Common Symptoms of Hearing Loss
Hearing loss is often gradual and not immediately noticed by the person affected. Sometimes friends or family will notice a person's hearing problems before the person with the hearing loss recognizes it. For instance, family members may complain that the person with hearing loss listens to the television or radio too loud and often ask them to repeat what they've just said. Or, that the person with hearing loss doesn't answer the telephone or doorbell because they didn't hear it ringing.
Although each person may experience symptoms of hearing loss differently, some of the most common symptoms may include:
