Try 15750Hz, the standard video frequency...Yes, I can hear it (age 34) and
it drives me crazy.  Some advanced high resolution monitors/video generators
operate at higher frequencies, up to around 35KHz, where you will neither be
bothered, nor hear.  You will also note that many of the switching power
supplies being incorporated into mondern computer equipment oscillate in the
15KHz to 20KHz range.  

Psychoacoustic studies have shown that frequencies right around 19KHz are real
good at stimulating an "irratibility" factor in humans, and at high enough
intensities will actually drive people to violence.
