- Abstract
The aim of this study was to investigate the test-retest reliability of acoustic reflex (AR) test measured from a group of 6-week-old infants who passed a transient evoked otoacoustic emission test and an automated auditory brainstem response screening test. Ipsilateral acoustic reflex thresholds for a 2 kHz pure tone and broadband noise were recorded from 70 infants using a Madsen Otoflex Diagnostic Immittance meter with a probe tone of 1000 Hz. The mean AR thresholds obtained in the first test were 67.3 and 80.9 dB HL for the broadband noise and 2 kHz tone, respectively. The results for the retest condition did not differ significantly from those of the first test. The AR test also showed high test–retest reliability as demonstrated by intra-correlation coefficients across the test–retest conditions of 0.783 and 0.780 for the broadband noise and 2 kHz pure tone stimuli, respectively. Findings from this study suggest that the AR test could be used to establish reliable AR thresholds in 6-week-old infants.
