Tinnitus
Tinnitus refers to the perception of a sound in the ears in the absence of any identified external auditory stimulus and sound waves to produce the normal physiological mechanical and vibratory signals associated with hearing.
The perception of sound during tinnitus can be described as a constant or intermittent buzzing, ringing or humming sound or a pulsatile whooshing sound that can occur in one or both ears. Loud noise, poor blood circulation, food sensitivities and stimulants like caffeine and nicotine can all make it worse.
