Language deprivation in deaf and hard-of-hearing children is a delay in language development that occurs when sufficient exposure to language, spoken or signed, is not provided in the first few years of a deaf or hard of hearing child's life, often called the critical or sensitive period. Early intervention, parental involvement, and other ...
Prelingual hearing loss can be considered congenital, present at birth, or acquired, occurring after birth before the age of one. Congenital hearing loss can be a result of maternal factors (rubella, cytomegalovirus, or herpes simplex virus, syphilis, diabetes), infections, toxicity (pharmaceutical drugs, alcohol, other drugs), asphyxia, trauma, low birth weight, prematurity, jaundice, and ...
Hearing loss is a partial or total inability to hear. [5] Hearing loss may be present at birth or acquired at any time afterwards. [6] [7] Hearing loss may occur in one or both ears. [2] In children, hearing problems can affect the ability to acquire spoken language, and in adults it can create difficulties with social interaction and at work. [8]
Language exposure for children is the act of making language readily available and accessible during the critical period for language acquisition.Deaf and hard of hearing children, when compared to their hearing peers, tend to face barriers to accessing language when it comes to ensuring that they will receive accessible language during their formative years.

Hearing loss that results from changes in the middle ear is called conductive hearing loss. The middle ear contains three tiny bones that help transfer sound from the eardrum to the inner ear. Some forms of nonsyndromic deafness involve changes in both the inner ear and the middle ear; this combination is called mixed hearing loss.
Children with recurrent episodes of acute otitis media and those with otitis media with effusion or chronic suppurative otitis media have higher risks of developing conductive and sensorineural hearing loss. Globally approximately 141 million people have mild hearing loss due to otitis media (2.1% of the population). [74]
The probability is higher if both parents have the dominant gene (and typically both have hearing loss) or if both grandparents on one side of the family have hearing loss due to genetic causes. Because at least one parent usually has a hearing loss, there is prior expectation that the child may suffer from hearing loss.
