Objectives: To assess the sensitivity of statistical indicators used for the objective detection of speech-evoked envelope following responses (EFRs) in infants and adults.
Design: Twenty-three adults and 21 infants with normal hearing participated in this study. A modified/susa[integral]i/speech token was presented at 65 dB SPL monoaurally. Presentation level in infants was corrected using in-ear measurements. EFRs were recorded between high forehead and ipsilateral mastoid. Statistical post-processing was completed using F-test, Magnitude-Square Coherence, Rayleigh test, Rayleigh-Moore test, and Hotelling's T2 test. Logistic regression models assessed the sensitivity of each statistical indicator in both infants and adults as a function of testing duration. Results: The Rayleigh-Moore and Rayleigh tests were the most sensitive statistical indicators for speech-evoked EFR detection in infants. Comparatively, Magnitude-Square Coherence and Hotelling's T2 also provide clinical benefit for infants in all conditions after ~30 minutes of testing, whereas the F-test failed to detect responses to EFRs elicited by vowels with accuracy greater than chance. In contrast, the F-test was the most sensitive for vowel-elicited response detection for adults in short tests ( Conclusions: The choice of statistical indicator significantly impacts the sensitivity of speech-evoked EFR detection. In both groups and for all stimuli, the Rayleigh test and Rayleigh-Moore tests have high sensitivity. Differences in EFR detection are present between infants and adults regardless of statistical indicator; however, these effects are largest for low-frequency EFR stimuli and for amplitude-based statistical indicators. |
