I find sometimes the whine is there... you (and others like you) just lack the high frequency hearing to perceive it.
I’ve walked into plenty of places and complained about many high pitched whine noises over the years, and more often than not, I get a puzzled look followed by some variation of “what noise?”
And to preempt the obvious possibility I was merely hearing things or have tinnitus. Yes I’ve had my hearing checked, and I’ve also, on a couple of particularly egregious occasions, used sound measuring equipment that in one case validated that there was in fact a loud intermittent, nearly inaudible noise fluctuating between 80 and 85 decibels whenever it was occurring, that apparently no one else in the office noticed.
