the vibrator? I ask because I have no experience of them, but somehow expected the mechanical ones to run at a lower frequency. I don't know...
I suppose it might be possible to pull the audio cable from the bundle, then you could try spacing it away to see of the interference changes?
Was the noise there before you changed the cable, or is this the first time you've had the set working? If so, it's entirely possible that the cable isn't the problem.
Either way, I'm sure you'll get there
