Document Summary
Congenital vs. acquired hearing loss: pre-lingual, pre-lingual means before developed aural speech and language. If have a hearing loss may not develop these skilss normally not getting constant language stimulation or accurate feedback of his or her own speech. These types of losses have the biggest effect on social, educational, and vocational aspects: post-lingual, post-lingual means after developed language. Usually use about age 3 as a definition. Developing a significant hearing loss after this will have less catastrophic effect. Language already developed so little change in that or voice quality. Diagnosis of hearing loss: includes, interview, audiologic assessment, before we can do anything with intervention we need to accurately diagnosis and describe the hearing loss. How we proceed is going to vary greatly depending on the specifics of the type of hearing loss: case history, otoscopy, audiogram, air conduction testing, bone conduction testing. Hearing test: how do we test hearing, thresholds, speech understanding.
