However, late exposure to language and delayed language acquisition can inhibit or significantly delay the cognitive development of deaf and hard of hearing children, and impact these skills. Late exposure to language can be defined as language deprivation (see Language deprivation in deaf and hard of hearing children). This experience is the ...

Early intervention, parental involvement, and other ...
Hearing protection is the use of devices designed to prevent noise-induced hearing loss (NIHL), a type of post-lingual hearing impairment. The various means used to prevent hearing loss generally focus on reducing the levels of noise to which people are exposed.
The extent to which one or other approach is beneficial depends on a range of factors, including level of hearing loss of the deaf person, age of hearing loss, parental involvement and parental language(s). Then there is a question concerning the aims of the deaf person and their community and carers.
