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.
Sensorineural hearing loss occurs if the sensitive hair cells inside the cochlea are damaged, or as a result of damage to the auditory nerve (which transmits sound to the brain). In some cases, both may be damaged. Hearing loss caused by age and exposure to loud noises are both types of sensorineural hearing loss.
