[QUOTE="buckeye, post: 1328087, member: 8467"] -Everybody- will hear the TV flyback transformer type sound in a quiet enough setting. Mine has gotten louder over the years and now it takes background noise somewhere in the neighborhood of 50 decibels to cover it. Fun stuff to know: The nerves serving your inner ear are two-way. It's currently thought that hair cells and such in your cochlea work at their best when they're lightly "engaged" - sort of analogous to the way transistors are more linear father away from their on/off point. Our brain keeps a feedback loop going between itself and the sensory cells, thereby maximizing sensitivity. Supposedly, one cause of tinnitus is the brain trying too hard to engage damaged sensory cells. It'll 'turn up the volume' saying, "Where are you?" to the damaged cells until we actually perceive a sound. Since hearing loss tends to affect high frequency first, that's what we hear in tinnitus most often. Surgically induced deafness (cutting auditory nerves) does -not- always cure tinnitus. What I've read suggests that it almost never does, in fact. The sound often lingers, similar to the "phantom limb" deal. There's a little bitty muscle connected to the back of your eardrum, the tensor tympani. It keeps the eardrum under tension and increases that tension in the presence of sustained noise, making our ears "numb" after ... well, shooting for a while, for example. It also tightens in response to a puff of wind on the eyeball, a curious vestigal reflex... If this muscle goes into spasm (like my left one does pretty much every night), you can hear the eardrum rattling back and forth. Sufficient exposure to loud noise (85dB and up these days) temporarily (permanently, given repeated exposure) increases tinnitus and alters your threshold shift (the quietest sound you can hear at a given frequency). My threshold shift has moved enough that what used to be nearly inaudible tinnitus is now exposed, at least that's how it appears subjectively. There's no cure, although "Tinnitus Retraining Therapy" can help a person deal with insufferable tinnitus. It's all about learning to embrace it, basically, just as a previous poster said. The mind is a wonderfully plastic thing, and you can rewire your mind to a certain degree just by force of will. The goal is to remove the powerfully negative associations with tinnitus and accept it as a neutral part of life.
