Problems with the auditory system, such as hearing loss or minor blockages, can cause ringing in the ears, states WebMD. This ringing, clicking or roaring sound can also be a warning sign of a more serious disease, such as anemia or Ménière's disease.
Ringing in the ears, known as tinnitus, is a symptom of auditory problems that tends to be more prevalent in people older than 40, says the U.S. Department of Health and Human Services. While most often referred to as a ringing, it sometimes arises as a roaring or clicking sound.
Often it is the result of either hearing loss associated with age or of other problems within the auditory system; however, it can indicate more serious health problems, such as brain tumors and thyroid abnormalities, notes the National Institute on Deafness and Other Communication Disorders. For some it’s merely an annoyance, while others suffer from a constant ringing in the ears that causes loss of sleep and other health problems. If the symptoms persist for three months or more, it is recommended to consult a doctor, states WebMD.
