Why do BOA:
-Only ___ testing truly tests hearing, since it measures the response of the entire ___ ___ from the outer ear through the cerebral cortex
-Behavioral tests measure what an infants actually ___, so they are measures of ___ hearing abilities |

-By 6 months of age, hearing sensitivity in the ___ frequencies improves but thresholds at ___ Hz remain elevated |

Maximizing Observation of the Sucking Response:
-Sucking can be observed with a ___ or a ___
-Family should be instructed to bring the infant ___ so that
he will be ready to suck
-The infant should be ___ and do what is in their typical ___ (bottle, breast, etc.)
-Mother needs to be comfortable with ____ nursing
-Best way to observe is to see the infant’s ___ close up,
however having your face in the infant’s face may be ___ |

Term
| Responses should fall within a reasonable ___ to the stimuli |
|

Term
Positioning the Infant:
-Resting in a comfortable position with full support of the ___
and ___ and must be visible to testers
-Can be in ___ ___ or an infant ___
-___ movements from the mother can be transmitted to the infant, therefore changes in sucking can occur but not be related to stimuli
-Sometimes helpful to have the mother wear ___ to
prevent her from hearing and being influenced by the sound |

Soundfield v. Earphone testing:
-Infants will provide limited information before they ___ or ___ to the task
-The goal of the initial evaluation is to determine if the infant
has sufficient hearing to...
-Should the initial visit evaluation indicate that hearing is
normal in at least one ear utilizing soundfield it may not...
-However, if initial testing indicates hearing is not within normal limits , then.... |
|
Definition
| fatigue; habituate; develop speech and language; be necessary to analyze each ear separately at that visit; ear specific information is critical so that management can proceed |
|
|
Term
| What kind of stimuli do you use with infants? |
|
Definition
| warble tones/narrow band noise. Narrow band noise is typically easier for an infant to respond to |
|
|
Term
Speech awareness thresholds to low (ba), mid (sh) and high (s)
frequency speech stimuli can be used to confirm ___ tone/nbn thresholds |
|
Definition
|
|
Term
-Normal hearing infants typically respond better to ___ frequency stimuli, so reasonable to begin at ___ Hz
-If concerns about middle ear pathology could have ___ frequency hearing loss
-However, is SNHL is suspected may want to start at ___ Hz, since may have better ___ frequency thresholds |

Term
| What are some limitations of BOA? |
|
Definition
-it may not yield threshold information
-possible tester bias, was response present/absent?
-Responses habituate quickly
-There are a wide variety of responses that can be observed-what do you consider a response? |
