Re: humming in my ear
It's tinnitus. I too experience tinnitus when I'm in bed. I only first noticed my tinnitus when I was around 16 years old. I am profoundly deaf and did not know what it was. My tinnitus comes in a form of droning or beeping
Tinnitus can be perceived in one or both ears or in the head. It is usually described as a ringing noise, but in some patients it takes the form of a high pitched whining, buzzing, hissing, screaming, humming, tinging or whistling sound, or as ticking, clicking, roaring, "crickets" or "tree frogs" or "locusts," tunes, songs, beeping, or even a pure steady tone like heard in a hearing test. It has also been described as a "wooshing" sound, as of wind or waves. Tinnitus can be intermittent or it can be continuous in which case it can be the cause of great distress. In some individuals, the intensity of tinnitus can be changed by shoulder, head, tongue, jaw, or eye movements.
Most people with tinnitus have hearing loss, in that they are often unable to properly hear external sounds which occur within the same range of frequencies as their "phantom sounds."  This has led to the suggestion that one cause of tinnitus might be a homeostatic response of central dorsal cochlear nucleus auditory neurons that makes them hyperactive in compensation to auditory input loss.
