the creation of special communication conditions in which teachers and auds help hearing impaired children acquire many of the auditory perception abilities that normally hearing children acquire naturally.
|
|
when considering auditory training for adults, two general objectives are usually relevanat

are normally learned early in life and when a hearing loss occurs in later childhood or in adulthood, some of the person's auditory skills may become impaired even though they were intact prior to the onset of the hearing loss
