The two most common hearing conditions associated with aging are presbycusis (prez-bee-QUE-sis) and tinnitus (ti-NYE-tis). Presbycusis causes you to have problems hearing high-frequency sounds such as speech, while tinnitis causes a ringing, buzzing, or hissing in your ear that may sound like running water or the inside of a seashell. If family members are constantly asking you to lower the volume on the television or you're having trouble hearing what others are saying, it's probably a good idea to make an appointment with your family doctor. In some cases, the diagnosis and treatment can take place in the office. In others, you may be referred to a specialist called an otolaryngologist (aut-oh-lar-inj-AWL-o-jist)to diagnose conditions associated with the ear, nose, and throat. This doctor will consider your medical history, conduct a thorough exam, and recommend additional tests if needed. For example, you may be refereed to an audiologist (aw-dee-AWL-o-jist) who will administer a series of tests to check your ability to hear sounds at different volumes and pitches. Then, depending on the type and severity of your condition, the audiologist will probably recommend a hearing aid suited for your particular needs. For more information about diagnosing hearing problems, contact your doctor.
