Westerling Early Hearing Detection and Intervention CDC’s 2005 Science Ambassador Program Modeling OAE Screening: Modeling OAE Screening Early hearing detection and intervention (EHDI) programs Building our model Modeling Hearing ear Deaf ear - blocked canal Deaf ear - cochlear hair cell defect Reviewing the activity Why are EHDI programs so important? : Why are EHDI programs so important? It is important to identify children with hearing loss as early as possible so that intervention can begin. Intervention is important for speech, language, cognitive, and psychosocial abilities. What are the EHDI program’s goals?: What are the EHDI program’s goals? The 1-3-6 plan: Initial hearing screening before 1 month Follow-up hearing tests and diagnosis before 3 months Intervention (hearing, language, family support) before 6 months Methods for infant hearing screening: Methods for infant hearing screening Otoacoustic emissions (OAE) Automated auditory brainstem response (AABR) Slide6: The OAE test Infants can be tested using otoacoustic emission screening (OAE). OAE detects the tiny sounds made by the haircells in the cochlea. OAE is fast and not invasive. OAE is a first step to determine infant hearing status. Slide7: OAE Modeling Activity Water bottle Marble Rubber band Piece of paper Scissors Materials you will need:Slide8: OAE Modeling Activity Water bottle represents the ear canal. Marble represents sound wave. Rubber band represents cochlear hair cells. Piece of paper represents ear canal blockage. Model parts are analogiesSlide9: OAE Modeling Activity Remove lid and turn bottle upside down. Cut bottom off of bottle. Stretch rubber band vertically over top and bottom of bottle Preparing your ear modelSlide10: OAE Modeling Activity Drop marble into bottle. What do you observe? How is this similar to OAE? Modeling the hearing ear Slide11: OAE Modeling Activity Stuff a piece of crumpled paper into your model ear. Drop marble into the bottle. What do you observe? Modeling the obstructed ear Slide12: OAE Modeling Activity Remove rubber band from model. Drop marble into model ear. What do you observe? Modeling an ear without cochlear hair cellsSlide13: OAE screening detects the tiny sounds made by the cochlear hair cells in the inner ear. Blockages or other problems in the outer and middle ear may prevent the hair cells from functioning, producing no echo. OAE Modeling Activity: Putting it all togetherOAE Modeling Activity: Putting it all together: Absence or problems with the hair cells can also be noted in the OAE test due to the lack of echo. Nerve impulses to the brain and brain interpretation of those impulses are not tested by OAE screening. OAE Modeling Activity: Putting it all togetherSlide15: EHDI for more information: www.cdc.gov/ncbddd/ehdi Slide16: OAE Modeling Activity: When can a person have their hearing tested? Why is it important to know an infant’s hearing status? How can hearing be preserved? How does a cochlear implant work? Optional Questions for further study You do not have the permission to view this presentation. In order to view it, please contact the author of the presentation.
