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.
Tinnitus is a condition in which a clicking sound within the ear, without the existence of any external sound, causes discomfort and pain. Noise-induced hearing loss can cause tinnitus. In severe conditions, the person may find it difficult to hear, work, concentrate, or even sleep.
