Tinnitus is an annoying phenomenon, which usually occurs as a condition related to certain forms of hearing loss. Conditions frequently associated with tinnitus are: Meniere's disease, presbyacusis, otosclerosis, hyperacusis and noise damage induced forms of hearing loss.In many cases the tinnitus is a high-pitched tone.The frequency (perceived noise you experience) of the tinnitus matches the area where the hearing loss is the most profound.Simply put, the specific area where the patient hears the least sound from the outside world, is "taken over" by the noise of tinnitus. For the tinnitus sufferer, this noise is a clearly detectable sound, although objectively viewed it does not exist.
