Low pitch humming like a distant drone, constant low bass humming. At first I thought it was a distant engine, or electric transformer, or factory sounds in the distance... but I have ruled all those sounds out. Other background noises can drown it out i.e. refridgerator, fan, furnace, car going by... but complete silence it is a low humming almost rumble hum in and out. Have tried for months to locate the sound. P.S. it is NOT tinitus. I recently moved to the country, where silence is golden... but not here. I sometimes I 'feel' my eardrums quiver. It is NOT in my own head, I have found a couple other people who can hear it and they say it sounds like a low pitch motor or humming of electrical transformer.... I do not hear it everywhere I go (so I know it's not in my head)... but once I moved here, and heard the distinct sound, I can now pick up the sound in other locations (but not as loud as Wild Rose).

Low humming sound, feeling of vibration in head near ear. Morning and all night. Other sounds can cancel it out. It does not overlay it.. But the humming suddenly breaks if any sound (music)…
