Q

Why do we need to do behavioral testing?

A

Enables parents to participate in the testing by allowing them to observe when the infant responds to sounds and when they do not
Allows for cross-check physiologic results with behavioral data by using a battery of tests to determine hearing sensitivity
Can be used to monitor performance with technology

Q

What are some things to keep in mind for testing peds?

A

Procedure selection
Influencing factors (response can be affected by development stage, condition during the test (hungry or tired), and the experience of the audiologist)
Soundfield testing (won’t provide ear specific information, but will provide information regarding whether or not hearing is sufficient to develop speech and language)
Response fatigue (tire quickly)
Importance of setup (vital to ensure assessments are reliable and precise)

Q

How is cognitive information regarding the child (to determine cognitive age) obtained?

A

Case history
Speech-language or psychoeducational evaluations
If a child has other developmental disabilities, cognitive levels will be harder to ascertain; results of specific developmental tests may be required

Q

What are some advantages of using noisemakers for hearing tests?

A

Readily available
Simple and inexpensive,
Could be used in any setting (a sound room was not required)
It was believed that infants would respond more reliably to noisemakers than to pure tone stimuli

25
What are some limitations of using noisemakers for hearing tests?
Very broad frequency responses Intensity is not easy to control
26
Can noisemakers fully assess infant hearing?
No, but it can provide some gross information about an infant’s ability to alert to sound and localize to the source
27
What are some limitations of early testing methods?
Have not proven to be sufficiently repeatable Are not good indicators of threshold; typically reveal suprathreshold level
28
What are limitations of ABR, ASSP, and DPOAEs?
They are not direct tests of hearing They may not always be able to provide a complete and accurate assessment of hearing in early infancy
29
What is the only way to collect information about an infants ability to hear and attend to auditory stimuli?
Behavioral testing
30
What does BOA measure?
An infant's awareness of sound Doesn't provide threshold information
31
Do children typically respond to sounds at threshold? (BOA)
No, they only respond to sounds that are more clearly audible (minimum response levels)
32
Does BOA have high inter- and intra-subject variability?
Yes Unable to differentiate between mild and moderate HL Dependent on state, alertness, attention, etc. Infant habituation after only a few responses
33
Should BOA results be used to determine thresholds for purposes of hearing aid fitting?
No, but they may be useful for corroboration of parent/caregiver report
34
Do infants respond at a lower threshold to speech rather than warble tones and noisemakers?
Yes They pay attention to what they want to and ignore other things
35
Is BOA known to have limited reliability?
Yes Some babies will appear to respond even though they may not have heard it Others will have heard it but do not demonstrate any observable response
36
Is cessation or initiation of sucking rate a reliable response for observing auditory behavior in infants younger than 6 months?
Yes
37
What is being observed during a sucking response?
Changes in the sucking in response to sounds Observed with bottle, nursing, pacifier (nonnutritive sucking)
38
Should the baby be hungry during the sucking response?
Yes, but not extremely Want to avoid them being mad
39
Do you need to observe the mouth of the baby up close during the sucking response?
Yes
40
41
What is an option for sucking response?
Camera with zoom in the testing room that can be controlled from the observation room
42
Is a sucking response typically present at suprathreshold?
Yes, but are frequently observed at, or close to, threshold Closer to threshold than the tests in the past
43
How fast should responses be seen?
Within 2 seconds of the sound presentation (some respond to the sound turning on and some respond to it turning off)
44
Are infants usually consistent when it comes to their pattern of response?
Yes
45
Is response time typically slightly shorter for louder stimuli?
Yes
46
How should the infant be positioned during sucking rate testing?
Infant needs to be resting in a comfortable position with full support of the head and torso and be visible to the tester Bottle or pacifier: let mother hold in arm Nursing child: let mother hold in arm
47
What is the advantage of using a car seat for sucking rate testing?
Infant will not be receiving any “signals” from the mother when he/she hears the sound
