Refining Measurements of Power Absorbance in Newborns: Probe Fit and Intrasubject Variability

The objectives of this work were to: (1) develop criteria to indicate whether a change in absorbance occurs in association with probe fit; (2) describe the variability in absorbance due to poor fitting; and (3) evaluate test–retest variability with probe reinsertions, excluding poor fits.

Design:

An observational cross-sectional design was used to evaluate changes in absorbance due to probe fit and probe reinsertion. Repeated measurements were recorded in 50 newborns (98 ears) who passed TEOAE screenings and were −0.11 cycles and (2) absorbance-based criterion (250 to 1000 Hz)> 0.58. Poor-fit measurements introduced statistically significant increases in absorbance up to 0.1 for 1000 to 6000 Hz, and up to 0.4 for frequencies
