Navzer Engineer at MicroTransponder, Inc. Michael Kilgard at the University of Texas at Dallas and Dr. Current treatments generally involve masking the sound or learning to ignore it. For example, when sensory cells in the inner ear are damaged from loud noise, the resulting hearing loss changes some of the signals in the brain to cause tinnitus. Something as simple as a piece of earwax blocking the ear canal can cause tinnitus, but it can also arise from a number of health conditions. While tinnitus isn't fully understood, it is known to be a sign that something is wrong in the auditory system: the ear, the auditory nerve that connects the inner ear to the brain, or the parts of the brain that process sound. Tinnitus usually comes in the form of a high-pitched tone in one or both ears, but can also sound like a clicking, roaring or whooshing sound.
The finding gives hope for a future tinnitus cure in humans.
Scientists were able to eliminate tinnitus - a persistent ringing in the ears - in rats by stimulating a nerve in the neck while playing a variety of sound tones over an extended period of time.