48
How many testers should there be for a sucking test?
A minimum of 2, must reach a consensus Audiologist (control room) Audiologist/audiology assistant (next to the infant) - constantly monitor the child making sure his head and torso are comfortably balanced Both need to have good visualization
49
Is consistency required for a response?
Yes, if the infant changes something else (eyes widening, moving, etc) it is not considered a response
50
What is the role of the parent during the sucking test?
Need to remain silent and not react bodily to any sound (even stiffening of the muscles especially for parents who are breastfeeding could be transmitted to the infant)– you can have the mother wear earphones Making the baby comfortable Sharing previous baby experience to sound stimulation At least one parent should be in the room: assist and understand test procedure Other parent (if present) is invited to stay in the observation room
51
Do infants only provide a limited number of responses during a session?
Yes
52
Is ear specific information always necessary for infants?
No, it may not be required for the initial visit unless a medical condition warrants ear specific info
53
If there is any evidence of hearing loss without ear specific information, what is needed?
Ear specific information Need to test under earphones
54
When should ear specific information be collected?
Same day or different day
55
What is stimuli used for frequency specific information?
Warble tones Narrow band noise
56
Can speech sounds be used to confirm warble tones/noise band threshold levels?
Yes Threshold for “ba” should be close to threshold obtained at 500 Hz Threshold for “sh” should be close to threshold obtained at 2000 Hz. Threshold for “s” should be close to threshold obtained at 3000 to 4000 Hz
57
What frequency should you begin testing at for infants?
Many normal hearing infants respond better to high-frequency stimuli, so it is reasonable to begin at a high frequency, usually 2000 Hz If SNHL is suspected, start at 500 Hz If there is a concern about ME pathology, start at 2000 Hz
58
What should you do after obtaining thresholds at 500 and 2000 Hz?
Determine the next most important piece of information For example, if thresholds at both 500 and 2000 Hz are normal, it’s more useful to test 4000 Hz than 1000 Hz. However, if hearing at 500 Hz is 30 dB HL and at 2000 Hz is 70 dB HL, testing 1000 Hz becomes crucial
59
Do you need to present the stimuli at an appropriate pace?
Yes, if it is presented too fast, the infant will ignore them
60
Should you start presenting the stimuli from silence?
Yes, sounds emerging from silence are more likely to get a response
61
Should you watch the infant closely for a response?
Yes
62
Are response patterns more apparent for loud sounds?
Yes Loud sounds help identify response types and latencies, aiding interpretation of softer sounds
63
What are other factors that influence BOA?
Spending a little time with the infant before beginning testing to ensure that they can perform the required task will increase the likelihood of obtaining reliable test results Gastrointestinal feeding tube (cannot do feeding response) Infant’s neurologic status Visually alert
64
How do you have good response reliability during BOA testing?
Predetermine what constitutes a response Stick to the chosen response (e.g., sucking) and avoid accepting other behaviors like eye widening or head turns Avoid changing response criteria during testing Ensure the response is time-locked to the stimulus presentation Responses must be repeatable Use multiple observers to increase reliability
65
What is the BOA test protocol?
Reduce thresholds in 10 dB steps and increase in 5 to 10 dB steps Take breaks as needed to calm the infant and increase usable test time If SF testing indicates hearing loss, test bone If infant is still responding, or at the next test session, test with insert earphones
66
What are some benefits of BOA?
Enables the audiologist to obtain valuable behavioral responses in infants; part of the cross-check principle Can be conducted in sound fields, with earphones or with bone oscillator, hearing aids, or cochlear implants Enables accurate fitting of technology because minimal response levels (MRLs) can be obtained
67
What are some limitations of BOA?
Requires careful observation of infant sucking by the audiologist Cannot be used with infants who do not suck (e.g., infants who use feeding tubes) Can be performed only when the infant is in a calm awake or light sleep state BOA not generally accepted in the audiology community because audiologists typically have not been trained to use a sucking response paradigm
