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 ...

The U.S. Environmental Protection Agency has identified the level of 70 dB(A) (40% louder to twice as loud as normal conversation; typical level of TV, radio, stereo; city street noise) for 24‑hour exposure as the level necessary to protect the public from hearing loss and other disruptive effects from noise, such as sleep disturbance, stress ...
The process of language acquisition is varied among deaf children. Deaf children born to deaf parents are typically exposed to a sign language at birth and their language acquisition follows a typical developmental timeline. [1] [2] [3] However, at least 90% of deaf children are born to hearing parents who use a spoken language at home. [4]
Pendred syndrome; Other names: Goiter-deafness syndrome [1]: The normal cochlea has 2 & a half turns, but, in Pendred Syndrome, there is abnormal partitioning (the central bony core is reduced in size and complexity)and a reduced number of turns leading to a Mondini cochlea which has a basal turn and a dilated apical turn (1 & a half turns).
Children as young as 4 weeks of age can benefit from a hearing aid. These devices amplify sound, making it possible for many children to hear spoken words and develop spoken language. However, some children with severe to profound hearing loss may not be able to hear enough sound, even with a hearing aid, to make speech audible.
