Write A Term Paper On Tinnitus

Tinnitus referred as ears ringing, in humans, can be caused by a variety of factors; such as high-level sound exposure, ototoxic drugs, and hearing loss. It is basically the self perception of sound in the absence of acoustic stimulation. the sound waves hit the outer ear and converge into the ear drum. The vibrations at ear drum are transferred into the inner rear through the middle ear. Once the sound waves reach inner ear, they travel through the cochlea towards the organ of corti. Further the signals on the hair cells on the organ of corti follows to the brain stem. Now, the signal travel to mesephelon and then into the auditory cortex. Tinnitus can be classified into two types: Objective and Subjective. Objective sound or somatosound is developed through an internal acoustic source activating the cochlea by air or bone conduction.
Chronic tinnitus is normally more common in men. It is figured elderly people tend to suffer from tinnitus. A study of tinnitus shows that odds of having tinnitus increases as hearing threshold levels at 4.0 KHz increase. Tinnitus can be treated through the audiological techniques or psychological or medical. Audiological techniques include, use of hearing aids, Masking, Residual inhibition, Habituation, Environmental (palliative) and Tran cranial Magnetic Stimulation. Now, medical technique include surgical excision. A benign intracranial hypertension, vascular pulsations, glomus jugular tumors, palatal myoclonus, auditory nerve transection, grid placement cortical electrical stimulation over auditory cortex, and vagus nerve stimulation paired with tones. A research study was conducted on electrically stimulating the auditory nerve by operating on
