Hi Again, I found a free iPod app to make sine wave tones that you can compare to the hum. Its called FreqGen http://itunes.apple.com/us/app/freqgen/id325832805?mt=8 Using this app last night on my iPod touch gen 1 and os v 3 and the Apple ear buds I was able to mimic the hum. In my case the frequency is a sine wave at 58 Hz. The app is very easy to use to match the frequency with what you hear.
Its interesting to note that the hum does not effect normal hearing, so its not replacing hearing but concurrent with it. Also moving the head side to side makes the hum go away for an instant but this does not happen with the sound coming from the ear bud. So it makes sense that the hum is caused by some stimulus of the inner ear hairs and fast movement of the head may slosh the fluid in the inner ear and either override the hum or stop the hairs from being stimulated. Since my hum is very close to the USA line frequency of 60 Hz it gives credence to the effect being caused by the power grids interacting with the earths natural resonance. Not sure if this is reproducible, but bringing my head close to a Staco 110 volt AC power Variable Transformer also called a Variac, seems to reduce the hum or at least overpower hearing it. Will play more with that and let you know. I have two variac's close together in a room to control heating pads for my small pets. I am sure they put out a huge EMF. They hum but are not the source of my hum heard as unplugging them has no effect. Might be possible to use them to block or constructively interfere with the so called gravity waves causing the hum?
