A common condition that results in hearing loss is chronic ear infections. Certain infections during pregnancy such as syphilis and rubella may also cause hearing loss. Hearing loss is diagnosed when hearing testing finds that a person is unable to hear 25 decibels in at least one ear. Testing for poor hearing is recommended for all newborns.
Deafness can increase until it is almost impossible to hear any sound, but it has been found that most deaf persons can hear at least one sound. If a person is totally deaf, he cannot hear a thing including his own voice. Some people are born deaf, and some lose their hearing from disease or other causes. Most hearing problems are caused by diseases that do not necessarily start in the ear but reach it from some other part of the body.
