The primary cause of hearing impairment can still be traced to genetics. The strange aspect of this fact is that a child may inherit deafness even when both parents suffered no hearing loss. This is due to the two types of hereditary deafness-syndromic and nonsyndromic.f deafness is due to problem in the inner ear, then it is called sensorineural hearing loss. Hearing impairment can also be classified according to when it happened. If the deafness in children happened before the development of language skills, then it is called prelingual deafness.
