Efficient Detection of Cortical Auditory Evoked Potentials in Adults Using Bootstrapped Methods
Conclusion:
When subjects’ CAEP morphology is approximately known before the test, then the DTW algorithm provides a highly sensitive method for CAEP detection. (Source: Ear and Hearing)

Improved Sensitivity of Digits-in-Noise Test to High-Frequency Hearing Loss
Conclusions:
Of the filters used, DIN sensitivity to higher frequency hearing loss was greatest using the 4-kHz low-pass filter. These results suggest that low-pass filtered noise may be usefully substituted for broadband noise to improve earlier detection of HFHL using DIN. (Source: Ear and Hearing)

Investigation of an Outcomes-Driven, Computer-Assisted Approach to CI Fitting in Newly Implanted Patients
Objective:
To evaluate the efficacy of outcomes received by newly implanted cochlear implant recipients when an outcomes-driven, computer-assisted approach to cochlear implantation fitting was used. This approach, referred to as “Fitting to Outcome eXpert,” or FOX, was developed by Otoconsult in Antwerp, Belgium.
Design:
Thirty-one newly implanted subjects participated in a nonrandomized, single-subject, repeated measures design that involved a within-subject comparison of preoperative and postoperative speech recognition scores. Sound processors for all subjects were programmed using the FOX software that u...

Effects of Otosclerosis on Middle Ear Function Assessed With Wideband Absorbance and Absorbed Power
Conclusions:
Consistent with previous studies, wideband absorbance showed better sensitivity for detecting the effects of otosclerosis on middle ear function than static acoustic admittance at 226 Hz. This study showed that wideband absorbed power is similarly sensitive and may perform even better in some instances than absorbance at classifying ears as having otosclerosis. The use of a group that was age- and sex-matched to the Oto group generally resulted in greater differences between groups in the high frequencies for absorbed power, suggesting that age-related norms in adults may be useful for the wideband clinica...

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 introd...
