Yes I can hear it. I remember when the washing machine was making an annoying noise, similar to that (something like the bearing was going), and my mum didn't really believe me when I kept moaning about the noise as she couldn't hear it.
Eventually the noise got to a lower pitch, then she realised there was a noise there.
If I'm around a constant whine-type noise, most of the time I end up filtering it out. I'm pretty good at filtering out constant noise, so the noises don't tend to bother me, unless it's of particular frequencies (at the top range of my hearing, or there is a pretty high one lower down that annoys me a lot).
At uni I used to be able to easily fall asleep despite the noise of the fan in my computer at the time, as I would just stop hearing the noise after a short amount of time. Irritated the heck outta my then-bf if I ever left it on when he was there (couldn't tune out the noise)
