Ringing in the ears, medically called Tinnitus, is a condition in which the individual hears a certain sound continuously in the ears.
The nature of this sound varies with different individuals. The sound may be whistling, buzzing or bell-like; it might be low or high; seeming to come from a far point or from inside of one's body.
Tinnitus in most cases is subjective where only the affected individual is able to hear the sounds. In some cases, the condition might also be objective wherein the doctor/examiner might be able to hear the sounds on examining.
Understanding the most common cause:
The process of sound waves travelling from the ear to the brain is facilitated by hair cells. When these hair cells are damaged, the brain does not receive signals which cause dysfunction in the activity of neurons. This dysfunctional neuron activity results in the illusion of sounds in the said individual. This illusion is referred to as Tinnitus.
Other causes that might result in Tinnitus are:
Damage around the hearing sections of the brain also might result in ringing sounds / tinnitus. Excessive noise might result into Tinnitus and if not prevented might even progress to hearing loss. There are also some drugs that may cause or worsen the condition.
