Pediatric ABR Assessment With CE-Chirp Stimuli

---

1.  Chirp stimulus was first described by: Hecox and Galambos in 1974 Shore and Nuttall in 1985 Hall and Jerger in 1992 Kristensen and Elberling in 2012

2.  The spectra of the CE-Chirp is: Identical to the low frequency click spectra Identical to the mid frequency click spectra Identical to the high frequency click spectra Identical to the click spectra

3.  The four CE-Chirp octave band stimuli were designed by: Decomposing the click stimulus Decomposing the CE-Chirp stimulus Decomposing tone burst stimulus Decomposing broad band noise stimulus

4.  The CE-Chirp's advantage over a traditional click is: Longer wave V latency Shorter wave V latency Larger wave V amplitude Smaller wave V amplitude

5.  The advantage of using the CE-Chirp in newborn hearing screening is: The CE-Chirp is pleasant sounding for newborn infants The CE-Chirp can be presented at a higher stimulus level Test results are more valid Test time is shorter

6.  Cebulla and Shehata-Dieler (2012) reported the median newborn ABR hearing screening test time of: 12 minutes 2 minutes 28 seconds 2 seconds

7.  Xu and colleagues (2014) reported mean differences between VRA thresholds and ABRs thresholds to chirp stimuli in infants aged 6 to 12 months to be within: 20 dB 15 dB 10 dB 5 dB

8.  Stuart and Cobb (2014) reported ABRs to air conducted CE-Chirps at a screening level intensity in 100% of newborn infants tested with how many sweeps: 232 464 928 1856

9.  ABRs evoked by bone-conducted stimuli are indicated when: There is extra test time available ABR thresholds to air conducted stimuli are elevated ABR thresholds to air conducted stimuli are normal When the infant's parent(s)/caregiver(s) requests

10.  The relationship between air-conducted CE-Chirp Octave Band stimuli and ABR wave V latencies is best described as: Wave V latency is longer for high frequency CE-Chirp Octave Band stimuli Wave V latency is longer for mid frequency CE-Chirp Octave Band stimuli Wave V latency is longer for low frequency CE-Chirp Octave Band stimuli There is no relationship
