Tinnitus affects about 10% to 15% of the population. It is often described as a ringing, buzzing or pulsating sound in the ear, but is defined as a phantom auditory sound. About 5% of the population reports severely intrusive tinnitus affecting day-to-day activities. Many people who suffer from tinnitus also experience tiredness, irritability, poor concentration, anxiety and depression that can be severe. Wax buildup, eardrum perforation, ear infection, and noise exposure have been associated with the onset of tinnitus. Specialized tinnitus testing and therapy are now available and have high success rates for relief.
