Tinnitus: A hearing disorder often triggered by exposure to noise

What is tinnitus

Tinnitus is the term for a condition which causes the sufferer to hear sounds which have no external source. Although sometimes referred to as ‘ringing in the ears’, the noises heard can be very varied, from constant buzzes and whistling to sounds like music or singing. When the noises are heard in time with the hearer’s pulse the condition is known as pulsatile tinnitus.
