Document Summary

Questions to ask parents about child: family history, do they respond to sound, are they saying 2 word utterances, tugging on the ear (history of ear infections) Gives the audiologist an idea of what to expect. Try not to read off of checklist. Pull pinna up and back to straighten canal. Used in schools or public health programs. Will adjust pure tone stimuli to 125-8000 hz. Adjust intensity by 5 db hl from 0 to 100 db hl. Deliver stimulus via headphone or bone oscillator. Graph used by audiologists to plot hearing loss. Plots intensity (db hl) as a function of frequency. Y axis = intensity in db hl. Ranges from -10 to 120 db hl. Tests the integrity of the entire peripheral system. If hearing loss is identified, we cannot localize the problem. Could be outer, middle, inner, or pathways to the brain. Or a combination of any of these.
