Well, suffice to say I'm not sleeping in a server room. The human brain is
actually quite good at filtering out continuous white noise, which is why
sufferers of tinnitus are sometimes given an apartus to try and replicate the
ringing they hear in their ears - often the brain will recognise it is coming
from an external source and block it out.

If you have links to more information about hearing loss caused by continuous
low pitch, low volume sounds, then I'd be happy to read them. I am somewhat
skeptical at the impact of this at the levels present in my room, however.
